I am trying to make jquery trigger an event when an anchor link has the same URL as the current page. Eventually this will add a class to the anchor link and let me style it differently with CSS but for now I just want it to show an alert box. Code below doesn't seem to work:
<script type="text/javascript">
$(document).ready(function() {
var buildurl = window.location.href;
if($('a').attr('href') = buildurl){
alert("Done");
}
});
</script>
Can anybody shine a light on why this isn't working? Or a best practice for similar using JQuery?

<script type="text/javascript">
$(document).ready(function() {
var buildurl = window.location.href;
if($('a').attr('href') == buildurl){
alert("Done");
}
});
</script>
use equality operator ==
if($('a').attr('href') == buildurl){
alert("Done");
$('a').attr("color","Red");
}
You have an assignment in your if condition. You need to add one = to it.
<script type="text/javascript">
$(document).ready(function() {
var buildurl = window.location.href;
if($('a').attr('href') == buildurl){
alert("Done");
}
});
</script>

This may be a really dumb question but I'm having trouble including a jquery plugin in my code.
The plugin I'm referring to is: http://davidlynch.org/projects/maphilight/docs/
I want to mimic something very similar to the following:
http://jsfiddle.net/keith/PVpgK/
But when I copy the code over, I keep getting error messages saying "maphilight is not a function"
How do I use a jquery plugin in my code? Thank you
$(function() {
//using the jquery map highlight plugin:
//http://davidlynch.org/js/maphilight/docs/
//initialize highlight
$('.map').maphilight({strokeColor:'808080',strokeWidth:0,fillColor:'00cd27'});
//hover effect
$('#maplink1').mouseover(function(e) {
$('#map1').mouseover();
}).mouseout(function(e) {
$('#map1').mouseout();
}).click(function(e) { e.preventDefault(); });
// initialize tabbing
$(".tabs area:eq(0)").each(function(){
$(this).addClass("current");
});
$(".tab-content").each(function(){
$(this).children(":not(:first)").hide();
});
//map clicks
$(".tabs area").click(function(){
//This block is what creates highlighting by trigger the "alwaysOn",
var data = $(this).data('maphilight') || {};
data.alwaysOn = !data.alwaysOn;
$(this).data('maphilight', data).trigger('alwaysOn.maphilight');
//there is also "neverOn" in the docs, but not sure how to get it to work
if ($(this).hasClass("current") == false)
{
var thisTarget = $(this).attr("href");
$(this).parents(".tabs").find('area.current').removeClass('current');
$(this).addClass('current');
$(this).parents(".tabs").nextAll(".tab-content").children(":visible").fadeOut(1, function() {
$(thisTarget).fadeIn("fast");
});
}
return false;
});
});
You need to include the link to jquery in your html header.
1) Download jquery from jQuery.com
2) Link to downloaded file in your header
Like so:
<head>
...
<script src="/path/to/jquery-1.11.3.min.js"></script>
...
</head>
As the previous answer. But put them in the bottom of the body tag.
<html>
<head>
</head>
<body>
<script src="../path/to/jquery-1.11.3.min.js"></script>
<script src="http://davidlynch.org/js/maphilight/jquery.maphilight.min.js"></script>
</body>
</html>
you need to add the following to the header of your html code
<script type="text/javascript" src="http://davidlynch.org/js/maphilight/jquery.maphilight.min.js">
</script>
I have this script which fades in/out the page
(function($) {
$(window).load(function() {
$('#preloader').fadeOut();
$('#wrap').fadeIn();
$("a").click(function(event){
event.preventDefault();
linkLocation = this.href;
$("#wrap").fadeOut(redirectPage);
});
function redirectPage() {
window.location = linkLocation;
}
});
})(jQuery);
But I have some external links which I don't want to effect so I don't want to target these.
I have found how to test for internal links using this script
var siteURL = "http://" + top.location.host.toString();
var internalLinks = $("a[href^='"+siteURL+"'], a[href^='/'], a[href^='./'], a[href^='../'], a[href^='#']");
But I'm really stuck on how to combine the two! Any ideas please?
I think you use the regex,
Try this,
var patt = new RegExp('(\/|..\/|.\/|#|https:\/\/www.google.co.in)');
var $internalLinks = [];
$('a').each(function(index){
if(patt.test($(this).attr('href'))){
$(this).addClass('fadeclass');
};
})
$('input').click(function(){
$('.fadeclass').fadeOut('slow')
});
Demo JsFiddle
From the above code, I used the regular expression for match the href, when I mentioned external links found then I added the fadeclass. You can use fadeclass whatever.
