我有几个自定义标签的 HTML。我想找到除了两个('start','end')之外的所有东西并打开它们。jQuery.find() 似乎只在我搜索文档中的内容时才找到这些自定义标签,而不是在我搜索 jQuery 对象时。我究竟做错了什么?
在小提琴中应该是不言自明的:
这是javascript部分:
var raw = $('pre').html();
var html = $(raw);
var starts = html.find('start');
var spans = html.find('span');
//this returns nothing
console.log(starts)
// works - can find in object
console.log(spans)
//this works
console.log($('start'));
//only picks up spans, not annotations
// I want this to return the innerHTML of the pre, stripping all tags except for 'start' and 'end' -- but retain the contents of those tags.
var cleaned = html.find(':not(start, end)').each(function() {
$(this).contents().unwrap();
});
console.log(cleaned);
$('#clean').html(cleaned)
和 HTML 的一个例子:
<span class="ng-scope">CTAGCTCTCTGGAGATTAACGAGGAGAAATACTAGAtTGGTTCAT</span>
<start feat="1" class="ng-scope"></start>
<annotation index="1" class="ng-isolate-scope ng-scope" style="background-color: rgb(238, 153, 238); background-position: initial initial; background-repeat: initial initial;">
<span tooltip="Another Promoter" tooltip-placement="mouse" tooltip-append-to-body="true" ng-transclude="" class="ng-scope">
<span class="ng-scope">GATCATAAgcttgaat</span>
</span>
</annotation>
<end feat="1" class="ng-scope"></end>
<span class="ng-scope">tagccaaacttatt</span>
应该是:
CTAGCTCTCTGGAGATTAACGAGGAGAAATACTAGAtTGGTTCAT<start feat="1" class="ng-scope"></start>GATCATAAgcttgaat<end feat="1" class="ng-scope"></end>tagccaaacttatt
谢谢
