我希望在关键时改变可折叠1 的颜色,或者在txt1,txt2上键入可折叠2
<div class="panel-group" id="accordion">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
Collapsible 1
</a>
</h4>
</div>
<div id="collapseOne" class="panel-collapse collapse in">
<div class="panel-body">
<section>
<div class="section_inner">
<input type="text" name="txt1" id="txt1" class="required"/>
<input type="text" name="txt2" id="txt2" class="required"/>
</div>
</section>
</div>
</div>
</div>
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">
Collapsible Group Item #2
</a>
</h4>
</div>
<div id="collapseTwo" class="panel-collapse collapse">
<div class="panel-body">
<section>
<div class="section_inner">
<input type="text" name="txt3" class="required"/>
<input type="text" name="txt4" class="required"/>
<input type="text" name="txt5" class="required"/>
<input type="text" name="txt6"/>
</div>
</section>
</div>
</div>
</div>
</div>
我已经尝试但是它不在这里工作是我的代码,我怎么能这样做?
var collapseOne = 0;
//collapseOne reqeried validation
$('#collapseOne input[type=text]').keyup(function(e){
$('#collapseOne input[type=text]').each(function(){
if ( $(this).hasClass('required') ){
if ( $(this).val() != '' ){
collapseOne = 1;
}
}
});
if ( collapseOne == 1 ){
$("h4").find("a").css("color","green");
//$(this).find("data-id='collapseOne'").css("color","green");
//$(this).closest('.panel-heading h4').css("color","green");
}
});
答案 0 :(得分:2)
您正在检查:
if ( $(this).hasClass('required') )
$(this)
在这里引用带有类required
但是,在HTML标记中,您没有使用类required
输入任何内容,请尝试添加:
<input type="text" name="txt1" id="txt1" class="required" />

如果您想根据以下输入定位H4,您可以使用:
$(this).closest('#collapseOne').siblings('.panel-heading').find('h4 a').css("color","green");
这里不需要if

好的,这是最终解决方案:
var collapseOne = 0;
$('#collapseOne input[type=text]').keyup(function (e) {
var h4Text = $(this).closest('#collapseOne').siblings('.panel-heading').find('h4 a');
$('#collapseOne input[type=text]').each(function () {
if ($(this).hasClass('required')) {
if ($(this).val() != '') {
collapseOne = 1;
} else {
collapseOne = 0;
}
}
});
if (collapseOne == 1) {
h4Text.css("color", "green");
} else {
h4Text.css("color", "")
}
});
