more clear error message for requirejs not defined exception

need clear error message for wrong transform object declaration

Currently, if the declared transform object is with wrong property name(_get_value and _set_value), there is nothing to warn developer to notice that.

make Aj can be load by require

Now Aj use require to organize its own modules, but Aj does not follow the AMD to
exports itself.

We need to ask Aj to be requirejs loadable.

arrayassistant.getItem always return the last item of array

getItem should return the current bound item of array but it now always returns the last item of array.

_transform does not work with faked field "_index"

_transform is implemented as a part of value monitor but _index was treated as a special field out of monitoring, which causes the _transform mechanism is not applied to _index.

请问有中文使用文档吗？

more clear error message when binding on undefined variable

The current error message is difficult to understand what is wrong for developers.

convenience of attribute operatable selector should support more operator

at least, for the following two operation, we need support "not" operation:

css class on/off: [class:current?]
property assign: [checked?]

possible solution is as following:

[class:current?!]
[checked?!]

dummy placeholder for array binding confuses order related pseudo css selectors

The framework insert a hidden tag to the original place of binding target as a place holder, which tag is as the same name of the original tag, which cause some pseudo selectors failed, such as :first-child, :last-child, :n-th

watch on array does not work correctly

If we watch to a existing array and then add items to the existing array, the watch function will not work correctly:

  Aj.init(function ($scope) {

    $scope.data = {
      list: []
    };

    $scope.snippet("ul").bind($scope.data, {
      list:{
        _duplicator: "li",
        _item: {
          "nnn": {
            _selector: ".x-watch",
            _watch: {
              _fields: ["name"],
              _cal: function(v){
                console.log("cal", v);
                return v+"-watched";
              }
            },
            _render: function(target, nv, ov, ctx){
              console.log("args", arguments);
              console.log("idx:", ctx.getArrayAssistant().getIndex());
              target.text(nv);
            }
          }
        }
      }
    });

    $scope.data.list.push({
      name: "name-" + i
    });
}

Workaround is to reassign a new array reference to replace the existing array:

    $scope.data.list = Aj.util.clone($scope.data.list);
    $scope.data.list.push({
      name: "name-" + i
    });

binding option data with customized _value/_text function cause exception

At form-option.js,

var retrieveTargetPropMetaRoot=function(meta){
  var checkKeys = Object.keys(meta);
  if (checkKeys.length == 0) {
    return meta;
  }else if(checkKeys.length == 1){
    if(checkKeys[0] === "_duplicator"){
      return meta;
    }else if(checkKeys[0] === "_item"){
      return meta;
    }else{
      return retrieveTargetPropMetaRoot(meta[checkKeys[0]]);
    }
  }else if(checkKeys.length == 2){
    if(checkKeys.indexOf("_duplicator") && checkKeys.indexOf("_item")){
      return meta;
    }else{
      throwMalformedOptionMeta(meta);
    }
  }else{
    throwMalformedOptionMeta(meta);
  }
}

The following if statement is always false since the indexOf will return 0 for any of them.

    if(checkKeys.indexOf("_duplicator") && checkKeys.indexOf("_item")){

we need fix the judgment as ">= 0"

watch _render does not work for asSingleCheck bound field

If we watch a field which is bound as asSingleCheck, the _render of watch field does not work:

    $scope.snippet("body").bind($scope.data, {
      tdata: [
        Aj.form().asSingleCheck(),
        //"#tdataprev"
      ],
      "@tdata":{
        _selector: "#tdatawatch",
        _watch:{
          _fields: ["tdata"],
        },
        _render: function(target, value){
          target.text(value + ":www");
        }
      }
    });

ArrayAssistant should have setItem method

currently we can retrieve the current item by getItem, but there is no way to replace current item.
