how to use EJS

Hello,
I am new, I do not understand why this code does not work.

My html :
<html>
 <head>
  <script type="text/javascript" src="ejs_production.js"></script>
 </head>
 <body>  
  <script type="text/javascript">
   var data =  {supplies : ['mop', 'broom', 'duster']};
   var result = new EJS({url: 'templates/cleaning.ejs'}).render(data);
   document.getElementById('supply_list').innerHTML = result
  </script>
 </body>
</html>

My template :
<!--template/cleaning.ejs-->
<h1>Supplies</h1>
<ul>
<% for(var i = 0; i<supplies.length; i++) {%>
   <li><%= supplies[i] %></li>
<% } %>
</ul>

Help me, thank you

EJS transforms primitive values into objects

render : function(object, extra_helpers){
        object = object || {}
        this._extra_helpers = extra_helpers;
        var v = new EJS.Helpers(object, extra_helpers || {});
        return this.template.process.call(object, object,v);
    },

this should be:
render : function(object, extra_helpers){
        object = typeof object == "undefined" ? {} : object;
        this._extra_helpers = extra_helpers;
        var v = new EJS.Helpers(object, extra_helpers || {});
        return this.template.process.call(object, object,v);
    },

otherwise if object is 0 it will make a {} out of it

Link is removed from inside to outside of the span when template renders

To reproduce the problem use the code above:
            <a href="javascript:;" class="full">

                <span class="lead"></span>
                <span class="pin">

                    <span class="item_name">title</span>

                    <span class="item_sup_info">  0 miles away<br />Call: <a href="tel:323213313">323213313</a></span>

                </span>
                        </a>

When the template renders i get the following:
                        <a href="javascript:;" class="full">
                <span class="lead"></span>
                <span class="pin">
                    <span class="item_name">La Belle Auberge</span>
                    <span class="item_address">54 r Cambronne 75015 Paris</span>
                    <span class="item_sup_info">  0 miles away<br>Call: </span></span></a>
                        <a href="tel:323213313">323213313</a>

EJSView.prototype.partial

Hi, 

Do you have an idea why the partial method was removed in the last version of 
ejs.

Thanks in advance.

EJS.update from json url

EJS.update throws javascript error: 'expected ;' in case you pass json url as 
second parameter to update function. It should enclose json string into 
parentheses to work properly(at least in IE9). The fix is to replace line 112 
with var object = eval( '('+request.responseText+')' );

String.prototype monkeypatching

rsplit and chop are unnecessary additions to String.prototype, considering
they are only used a combined 3 times, and only within the library. Locally
scoped functions would suffice and would avoid modifications to the global
namespace (important when writing library code.) It seems these additions
are an artifact of the Ruby port, but are unnecessary and potentially
harmful here.

Patch is attached.

Uncaught TypeError: Cannot read property '0' of undefined

In the template I use external variables. For this particular error, I use 
"swk_menu":

var swk_menu = [{"section_link":["Support 
Technique","module","function"],"links":[["name","module","function"],["name","m
odule","function"]]},{"logo_url":"img\/error_FileNotFound.png","logo_name":"test
","logo_module":"","links":[["name","module","function"],["name","module","funct
ion"]]}];

template:
<!-- Build menus -->
<% 
for(m in swk_menu) { 
    var menu = swk_menu[m];
    %>
    <div class="swk_menu">
        <div class="swk_menu_logo">
            <span class="swk_menu_link" onclick="swk.openTab();"><%= menu.section_link[0] %></span><br />
        </div>
        <%
        for(sm in menu.links) {
            var submenu = menu.links[sm];
            %>
            <span class="swk_menu_link" onclick="swk.openTab('<%= submenu[1] %>', '<%= submenu[2] %>');"><%= submenu[0] %></span><br />

"menu.section_link[0]" trigger the error. but in the same template I can alert 
it just fine. The same kind of code works well in the "submenu" area.

I don't get it...

Render pre-compiled ejs

Hi,

Grunt.js has a plugin that pre-compiles EJS, but I can't figure out how to 
render it. Any ideas?

How do you include a static html page in an ejs template?

What steps will reproduce the problem?
1. I have got an ejs template that is displayed via an express powered app.
2. There is an angular template that is duplicated across several ejs templates
3. How can I include this static template in ejs templates so I avoid 
duplication?

Can no longer have a helper that begins with "include"

In EJS 0.6.1, I had two view helpers, include_css and include_js. However, upon 
upgrading to 0.8.2, these names caused errors. It seems as if having a view 
helper that begins with the string "include" immediately triggers partial logic?

Ternary operator with undefined variables

<%= message ? message : 'No message' %>

When the variable message === undefined, the compiler throws an exception, even 
though a regular IF statement should just evaluate the expression to FALSE.

By the way, this executes correctly:

<%= typeof message != 'undefined' ? message : 'No message' %>


I am using the ejs_1.0_developer release (downloaded two days ago) as a Node.js 
module. [Cygwin environment running on Windows 7]

EJS introduces global variables

What steps will reproduce the problem?
1) Use EJS.render inside of a QUnit unit test.
2) Load up the unit tests in a browser.
3) Select "noglobals"
4) Rerun unit tests - watch the test turn red because of "scanline, regex, line"

What is the expected output? What do you see instead?
Expected output - no failing tests with "noglobals" checked
Seeing - failing tests due to introduced global variables with "noglobals" 
checked

What version of the product are you using? On what operating system?
EJS 1.0 on OSX.


