Passing a variable to a selector: Syntax Error

in Using jQuery • 9 years ago

I'm new to JQuery and have been searching the internet for help passing a variable to a selector. I have found a few resources and tried to implement them but they're just not working for me. I am trying to find href that match my variable and am working with the following:

var itemLink = /site/Mario-Kart..etc.

$("a[href=" + itemLink + "]").......etc.

I receive an error "Uncaught Syntax Error unrecognized expression: [href=/site/Mario-Kart..etc. ]"

I have been placing the quotes in different places to correct the syntax but to no avail. Also, this works with JQuery v1.44 and earlier but not after.

I have a feeling it's a simple fix, but I'm just missing it. Any help would be appreciated.

Thanks.

As you've noted you need to include quotes around the attribute value. Try this - alternating between single and double quotes:

$('a[href="' + itemLink + '"]')...

I gave it a try, alternating single and double quotes, but it still gives the same error...any other thoughts? It still works in version 1.4.4 but not in 1.6.2

Can you post the full lines from your current attempt?

Here's the script I am trying to execute. The "MyChosenURL" is any url I am trying to match on a webpage. I'm trying to find all the links and then go through each link to find a match to the URL. From what I can tell, Line 8 stops the function with the error I posted above. Again, this works in v1.4.4 but it doesn't for the newer versions of JQuery and I can't figure out why.

Thanks for all your help

regards

var itemLink = MyChosenURL;
var allHref = {};
allLinks = $('a[href]').each(function() {
allHref[$(this).attr('href')] = true;
});
$.each(allHref, function() {
$('a[href="' + itemLink + '"]').each(function(i) {
if (i == 1) {
itemTitle = $(this).text();
return false ;
}
});
});
alert(itemTitle);
