有A、B两个页面
A页面有多个“修改”按钮,每个按钮有样式class="editbtn",点击ajax到B页面,如下代码
$(".editbtn").click(function(){ var url="b.php"; var params = $('form').serialize(); $.ajax({ url: url, type: 'post', dataType:'json', data: params, success: function (data){ $("#div1").html(data.html); $("#div2").html(data.script); } }); });
B页面
$data=array( 'html'=>$html, 'script'=>$script);echo json_encode($data);
B页面也会返回N条包含class="editbtn"的“修改”按钮,返回的这些按钮点击就无法完成$(".editbtn").click了,请问是什么原因呢?
之所以B页面有'script'=>$script,就是因为无法完成$(".editbtn").click事件,我又在B页面加了上面那段jquery,把它又弄到$("#div2").html,这样就可以运行,但是这样我感觉效率不好,好像如果点击了很多次就重复了很多次相同的代码,大神们觉得这样好吗?应该不好吧?
回复讨论(解决方案)
把 $(".editbtn").click(function(){
改为 $(document).on('click', ".editbtn", function(){
就可以了
把 $(".editbtn").click(function(){
改为 $(document).on('click', ".editbtn", function(){
就可以了
谢谢解答哈。
我之前是放在$(document).ready里面的,按照你说的我不管是放在这个内还是外提示:
TypeError: $(...).on is not a function
绑定事件改成
$('.clickme').live('click', function() {
alert("Live handler called.");
});
live:给所有匹配的元素附加一个事件处理函数,即使这个元素是以后再添加进来的也有效
把 $(".editbtn").click(function(){
改为 $(document).on('click', ".editbtn", function(){
就可以了
换了jquery版本可以了,之前用的jquery-1.6.2.min,改为jquery-1.8.3.min,谢谢,好多问题都是你回答解决的。
