javascript - jQuery hasClass doesn't work for me? -


In the following code, hcl does not work and the result is false. Why do I, in the warning?

Online demo:

HTML: 

  & lt; Span & gt; & Lt; Div class = "add" & gt; & Lt; / Div & gt; & Lt; / Span & gt;

JS: 

  Warning ($ ('span'). Hcl ('add'));

I think there may be misunderstanding what you can do. It checks whether one of these elements has been entrusted to one. From:

Determine whether any of the matched elements is assigned to a given class.

If you want to see that element / Em> use an element with that class:

The set of matching elements Reduce those people who have ancestry that match the selector or DOM element.

is alert ($ ('span'). ('Add'). Length> 0);

I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
