Jquery/javascript, filtering html object from ajax response
提问by rjm
I have this piece of html:
我有这段 html:
<div id="1">
<div class="text">
Text for div 2
</div>
<img src="images/image1.jpg"></img>
</div>
<div id="2">
<div class="text">
Text in div 2
</div>
<img src="images/image2.jpg"></img>
</div>
Which I grab with a simple .ajax-call
我用一个简单的 .ajax 调用抓住了它
var html = $.ajax({
url: "htmlsnippet.html",
cache: false,
async: false,
dataType: "html"
}).responseText;
If I filter it with:
如果我过滤它:
var htmlFiltered = $(html).filter("#1");
it works just fine, I get the whole div with id="1",
but if I use:
它工作得很好,我得到了 id="1" 的整个 div,
但如果我使用:
var htmlFiltered = $(html).filter("#1 .text");
the htmlFiltered variable is an empty object. I can't figure out what I'm doing wrong.
htmlFiltered 变量是一个空对象。我无法弄清楚我做错了什么。

You should store it this way:
你应该这样存储:
$.ajax({
url: "htmlsnippet.html",
cache: false,
async: false,
dataType: "html",
success: function(data){
html = data;
}
}
EDIT: Your way of obtaining html works, but it's not recommended.
You can't grab your last element because you're using filter
instead of find
, so you should have:
编辑:您获取 html 的方式有效,但不建议这样做。
您无法获取最后一个元素,因为您使用的是filter
而不是find
,因此您应该:
var htmlFiltered = $(html).find("#1 .text");
instead of
代替
var htmlFiltered = $(html).filter("#1 .text");
Also W3C recommends not to have numeric IDs.
W3C 还建议不要使用数字 ID。
EDIT 2: This should work:
编辑 2:这应该有效:
var htmlFiltered = $(html).filter("#1").find(".text");
Hope this helps. Cheers
希望这可以帮助。干杯

If you don't need any special functionality given by the full $.ajax
method, you should give $.load()
a try:
如果您不需要完整$.ajax
方法提供的任何特殊功能,您应该$.load()
尝试一下:
The .load() method, unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.
.load() 方法与 $.get() 不同,它允许我们指定要插入的远程文档的一部分。这是通过 url 参数的特殊语法实现的。如果字符串中包含一个或多个空格字符,则字符串中第一个空格后面的部分将被假定为 jQuery 选择器,用于确定要加载的内容。
$('#result').load('ajax/test.html #container');

This works for me :
这对我有用:
$.get(url,function(content) {
var content = $(content).find('div.contentWrapper').html();
...
}
