jQuery focus（）和blur（）对我的href不起作用。 为什么？

Question

i have a link in my html:

<a id="mnRoles" href="SysRoles.aspx">Roles</a>

here is more html:

<tr><td style="vertical-align:top;width:33%;">
<table cellpadding="0" cellspacing="0" class="MenuTable">
<tr><th>HRM</th></tr>
<tr><td><a id="mnRoles" href="SysRoles.aspx">Roles</a></td></tr>
<tr><td><a id="mnFunctions" href="SysFunctions.aspx">Function rights</a></td></tr>
<tr><td><a id="mnRegionalOptions" href="MenuCustomize.aspx">Regional options</a></td>    </tr>
</table></td></tr></table>

<script>sysPageUrl='logposmanagement.aspx'</script></form>

</body>
</html>

and i'm trying to set focus to it (or blur another one) through jQuery like this:

<script>
$(document).ready(function(){
    $("#mnRoles").blur();
    $("#mnFunction").focus();
});
</script>

but it doesn't work. any ideea why? thanks in advance!

(the reason i'm asking this: i want the focus to be set to a specific link of my choice when the page is loaded (through jQuery. i can't modify any html or css). could someone please help? thanks!)

Answer 1

Your link is:

<a id="mnFunctions" href="SysFunctions.aspx">Function rights</a>

Note that the id is mnFunctions , but in your jQuery code, you wrote:

$("#mnFunction").focus();

Here, the id is mnFunction . You omitted the s at the end. You must write this:

$(document).ready(function(){
    $("#mnRoles").blur();
    $("#mnFunctions").focus(); // note that the ID has an `s` at the end
});
