使用jQuery删除两个html标记之间的文本

I have the following HTML :

我有以下HTML:

<span>
<input type="text" value="0" size="10" class="element text currency" readonly="readonly" name="element_18_1" id="element_18_1"> .       
<label for="element_18_1">Dollars</label>
</span>

I would like to remove the dot between the input and the label tags using jQuery.

我想使用jQuery删除输入和标签标签之间的点。

I tried this code with no result : $('#element_18_1').contents(':gt(2)').remove(); Thanks

我尝试了这段代码没有结果:$('#element_18_1')。contents(':gt(2)')。remove();谢谢

5 个解决方案

#1

You could, however always choose an easier way, a simpler way, a clan slate readable and understandable way, a pure JavaScript way.

然而,您可以选择更简单的方式,更简单的方式,可靠且易懂的方式,纯粹的JavaScript方式。

element_18_1.nextSibling.data=" ";

element_18_1.nextSibling.data=" ";

<span>
<input type="text" value="0" size="10" class="element text currency" readonly="readonly" name="element_18_1" id="element_18_1"> .       
<label for="element_18_1">Dollars</label>
</span>

#2

This removes all texts which are not inside a tag (as element)

这将删除所有不在标记内的文本(作为元素)

$(document).ready(function(){
current = $('#element_18_1');
siblings = $('#element_18_1').siblings();
parent = $('#element_18_1').parent();
$(parent).html('');
$(parent).append(current).append(siblings);
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<span>
<input type="text" value="0" size="10" class="element text currency" readonly="readonly" name="element_18_1" id="element_18_1"> .       
<label for="element_18_1">Dollars</label>
</span>

You can make it shorter by joining some lines. I tried to show it step by step

你可以加入一些线来缩短它。我试着一步一步地展示它

#3

You can use contents() and slice(), i.e.:

你可以使用contents()和slice(),即:

var el1 = $("#element_18_1"), el2 = $("#element_18_1 + label"), contents = el1.parent().contents();
contents.slice(contents.index(el1) + 1, contents.index(el2)).remove();
el1.after(" ");

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span>
<input type="text" value="0" size="10" class="element text currency" readonly="readonly" name="element_18_1" id="element_18_1"> .       
<label for="element_18_1">Dollars</label>
</span>

#4

As stated here, I suggest to filter out the text node(s), and remove them:

如上所述,我建议过滤掉文本节点,然后删除它们:

$('span')
  .contents()
  .filter(function() {
    return this.nodeType == 3; //Node.TEXT_NODE
  }).remove();

See fiddle.

#5

This code is a bit crude but it should work

这段代码有点粗糙,但应该可行

$("span:contains('.')").html($("span:contains('.')").html().replace('.',''));
