Javascript jquery:anchor类多次单击激发
我不熟悉jquery。我希望在单击锚时克隆一个具有新id的div。但是当我单击锚元素时,div被克隆了多次 代码: htmlJavascript jquery:anchor类多次单击激发,javascript,jquery,html,onclick,Javascript,Jquery,Html,Onclick,我不熟悉jquery。我希望在单击锚时克隆一个具有新id的div。但是当我单击锚元素时,div被克隆了多次 代码: html html+='<li><a data-role="button" class="km-widget km-button cls-delete" type="button" id="'+del_id+'" ><span class="km-text">delete</span></a> &

html+='删除复制编辑 ';
我哪里做错了?如何解决此问题?找到了解决方案:
$(document).ready(function(){
$("a.cls-copy").unbind('click').bind("click", function(event){
alert("test");
event.stopPropagation();
div_id = $(this).closest('div').attr('id');
var newdiv = $("#"+div_id).clone(true).attr('id',"newQuestionsDiv-Page"+countPage+"-"+questionCount).insertAfter("#"+div_id);
console.log("newdiv : "+$(newdiv).attr('id'));
if($(newdiv).find(".questiondata").length != 0)
{
$(newdiv).find(".questiondata").val("");
}
e_id = "edit"+countPage+"-"+questionCount;
var temp_id= $(newdiv).attr('id');
d_id = "del"+countPage+"-"+questionCount;
c_id = "copy"+countPage+"-"+questionCount;
questionCount++;
showSuccessToast("Your question is copied");
$("#"+temp_id).find(".cls-edit").attr('id',e_id);
$("#"+temp_id).find(".cls-delete").attr('id',d_id);
$("#"+temp_id).find(".cls-copy").attr('id',c_id);
});
});
Replace your code with above code and check how much time test alerts ..
$(document).off("click","a.cls-copy").on("click", "a.cls-copy", function(event){
event.stopPropagation();
div_id = $(this).closest('div').attr('id');
var newdiv = $("#"+div_id).clone(true).attr('id',"newQuestionsDiv-Page"+countPage+"-"+questionCount).insertAfter("#"+div_id);
console.log("newdiv : "+$(newdiv).attr('id'));
if($(newdiv).find(".questiondata").length != 0)
{
$(newdiv).find(".questiondata").val("");
}
e_id = "edit"+countPage+"-"+questionCount;
var temp_id= $(newdiv).attr('id');
d_id = "del"+countPage+"-"+questionCount;
c_id = "copy"+countPage+"-"+questionCount;
questionCount++;
showSuccessToast("Your question is copied");
$("#"+temp_id).find(".cls-edit").attr('id',e_id);
$("#"+temp_id).find(".cls-delete").attr('id',d_id);
$("#"+temp_id).find(".cls-copy").attr('id',c_id);
});
有了这个代码
1) .on-您可以向DOM中添加元素,但仍可以处理单击事件
2) .off-删除事件处理程序
请参阅它可以正常工作,但对我来说不行。如果我向DOM树动态添加更多元素,那么这将不起作用。如何解决此问题?用on和test替换bind
$(document).off("click","a.cls-copy").on("click", "a.cls-copy", function(event){
event.stopPropagation();
div_id = $(this).closest('div').attr('id');
var newdiv = $("#"+div_id).clone(true).attr('id',"newQuestionsDiv-Page"+countPage+"-"+questionCount).insertAfter("#"+div_id);
console.log("newdiv : "+$(newdiv).attr('id'));
if($(newdiv).find(".questiondata").length != 0)
{
$(newdiv).find(".questiondata").val("");
}
e_id = "edit"+countPage+"-"+questionCount;
var temp_id= $(newdiv).attr('id');
d_id = "del"+countPage+"-"+questionCount;
c_id = "copy"+countPage+"-"+questionCount;
questionCount++;
showSuccessToast("Your question is copied");
$("#"+temp_id).find(".cls-edit").attr('id',e_id);
$("#"+temp_id).find(".cls-delete").attr('id',d_id);
$("#"+temp_id).find(".cls-copy").attr('id',c_id);
});