See attached unit test.  A fix is contained in file under 
qunit_errors/ejs_fixed.js

<h1>,<h2>,<h3> in templates cause "unspecified" error in i.e. 7.

What steps will reproduce the problem?
1. Create an ejs template that uses the [%%] style tags
2. add an <h3> (or any heading tag 1-5) to the template
3. render template

What is the expected output? What do you see instead?
internet explorer gives "unspecified error".  FF/chrome/safari all fine.

What version of the product are you using? On what operating system?
1.0 on PC/internet explorer, and Mac safari/ff/chrome

I have verified, definitively that explorer can't render ejs templates that
include heading tags with numbers in them (i.e. h1, h2, etc.)  working
around by using custom p tags.

Escaping HTML

Is it possible to escape/sanitize code, similar to Rails? Example:

<%=h(data) %>,
or
<%=sanitize(data) %>
or probably just a double percentage?
<%%= data %>

I feel this is pretty important feature to have.

Error compiling with Closure Compiler

When compiling ejs.js with Closure Compiler 
(https://code.google.com/p/closure-compiler/), I get the following error:

ERROR - The use of scope variable e is not allowed within a catch block with a 
catch exception of the same name.
                    var e = new Error();

This is triggered by ejs.js:365, near the end of the EJS.Compiler.prototype 
definition. The fix is pretty easy: just name the inner declaration of 'e' 
something else.

We're using EJS as part of much larger JS app, and would rather compile it 
together with our other files, rather than use the pre-compiled version. In 
addition, we don't use the view helpers, so this helps cuts down on file size.

.update function with only element as function parameter fails

What steps will reproduce the problem?
1. Use .update function with only one parameter (the element where the template 
is shown). If you add a second parameter Hello World appears although the 
second parameter is useless.


What is the expected output? What do you see instead?
Hello World is the expected output. Instead i see nothing.

3. the un-parsed source of #identification is inserted into #something

the actual parsed template

What version of the product are you using? On what operating system?
latest svn trunk

Please provide any additional information below.
change line 57 of ejs.js on trunk to this:

        this.type = options.type || '['


from this:

        this.type = '['

I use this so i can do 

<script type="template/ejs">
</script>

so i don't have to escape anything in my templates.  better than a pre or area 
tag

:-)

Error using img_tag in IE

My code looks like this

    <% if(action_type == "registration") { %>
        <%= img_tag("/images/actions/news_feed/welcome.png", "welcome", {class : "icon"} %>
    <% } %>

This is giving me an unexpected identifier error in IE 7 and 8. If I remove the 
img_tag and replace it 
with a html include it works correctly.

    <% if(action_type == "registration") { %>
        <img src="/images/actions/news_feed/welcome.png" alt="welcome" class="icon"/>

Please make the EJS construtor accept element's of type "script"

It would be really nice if the constructor could not only check for "value" or 
"innerHTML" but also "text" to get the value form <script>-elements.
Then it would be possible to embed ejs script on a page without "abusing" the 
usage of textarea just to be able to type '< characters. I.e. it would be 
possible to do:
<script type="text/ejs">
<li>
    <a href='supplies/<%= supplies[i] %>'>
        <%= supplies[i] %>
    </a>
</li>
</script>

I have tested this approach on pretty much all browsers and it works like a 
charm, other libraries use it as well, such as dojo for their templating.

Will EJS work alongside ASP.NET?

What steps will reproduce the problem?
1. Load Visual Studio 2010
2. Create new website solution
3. Try using EJS

What is the expected output? What do you see instead?

Expect to see page validated correctly and ready to build. Instead we would 
supposedly see many errors saying the back-end code is not valid or recognised.

What version of the product are you using? On what operating system?

Any version of EJS that uses <% %> as it's tag markers. Any operating system.

Please provide any additional information below.

Was this discussed before using an already atandard tag marker? Are there any 
plans to make this framework work alongside ASP.NET? What were the developers 
thinking when they came up withtheir <% %> tag markers?

Javascript error in IE8

I try to display a list of elements (users in this case). Il works perfectly in 
Firefox and Chrome, but I have an error in IE (the list doesn't appears).

Error given by IE : 
----------------------------------
Message : '(' expected
Line : 357
Character : 3
Code : 0
URI : http://localhost/.../ejs.js
----------------------------------

Here is my code... in the js file :

render("list.html", {users: users});

And then, in HTML page :

<% for each(user in users) { %>
    <tr id="user-<%= user.id %>">
        <td><%= user.name %></td>
        <td><%= user.login %></td>
        <td><%= user.password %></td>
        <td><a href="#/user/<%= user.id %>">View details</a></td>
    </tr>
<% } %>


Line 357 in EJS 1.0 corresponds to :
try{
    eval(to_be_evaled);
}catch(e){

Do you have any idea of what could cause this? Does it result from my code or 
from EJS ?

Thank you in advance for your reply (and sorry for my broken English !).
