jQuery val()contains()
问题描述：
我想知道textarea值是否包含某个单词.这对我不起作用.
I want to know if the textarea value contains a certain word. This is not working for me.

if($(value).contains('iframe')){...
答
尝试使用javascript
Try javascript
if (value.indexOf('iframe') >= 0) {
JQuery 包含用于DOM元素，而不是字符串.
JQuery contains is for DOM elements, not strings.
