我怎样才能增加特定的课程?
我正在使用克隆方法,我已经成功克隆了Id并增加了它.但我想在我正在增加的Div中增加我的课程.
我的课程增量:.emptybox
我的js:
//duplicate Play Timer
var i = 0;
var original = document.getElementById('Play_Start');
var count = 1;
function duplicatePlay() {
if (count < 20) {
var clone = original.cloneNode(true); // "deep" clone
clone.id = "Play_Start" + ++i; // there can only be one element with an ID
original.parentNode.appendChild(clone);
$(clone).effect( "highlight", {color:"#FEFFB9"}, 3000 );
count++;
} else {
}
}
最佳答案 你可以做这样的事情
var i = 0;
var original = document.getElementById('Play_Start');
var count = 1;
function duplicatePlay() {
if (count < 20) {
var clone = original.cloneNode(true); // "deep" clone
clone.id += ++i; // there can only be one element with an ID
clone.querySelector('.emptybox').className = 'emptybox' + i;
original.parentNode.appendChild(clone);
$(clone).effect("highlight", {
color: "#FEFFB9"
}, 3000);
count++;
} else {}
}
duplicatePlay();
<div id="Play_Start" class="abc cde">hi <span class="emptybox">user</span>
</div>
