Jquery不会从jquery生成的控件触发 [英] Jquery is not firing from controls generated from jquery

问题描述

我有一个jQuery函数，可以在点击一些添加按钮时生成输入文本。

生成的代码如下：



< input type =textid =txtNumname =some model bindingclass =FireEvent/>





有一个jquery函数：

$（。FireEvent）。更改（

alert（called）;

）;



所有这些代码都在.Ready（）函数仍然在文本更改时此事件未被触发。



i还试过$（。FireEvent）。bind（input，function（）{}）;这也是行不通的。



但是如果我尝试从我视图中的控件中触发此事件，那么它的工作非常完美。

ie

@ Html.TextBox（name，，new {@class =FireEvent，@ id =someId}）;

或

< input type =textid =someIdname =some bindingclass =FireEvent/>

解决方案

（。FireEvent）。更改（

alert（called）;

）;

i也试过

（ FireEvent。 ）结合（ 输入，函数（）{}）。这也是行不通的。

@ Html.TextBox（name，，new {@class =FireEvent，@ id =someId}）;

在创建事件时将事件附加到新元素，或使用将事件绑定到选择器的on方法



http://api.jquery.com/on/ [ ^ ]



on适用于首次运行代码后创建的元素，但请注意它有性能损失。

I have a jQuery function that generates input text on click of some add button.
generated code looks like:

<input type="text" id="txtNum" name="some model binding" class="FireEvent" />


there is a jquery function:
$(".FireEvent").change(
alert("called");
);

all this code is in .Ready() function still on text change this event is not triggered.

i have also tried $(".FireEvent").bind("input",function(){}); this is also not working.

However if i try to fire this event from controls that are in my view it works perfect.
i.e.
@Html.TextBox("name", "", new { @class = "FireEvent", @id = "someId" });
Or
<input type="text" id="someId" name="some binding" class="FireEvent" />

解决方案

(".FireEvent").change(
alert("called");
);

all this code is in .Ready() function still on text change this event is not triggered.

(".FireEvent").bind("input",function(){}); this is also not working.

Either attach your events to the new elements when you create them, or use the "on" method of binding an event to a selector

http://api.jquery.com/on/[^]

"on" works for elements created after the code is first run, but note it has a performance penalty.
