jQuery：用字符串搜索文本

Question

我试试这个：

form['comment'] = '<blockquote>test</blockquote><a href="#">test</a> <Your reply here>';

if($(form['comment']).search('<Your reply here>'))
    alert(1)
else
    alert(0)

但是有这个错误：

  

TypeError：$（form.comment）.search不是函数

我解决了这个问题：

if(form['comment'].value.search('<Вашият отговор тук>') != -1)
    alert(1)
else
    alert(0)

Answer 1

你想要的是$(form['comment']).text().search()

所以：

form = [];
form['comment'] = '<blockquote>test</blockquote><a href="#">test</a> <Your reply here>';

if(form['comment'].search('<Your reply here>') != -1)
    alert(1)
else
    alert(0)​

Here's a working example

Answer 2

要找出匹配字符串的其他内容，您不需要jQuery！。

var comment = "<blockquote>test</blockquote><a href="#">test</a> <Your reply here>",
    search = "<Your reply here>";


comment.indexOf( search ) != -1;  //  indexOf returns -1 when search does not match
/<Your reply here>/.test( comment ); // returns true when search is in comment.
