Anchor tag jQuery Click
提问by Suave Nti
I have an Anchor Tag like this
我有一个这样的锚标签
<a href="javascript:anchorScr()" id="anch1" class ="af-link"/>
It is taking me two clicks on the anchor tag to respond to the javascript function anchorScr();
我需要在锚标记上单击两次才能响应 javascript 函数 anchorScr();
function anchorScr() {
jQuery('a').click(function (event) {
var id = $(this).attr("id");
alert(id);
});
}
Am I doing something wrong? Why my anchorScr() is not called on the first click ?
难道我做错了什么？为什么我的 anchorScr() 在第一次点击时没有被调用？

This calls the anchorScrfunction when the anchor is clicked:
anchorScr单击锚点时调用该函数：
href="javascript:anchorScr()"
The function then attaches a clickevent handler to all aelements.
然后该函数将一个click事件处理程序附加到所有a元素。
Remove the hrefand just have this:
删除href并只有这个：
jQuery('a').click(function (event) {
var id = $(this).attr("id");
alert(id);
});
The code will execute - attaching the clickevent handler to all aelements. You should probably only run this on ready()to ensure that the page has fully loaded into the DOM.
代码将执行 - 将click事件处理程序附加到所有a元素。您可能应该只运行它ready()以确保页面已完全加载到 DOM 中。

<a href="#" id="anch1" class ="af-link">click here</a>
jQuery(document).ready(function(){
jQuery('a').click(function (event) {
var id = $(this).attr("id");
alert(id);
});
});
