我有一个在div内生成的删除按钮。单击时,我希望它删除自身和div及其中的所有内容。
$('#geography-save').click(function () {
$('.selected-criteria').prepend('<div><button type="button" class="btn btn-danger remove-save"><i class="fa fa-times"></i></button><p>Geography Selection</p></div>');
});
$(document).ready(function(){
$('.remove-save').on('click', function () {
alert('test');
$(this).parent('div').remove();
});
});

<button type="button" class="btn btn-success" id="geography-save" data-dismiss="modal">Save Search</button>
<div class="selected-criteria"></div>

只需使用jQuery的on()
方法:
$('body').on('click', '.remove-save', function () { ... });
如果内容是在DOM结构中动态生成的,那么您应该将事件绑定到已存在的父级!
$('#geography-save').click(function () {
$('.selected-criteria').prepend('<div><button type="button" class="btn btn-danger remove-save"><i class="fa fa-times"></i></button><p>Geography Selection</p></div>');
});
$(document).ready(function(){
$('body').on('click', '.remove-save', function () {
alert('test');
$(this).parent('div').remove();
});
});

由于您button
是动态生成的,因此您只能基于 static 元素访问它 - 所以您可以使用它:
$('body').on('click','.remove-save', function () {
见下面的演示:
$('#geography-save').click(function() {
$('.selected-criteria').prepend('<div><button type="button" class="btn btn-danger remove-save"><i class="fa fa-times"></i></button><p>Geography Selection</p></div>');
});
$(document).ready(function() {
$('body').on('click', '.remove-save', function() {
$(this).parent('div').remove();
});
});
