[英]Add styling on click with dynamically created DOM elements
我想在選中div內包含的圖像周圍創建邊框,然后在取消選中它時將其刪除。 如何獲取所選div的ID?
function displayLive()
{
var previous = null;
var current = null;
setInterval(function()
{
$.ajax({
url: '/showLive',
dataType: 'json',
contentType: 'application/json',
success: function(response)
{
current = JSON.stringify(response);
if(previous !== current)
{
var obj = JSON.parse(response);
console.log(obj);
for(var i = 0; i < obj.active.length; i++)
{
if($(document.getElementById(obj.active[i].userNameData)).length == 0)
{
if(obj.active[i].active === true)
{
$('.left').prepend($('<div/>', {class: 'profTemp', id: obj.active[i].userNameData}).append(
$('<img/>', {src: obj.active[i].profiler, width: 40, height: 40}),
$('<span/>', {text: " " + obj.active[i].userNameData})));
}
}
else if(obj.active[i].active === false)
{
$(document.getElementById(obj.active[i].userNameData)).remove();
console.log("getting in false");
}
}
}
}
});
previous = current;
}, 2000);
}
通過$(document).on('click', '.profTemp', function() {})
分配點擊處理程序$(document).on('click', '.profTemp', function() {})
以觸發文檔上的click事件,以便它將與動態添加的元素一起使用,然后在div並將其用作是否單擊狀態,並引用該類以繪制邊框。
$('body').append('<div class="profTemp"> <img class="img" src="https://i.stack.imgur.com/2C22p.jpg"></div>'); $(document).on('click','.profTemp',function() { $(this).toggleClass('selected'); })
.profTemp { display: inline-block; } .selected img { border: 5px solid red; }
