Question

我有一个格式化的文本字段，其中包含..

"this is some text node&nbsp;
<div class="myClass">contents....</div>
&nbsp;some more text node&nbsp;
<div class="myClass">contents....</div>
&nbsp;"

像这样。

现在我要移除所有周围的＆＃34; &nbsp＆＃34;对那些只有class="myClass"的那些div，即＆＃34; &nbsp＆＃34;在那些div之前和之后。

我已经通过了这个链接，但它没有解决我的问题

提前致谢。

Answer 1

我可能会选择像

这样的东西

var text = '"this is some text node&nbsp;<div  class="myClass"> contents....</div>&nbsp;some more text node&nbsp;<div  class="myClass"> contents.... </div>&nbsp;"';

var $ct = $('<div />', {
    html: text
});

$ct.find('.myClass').each(function () {
    if (this.nextSibling && this.nextSibling.nodeType == 3) {
        this.nextSibling.data = this.nextSibling.data.replace(/^\s+/, '');
    }
    if (this.previousSibling && this.previousSibling.nodeType == 3) {
        this.previousSibling.data = this.previousSibling.data.replace(/\s+$/, '');
    }
})

var html = $ct.html();

演示：Fiddle

Answer 2

你可以替换＆＃39;＆＃39;而不是＆＃39;＆amp; NBSP;＆＃39;，

$('.myClass').html($('.myClass').html().replace('&nbsp;',''));

或尝试这样，

$('.myClass').html(function(i,h){
return h.replace(/&nbsp;/g,'');});

Answer 3

var text = '"this is some text node&nbsp;&nbsp; <div  class="myClass"> contents....</div> &nbsp;&nbsp;"';    
var $ct;
$ct = $('<pre />', {
    html: text
});

$ct.find('.myClass').each(function () {
    if (this.nextSibling && this.nextSibling.nodeType == 3) {        
        var r = this.nextSibling.data;
        this.nextSibling.data = this.nextSibling.data.replace(String.fromCharCode(160), '');
        var s = this.nextSibling.data;
        this.nextSibling.data = this.nextSibling.data.replace(/^&nbsp;/, '');
    }
    if (this.previousSibling && this.previousSibling.nodeType == 3) {
        this.previousSibling.data = this.previousSibling.data.replace(String.fromCharCode(160), '');
        this.previousSibling.data = this.previousSibling.data.replace(/&nbsp;/, '');
    }
})

var html = $ct.html();
alert(html);

感谢所有人。我刚刚修改了Arun P johny先生的代码。这对我来说非常有用。在他的代码中它也删除了空格，但我想删除＆amp; nbsp only。
