<pre><code>$(someElement).trigger('click');

blocks|key|973419|text|只需使用click()|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|973420|$(selector).click();|code-block|syntax|javascript|973421|或者，也可以将您的click()代码移出到一个公共函数中，然后从hover()调用它。|style|CODE|973422|entityMap|0|LINK|mutability|MUTABLE|url|http://api.jquery.com/click/^0|4|5|0|0|0|9|7|W|7|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|F|7|Y|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|Z|8|@$A|10|B|11|K|L]|$A|12|B|13|K|L]]|9|@]|C|$]]|$1|M|3|-4|5|6|7|14|8|@]|9|@]|C|$]]]|N|$O|$5|P|Q|R|C|$S|T]]]]

Just use <a href="http://api.jquery.com/click/" rel="noreferrer">click</a>()

<pre><code>$(selector).click();

Or, alternatively just move your <code>click()</code> code out into a common function and call that from <code>hover()</code>.

EDIT: way later than the post but just to illustrate how to both add the handler AND trigger it.

<pre><code>$('myselector').on('click',function(){ 
 // handle click event, put money in my bank account 
}).on('mouseenter',function(){ 
 $(this).trigger('click'); // only on enter here
 // handle hover mouse enter of hover event, put money in my bank account 
}).on('mouseleave',function(){ 
 // handle mouse leave event of hover, put money in my bank account 
}).trigger('click');
</code></pre>

Just need it one time?

<pre><code>$('myselector').on('click',function(){ 
 // handle click event, put money in my bank account 
}).one('mouseenter',function(){ 
 $(this).trigger('click'); // only on enter here once
 // handle hover mouse enter of hover event, put money in my bank account 
}).on('mouseenter',function(){ 
 // handle hover mouse enter of hover event, put money in my bank account 
}).on('mouseleave',function(){ 
 // handle mouse leave event of hover, put money in my bank account 
});
</code></pre>

It is possible to trigger a click event on hover.

Try the following example:

<pre><code>&lt;!doctype html&gt;
&lt;html lang="en"&gt;
&lt;head&gt;
 &lt;meta charset="utf-8"&gt;
 &lt;title&gt;hover + (mouseup/mousedown, click) demo&lt;/title&gt;
 &lt;script src="http://code.jquery.com/jquery-1.10.2.js"&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;p class="up"&gt;Press mouse and release here.&lt;/p&gt;
&lt;p class="hover1"&gt;Press mouse and release here. HOVER+UP/DOWN&lt;/p&gt;
&lt;p class="hover2"&gt;Press mouse and release here. HOVER.UP/DOWN&lt;/p&gt;
&lt;p class="hover3"&gt;Press mouse and release here. HOVER.CLICK&lt;/p&gt;

&lt;script&gt;
$( "p.up" )
 .mouseup(function() {
 $( this ).append( "&lt;span style='color:#f00;'&gt;Mouse up.&lt;/span&gt;" );
 })
 .mousedown(function() {
 $( this ).append( "&lt;span style='color:#00f;'&gt;Mouse down.&lt;/span&gt;" );
 });
$( "p.hover1" )
 .hover(
 function() {
 $( this ).append( "&lt;span style='color:#f00;'&gt;Hover IN.&lt;/span&gt;" );
 },
 function() {
 $( this ).append( "&lt;span style='color:#00f;'&gt;Homer OUT.&lt;/span&gt;" );
 })
 .mouseup(function() {
 $( this ).append( "&lt;span style='color:#f00;'&gt;Mouse up.&lt;/span&gt;" );
 })
 .mousedown(function() {
 $( this ).append( "&lt;span style='color:#00f;'&gt;Mouse down.&lt;/span&gt;" );
 });
$( "p.hover2" )
 .hover(
 function() {
 $( this ).append( "&lt;span style='color:#f00;'&gt;Hover IN.&lt;/span&gt;" );
 },
 function() {
 $( this ).append( "&lt;span style='color:#00f;'&gt;Homer OUT.&lt;/span&gt;" );
 });
$( "p.hover2" )
 .mouseup(function() {
 $( this ).append( "&lt;span style='color:#f00;'&gt;Mouse up.&lt;/span&gt;" );
 })
 .mousedown(function() {
 $( this ).append( "&lt;span style='color:#00f;'&gt;Mouse down.&lt;/span&gt;" );
 });
$( "p.hover3" )
 .hover(
 function() {
 $( this ).append( "&lt;span style='color:#f00;'&gt;Hover IN.&lt;/span&gt;" );
 },
 function() {
 $( this ).append( "&lt;span style='color:#00f;'&gt;Homer OUT.&lt;/span&gt;" );
 });
$( "p.hover3" )
 .click(function() {
 $( this ).append( "&lt;span style='color:#00f;'&gt;CLICK.&lt;/span&gt;" );
 });
&lt;/script&gt;

&lt;/body&gt;
&lt;/html&gt;

You might want to also add a delay on hover so that it won't immediately trigger. Delay will be useful if you are going to use it in a list of thumbnails.

<pre><code>var hoverTimer;
var hoverDelay = 200;

$('.classSelector').hover(function() {
 var $target = $(this);
 // on mouse in, start a timeout
 hoverTimer = setTimeout(function() { 
 // do your stuff here
 $target.trigger('click'); 
 }, hoverDelay);
}, function() {
 // on mouse out, cancel the timer
 clearTimeout(hoverTimer);

});
</code></pre>

General javascript question here, which would also be good to know how(if possible) to do in jquery.

Can you trigger a click event when hovering over an item?

I know there will be people asking why, but please just humour me.

Many thanks,
C

一般的javascript问题在这里，这也将是很好的知道如何(如果可能)在jquery做。当鼠标悬停在某个项目上时，是否可以触发单击事件？我知道会有人问为什么，但请迁就我。非常感谢，C
