我的页面上有这个HTML:
<div class="phrase">
<ul class="items">
<li class="agap"><ul><li>TEXT1</li></ul></li>
<li class="agap"><ul> </ul></li> <!-- empty ul -->
<li class="aword">TEXT2</li>
..
</ul>
</div>
<div class="phrase"> ... </div>
我想为每个“短语”获取文本变量中“items”中的所有元素,如下所示:
var string = "TEXT1 - BLANK - TEXT2";
我目前有这个javascript代码:
<script>
$(function() {
$('.phrase .items').each(function(){
var myText = "";
// At this point I need to loop all li items and get the text inside
// depending on the class attribute
alert(myText);
});
};
</script>
如何迭代<li>
内的所有.items
?
我尝试了不同的方法,但结果并不好。

首先,我认为您需要修复列表,因为<ul>
的第一个节点必须是<li>
(stackoverflow ref)。设置完成后,您可以执行以下操作:
// note this array has outer scope
var phrases = [];
$('.phrase').each(function(){
// this is inner scope, in reference to the .phrase element
var phrase = '';
$(this).find('li').each(function(){
// cache jquery var
var current = $(this);
// check if our current li has children (sub elements)
// if it does, skip it
// ps, you can work with this by seeing if the first child
// is a UL with blank inside and odd your custom BLANK text
if(current.children().size() > 0) {return true;}
// add current text to our current phrase
phrase += current.text();
});
// now that our current phrase is completely build we add it to our outer array
phrases.push(phrase);
});
// note the comma in the alert shows separate phrases
alert(phrases);
工作jsfiddle。
有一件事是,如果你得到上层.text()
的{{1}},你将获得所有子级文本。
保持数组将允许提取多个短语。

如果空li
没有UL

LI

$(function() {
$('.phrase .items').each(function(i, items_list){
var myText = "";
$(items_list).find('li').each(function(j, li){
alert(li.text());
})
alert(myText);
});
};

给出较高的投票率和观点。我确实找到了包含此处链接和其他链接的答案。
我有一个方案,如果未选择患者,则所有与患者相关的菜单都将被禁用。 (请参阅链接-how to disable a li tag using JavaScript)
//css
.disabled{
pointer-events:none;
opacity:0.4;
}
// jqvery
$("li a").addClass('disabled');
// remove .disabled when you are done
因此,我没有编写冗长的代码,而是通过CSS找到了一个有趣的解决方案。
$(document).ready(function () {
var PatientId ;
//var PatientId =1; //remove to test enable i.e. patient selected
if (typeof PatientId == "undefined" || PatientId == "" || PatientId == 0 || PatientId == null) {
console.log(PatientId);
$("#dvHeaderSubMenu a").each(function () {
$(this).addClass('disabled');
});
return;
}
})
.disabled{
pointer-events:none;
opacity:0.4;
}
