I am reading data from a json file. The div with 'box' class is hidden. Currently this code is displaying all div on click of the li. What changes should I make to display only the div corresponding to the clicked li?

Here what we need to do is to find the .box
element within the clicked li
, so we need to get a reference to the clicked element.
这里我们需要做的是在被点击的li中找到.box元素,因此我们需要获得对被点击元素的引用。
I would use a delegated jQuery event handler with css to initially hide the element
我将使用委托的jQuery事件处理程序与css最初隐藏元素
$(document).ready(function () {
$('#newsDetails').on('click', 'li', function () {
$(this).find('.box').toggleClass('hidden');
})
$.getJSON("js/JobOpenings.json", function (data) {
var glrScrlImg = [];
$.each(data.getJobOpeningsResult, function (key, val) {
var st = "",
id, st2 = "",
st3 = "",
id;
st += "<h4>" + val.JobTitle + "</h4>";
st3 += "<div class='box hidden'>" + val.JobDetails + "</div>";
$("#newsDetails").append("<li>" + st + val.JobSector + "<br>" + st3 + "</li>");
});
});
});
with css
.hidden {
display: none;
}

Pass the control to the function and then based on your control slideToggle
its respective .box
将控件传递给该函数,然后根据您的控件slideToggle其各自的.box
function demo(ctrl){
$(ctrl).find('.box').slideToggle('fast');
}
$(document).ready(function(){
$.getJSON( "js/JobOpenings.json", function( data ) {
var glrScrlImg = [];
$.each( data.getJobOpeningsResult, function( key, val ) {
var st = "",id,st2= "",st3="",id;
st +="<h4>" + val.JobTitle + "</h4>";
st3 += "<div class='box'>" + val.JobDetails + "</div>";
$("#newsDetails").append("<li onclick='demo(this)'>" + st+val.JobSector + "<br>" + st3 + "</li>");
$('.box').hide();
});
});
});
Or add a class to li
and attach an event handler like below instead of writing inline onclick
as below:
或者向li添加一个类并附加一个如下所示的事件处理程序,而不是如下所示编写内联onclick:
$("#newsDetails").append("<li class="someclass"'>" + st+val.JobSector + "<br>" + st3 + "</li>");
and then instead of function demo()
write this
然后代替函数demo()写这个
$('#newsDetails').on('click','.someclass',function(){
$(this).find('.box').slideToggle('fast');
});
UPDATE
Method 1:
function demo(ctrl){
$('#newsDetails').find('li.box').hide('fast'); //hide all the .box
$(ctrl).find('.box').slideToggle('fast');
}
Method 2:
$('#newsDetails').on('click','.someclass',function(){
$('#newsDetails').find('li.box').hide('fast'); //hide all the .box
$(this).find('.box').slideToggle('fast');
});
UPDATE 2:
Method 1:
function demo(ctrl){
$('#newsDetails').find('li.box').not($(ctrl).find('.box')).hide('fast'); //hide all the .box
$(ctrl).find('.box').slideToggle('fast');
}
Method 2:
$('#newsDetails').on('click','.someclass',function(){
$('#newsDetails').find('li.box').not($(ctrl).find('.box')).hide('fast'); //hide all the .box except this
$(this).find('.box').slideToggle('fast');
});

You should structure your html (which is missing from the question!) so that the div and li are "connected" in some way (maybe the div is child of li, or they have same class, ecc). Right now the line
你应该构造你的html(问题中缺少这个!),以便div和li以某种方式“连接”(也许div是li的子,或者他们有相同的类,ecc)。现在就行
$('.box').slideToggle('fast');
is applied to all element with class '.box' in your page. You want to be more selective there, that's where the way you structure the html comes into play.
应用于页面中具有类“.box”的所有元素。你希望在那里更有选择性,那就是你构建html的方式发挥作用。
