The click event is triggered, but you haven't bound a click handler so nothing will happen. If you want to simulate clicking the link you need to use the dom click method, ie. $('#SHOW_HELP')[0].click();

点击事件被触发,但你没有绑定点击处理程序所以什么都不会发生。如果要模拟单击链接,则需要使用 dom click 方法,即。$('#SHOW_HELP')[0].click();

It's actually working.

它实际上在起作用。

Here a JSFiddle example: http://jsfiddle.net/rZbk7/

这里有一个 JSFiddle 示例:http: //jsfiddle.net/rZbk7/

$('#info').on('click', function(e) {
   alert("info triggered");
   $('#show-help').click();
});

$('#show-help').on('click', function(e) {
   alert("show-help triggered");
});

(not a big fun of snake case, I changed the name SHOW_HELP to show-help)

(蛇案没有太大的乐趣,我将名称 SHOW_HELP 更改为 show-help)

Click event is triggered. The problem is that you didn't define any action.

点击事件被触发。问题是您没有定义任何操作。

Alternatively, you can update the button's click event to change the window.locationin JavaScript.

或者,您可以更新按钮的单击事件以更改window.locationJavaScript。

Try this:

试试这个:

$(function(){
    $('#info').click(function(){
        window.location = $('#SHOW_HELP').attr('href');
    });
});

$('#SHOW_HELP').bind('click', function(e) {
        alert ("button click triggered");
// This is what I tried so fat

 //$('#SHOW_HELP').trigger('click');
 //$('#SHOW_HELP').dispatchEvent(new Event('click'));

});
