对OC返回的NSString/NSArray/NSDictionary调用toJS()
方法会得到JS里对应的类型:
var num = self.dataSource()[indexPath.row].sringValue();.toJS();
cell.textLabel().setText(num +"js");
详见wiki https://github.com/bang590/JSPatch/wiki/Base-usage
from jspatch.
NSNumber回传到JS中是JS里的Number类型,转成字符串可以用JS中的toString()方法。
from jspatch.
var num = self.dataSource().objectAtIndex(indexPath.row())
cell.textLabel().setText(num + "js")
from jspatch.
@albert438 没注意到它这里原来是number,其实不用toString()
也能得出结果:1+"JS"=="1JS"
from jspatch.
@bang590 👍 已改正。
他这里报错的原因是在这里,self.dataSource()[indexPath.row],self.dataSource()返回的是一个NSMutableArray对象,所以在JS中不能用中括号。楼主要用中括号的话要转成JS对象:
var jsArray = self.dataSource().toJS()
cell.textLabel().setText(jsArray[indexPath.row()] + "JS")
from jspatch.
确实是中括号的问题 ,使用中括号后,取出来的值为 undefined。虽不报错,但是拿不到正确类型。js 语法与 OC 混用了。问题已经解决一下两种都可以:
var jsArray = self.dataSource().toJS()
cell.textLabel().setText(jsArray[indexPath.row()] + "JS")
var num = self.dataSource().objectAtIndex(indexPath.row())
cell.textLabel().setText(num + "js")
from jspatch.