I've created links to transition yet when the function is supposed to be called using the onmousedown event I get an uncaught undefined function. Clearly my function is defined. I'm am still learning code so what is it I don't see or understand. Any tips will be greatly appreciated.
<html>
<head>
<script type="text/javascript"src="js/jquery.js"></script>
<script type="text/javascript" src="js/jquery-ui.js"></script>
<script type="javascript">
$(document).ready(function (){
var url = "phpajaxtut.php";
});
function swapContent(cv){
$("#myDiv").html("animated gif goes here").show();
.post(url, {contentVar:cv}, function(data){
$("#myDiv").html(data).show();
});
}
</script>
Click the text
Click the text
Click the text
</head>
<body >
<div id ="myDiv">My default content</div>
</body>
</html>
Why not just use $.click(); instead, since you're already using jQuery, and forgo the hyperlinks? You can easily style some spans to look like as if that's what you want. My example just updates some text, but in there you can place / call your function.
See here:
// html
<span>Click Me</span>
<br />
<span>Click Me</span>
// js
var n = 0;
$("span").click(function(){
$(this).text($(this).text() + " " + n++);
});
Do you need a $ before .post?
$.post(url, {contentVar:cv}, function(data){
$(document).ready(function (){
var url = "phpajaxtut.php";
});
The var url isn't global. It can only be used inside the function
var url; //global url
$(document).ready(function (){
url = "phpajaxtut.php"; // set global url
});
I need to hide a div if the url of the page contains a certain word. Thanks to this site I have been able to successfully find if the url contains the word. This code works:
<script type="text/javascript">
if (window.location.href.indexOf("Bar-Ends") != -1) {
alert("your url contains bar ends");
}
</script>
but for some reason it will not work to hide a div, like this:
<script type="text/javascript">
if (window.location.href.indexOf("Bar-Ends") != -1) {
$("#notBarEnds").hide();
}
</script>
<div id="notBarEnds">this is not bar ends</div>
Anyone have any idea what is wrong with this code?
Any help is greatly appreciated
Thanks
Notice the reorder:
<div id="notBarEnds">this is not bar ends</div>
<script type="text/javascript">
if (window.location.href.indexOf("Bar-Ends") != -1) {
$("#notBarEnds").hide();
}
</script>
Or
<script type="text/javascript">
$(document).ready(function () {
if (window.location.href.indexOf("Bar-Ends") != -1) {
$("#notBarEnds").hide();
}
}
</script>
Waiting for the entire document to be "ready"
Try:
$(document).ready(function () {
if (window.location.href.indexOf("Bar-Ends") != -1) {
$("#notBarEnds").hide();
}
});
Your div hasn't necessarily loaded yet when the script runs.
You're running an inline script as the HTML is being constructed, there isn't a div named #notBarEnds at the time that the script runs, you need to run it as a function after the document has loaded.
i write it without checking it, if doesn't work change de regex :D
$(document).on('ready', function()
{
if(window.location.href.match(/Bar\-Ends/i))
$("#notBarEnds").hide();
});
I use the following code on my site. I'm wondering if I need jQuery to do it or if standard javascript can handle the process.
<script type='text/javascript'>
//<![CDATA[
$(window).load(function(){
$("a[href^='http']").click(function(event) {
event.preventDefault(); // prevent the link from opening directly
// open a pop for the link's url
var popup = window.open( this.href , "", "toolbar=no,menubar=no,location=no,scrollbars=no,resizable=no,status=no,width=340,height=10,left=250,top=175" );
// popup.blur();
// window.focus();
}); }); //]]>
</script>
It's from this page: Pop Under on Click for RSS Feed - Javascript
Yes, and it’s relatively simple: just use document.getElementsByTagName('a') and traverse the array you get, seting onclick for any elements there that have an href attribute with a value that starts with http. And make this a function that is called via the onload attribute in <html> for example.
var hrefs = document.getElementsByTagName('a');
for (i in hrefs) {
if (hrefs[i].href && hrefs[i].href.match(/^http/)) {
hrefs[i].onclick = function(){
var popup = window.open( this.href , "", "toolbar=no,menubar=no,location=no,scrollbars=no,resizable=no,status=no,width=340,height=10,left=250,top=175" );
return false;
}
}
}
you can try this
<div id="divid" onclick="showpop();">click me</div>
<script type="text/javascript">
function showpop(){
window.open(arguments);
return false;
}
</script>
document.getElementById(eleID).onClick = function (){
//do stuff
}
