我创建了一个动态列表视图, 我想从列表视图中的行中获取数据, 我点击该行( 数据显示在列表视图上, 因此附件工作完美), 当我单击并尝试将数据输入到“ x” 时, 我就会得到“ 未找到 ”, 我不明白原因!
我的代码:
for (var i = 0; i < json_parsed.Categories.length; i++){
var cars= json_parsed.Categories[i];
$( #categoryList ).append($( <li data-categoryId = cars.car_name> ).html( <a href="#" onclick = "temp()" > +cars.car_name+</a> ));
}
function temp () {
var x = $(this).data( categoryId );
alert (x);
};
HAHAHAHAHAU 前的
由于您正在使用 jQuery, 您可以在下面绑定 点击 事件 。
$( #categoryList ).on( click , li , function () {
var x = $(this).data( categoryId );
alert(x);
});
var cars;
for (var i = 0; i < json_parsed.Categories.length; i++){
cars = json_parsed.Categories[i];
$( #categoryList ).append( <li data-categoryId=" + cars.car_name + "><a href="javascript:void(0)" > +cars.car_name + </a> );
}
$( #categoryList ).on( click , li , function () {
var x = $(this).data( categoryId );
alert(x);
});
<强>编辑:
我加入我的代码!
你忘了提到你正在使用jQuery 1.6.4版本。
不管怎样 点击处理器会像下面一样更改,
$( #categoryList ).delegate( li , click , function() {
var x = $(this).data( categoryid );
alert(x);
});
然而,jQuery建议()在(jQuery 1. 7+.
您需要使用现场活动, 即一个事件Handler, 它将与元素绑在一起, 这些元素不是在页面加载时创建的, 而是以后创建的 。
