calling jquery function with anchor tag
提问by Arianule
I want to call a Jquery function with a hyperlink.
我想用超链接调用 Jquery 函数。
As I have it at the moment it is like this.
就像我现在拥有的那样。
<a name='lnkViews'>" + title+ "</a>
$("a[name='lnkViews']").on("click", function (e) {
alert("Calling function");
});
As it is here it is not working. How can I call the function with the Hyperlink?
因为它在这里它不起作用。如何使用超链接调用函数？

Use delegationversion of .on()for dynamic created element:
WORKING EXAMPLE
工作实例
$(document).on("click","a[name='lnkViews']", function (e) {
alert("Calling function");
});

Either Prevent Default Behavioror use the javascript:void(0)trick.
要么防止默认行为，要么使用javascript:void(0)技巧。
$(function() { // simply document onload call, just pointing out where to put code, if you didn't already know
$(document).on('click', 'a[name=lnkViews]', function(e) {
e.preventDefault();
});
})
| OR |
| 或 |
<a name="lnkViews" href="javascript:void(0);">" + title+ "</a>
then, in your JS
然后，在你的 JS 中
$(function() {
$(document).on('click', 'a[name=lnkViews]', function(e) {
/* do work */
});
})
I noticed in your comments you said the link is created dynamically, then my solution will work for you based on the fact I'm using the delegateversion of .on. What this means, is the event is assigned to anything added to the document that matches the selector. thus the reason for the assignment the way it is:
我在自己的评论注意到你说的是创建的链接dynamically，然后我的解决方案会为你根据我使用的事实工作delegate的版本.on。这意味着，事件被分配给添加到与选择器匹配的文档的任何内容。因此，分配的原因是这样的：
$(document).on('click', 'a[name=lnkViews]', function(e) {

Which version of jquery do you use?
你用的是哪个版本的jquery？
Put it into:
把它放入：
$(function()
{
js code
});
You've probably omitted it, but maybe it's not the thing because it looks you're adding link dynamically.
您可能已经省略了它，但也许不是，因为看起来您正在动态添加链接。
If so, try:
如果是这样，请尝试：
var link = "<a href='#' onclick='alert(\'Calling function\');'>" + title + "</a>";

You have to make sure that your a link is in the DOM when your on('click')code is executed.
当你的on('click')代码被执行时，你必须确保你的链接在 DOM 中。
The jQuery function on()will attach an event handler to all jQuery object contained in $("a[name='lnkViews']")but if there is no element matching "a[name='lnkViews']"in your DOM when $("a[name='lnkViews']").on()is executed no handler will be attached.
jQuery 函数on()会将事件处理程序附加到其中包含的所有 jQuery 对象，$("a[name='lnkViews']")但如果"a[name='lnkViews']"在$("a[name='lnkViews']").on()执行时您的 DOM 中没有匹配的元素，则不会附加任何处理程序。
To fix this you could do :
要解决此问题，您可以执行以下操作：
var $a = $('<a name="lnkViews">' + title+ '</a>');
$a.on("click", function (e) { });
//adding $a in your DOM with element.append($a); for exemple
You could also wait that your page is loaded before executing $("a[name='lnkViews']").on()by doing this :
您还可以$("a[name='lnkViews']").on()通过执行以下操作等待页面加载完毕后再执行：
$(function() {
$("a[name='lnkViews']").on("click", function (e) { });
});
