我有以下span元素:
<div class="text" contenteditable="true" id="example">
<div class="outside">Type here <span class="inside"> please</span>.</div>
<div class="outside">Name here <span class="inside"> first </span>name</div>
</div>
使用以下js函数,我可以得到</span>
和</div>
之间的长度:
$('span.inside').each(function() {
var sphs = $(this).get(0).nextSibling;
var len = sphs.length;
//If the length is less than 2
if(len < 2){
// i want to replace it with another words like "thanks."
}
})
如果长度小于8,那么我想将其替换为其他字词或字符串(例如,thanks.
)IN BETWEEN </span>
和</div>
(请参阅“谢谢“安置”。
<div class="text" contenteditable="true" id="example">
<div class="outside">Type here <span class="inside"> please</span>thanks.</div>
</div>
我如何用另一个字符串替换它?
修改
请注意,我使用的是.each
,因为可能存在多个具有相同类名的span元素。在第一行中,只有一个句点(</span>.</div>
),因此它满足条件并将被替换为另一个单词(在本例中为“thanks”)。
在第二行(</span>name</div>
)中,长度大于2,因此不会被替换。
我希望这能澄清它。
<div class="text" contenteditable="true" id="example">
<div class="outside">Type here <span class="inside"> please</span>.</div>
<div class="outside">Name here <span class="inside"> first </span>name</div>
</div>
......将成为......
<div class="text" contenteditable="true" id="example">
<div class="outside">Type here <span class="inside"> please</span> thanks.</div>
<div class="outside">Name here <span class="inside"> first </span>name</div>
</div>

$('span.inside').each(function() {
var sphs = $(this).get(0).nextSibling;
var len = sphs.length;
//If the length is less than 2
if(len < 2){
// DOM method:
sphs.textContent = ' Thanks.';
// jQuery method:
$(this).parent().get(0).childNodes[2].textContent = ' Thanks.';
}

添加额外(空)范围并进行设置。它就像设置范围的text()一样简单。
<强> HTML:强>
<div class="text" contenteditable="true" id="example">
<div class="outside">Type here <span class="inside"> please</span><span id="extra"></span></div>
</div>
<强> JS:强>
//If the length is less than 2
if(len < 2){
$('span#extra').text("thanks.");
}
