如何在jquery中动态创建的元素上触发点击事件

问题描述：

if($('#term').children().length == 0){
        $("#term").append("<ul id='ulDynamic' class='ulDynamic'></ul>");
        var i;
        for(i=1;i<=3;i++){
            var liDynamic = "Term "+i;
            var liId = "Term"+i;
            $("#ulDynamic").append("<li id="+liId+ " class='listDynamic'>"+ liDynamic +"</li>");
                    if(i==0){
                       $('#'+liId).click();
        }
    }

.click动态创建的元素。我想要在页面加载时自动点击第一个li元素。有没有其他方法可以做到？

.click() is not working since liId is a dynamically created element. I want the first li element to be auto clicked when the page loads. Is there any other way to do it?

答

执行类似的操作：

$("#term").append("<ul id='ulDynamic' class='ulDynamic'></ul>");
        var i;
        for(i=1;i<=3;i++){
            var liDynamic = "Term "+i;
            var liId = "Term"+i;
            var $li = $("<li />", {
                "id" : liId,
                "class" : 'listDynamic'
            }).html(liDynamic).click(function() {
                alert("clicked:" + this.id);
            });

            $("#ulDynamic").append($li);            
        }
$("#ulDynamic").find("li:first").trigger("click");
