使用jQuery附加和调用动态javascript函数 [英] Append and call dynamic javascript function with jQuery

问题描述

您可以创建动态javascript函数并立即调用它吗?

Can you create a dynamic javascript function and immediately call it?

我已经发现您不能使用append中的回调.

I already found that you can't use the callback from append.

建议的无效代码:

<script type="text/javascript">
var count=1;
$(document).ready(function(){
    $(".main").append('
       <script type="text/javascript">function init'+count+'(){alert("'+count+'");}<'+'/script>
    ');
    window['init'+count]();
});
</script>
<div class="main"></div>

将其缩小到同步问题.在附录和窗口之间放置alert("")使其可以工作，但这并不是真正有用的解决方法，因为当我将此代码放入循环中时，计数可能会增加到100. 猜猜我必须继续寻找.

Narrowed it down to a synchronization problem. Placing alert("") between append and window makes it work, but that is not really a useful fix because the count might go up to a 100 when I place this code in a loop. Guess I'll have to keep looking.

推荐答案

这应该可以，但是您的引用不正确. append("和")中不应有任何未转义的双引号.试试:

That should work, but you aren't quoting correctly. There shouldn't be any unescaped double quotes within append(" and "). Try:

$(".main").append("
       <script type=\"text/javascript\">function init'+count+'(){alert(\"'+count+'\");}<'+'/script>"
    );
