Changing href attribute to generated string from API with jquery - javascript

I want to change the href attritube of link on this part of the code
I'm using this code to change the href attribute
$('a').attr('href', function() {
return this.href + update.response;
});
I tried to make a variable in this function
function update(response) {
$('#response').html(JSON.stringify(response.quoteText));
var okay = $('.author').html(JSON.stringify(response.quoteAuthor));
}
But I can't seem to access it from outside scope.
Basically I want to link to Wikipedia author page by adding the $('.author') name at the end of link.
Added the update.response to the end of link but I get undefined

Just update the href at the point you get your response.
eg.
http://codepen.io/anon/pen/rrJYbJ
var a = $('a'),
wiki = a.attr('href');
function update(response) {
$('#response').html(JSON.stringify(response.quoteText));
$('.author').html(JSON.stringify(response.quoteAuthor));
a.attr('href',wiki + response.quoteAuthor);
}

Where is response coming from?
did you declare it as a global variable? eg var response;
if so then just place this code:
$('a').attr('href', function() {
return this.href + response; // you dont need update.response just response
});
after wherever you're calling update();

There's some erros in your code:
Where response came from?
You should update link href after receive data from api.
You can try to alter your code like this:
And js:
function update(response) {
$('#response').html(JSON.stringify(response.quoteText));
$('.author').html(JSON.stringify(response.quoteAuthor));
$('a').each( function () {
var newHref = $(this).data('data-base-href')+response.quoteAuthor;
$(this).attr('href',newHref );
});
}

Grab URL parameter onclick of url.. Jquery, Javascript

I am having some trouble trying to store the url parameters of some dynamic links that I created with an ajax post response. The ajax post is working correctly and the name and subgenre vars are being properly filled from the ajax response. Now what I would like to happen is that a user clicks on one of the generated urls, the parameters inside of the urls, i.e. subgenre="blah", are going to be sent to a database and stored. The problem I am having is that a standard event click function will not work inside or outside of the document ready function.
$(document).ready(function() {
$.each(data, function() {
$('#artist-suggestions').append('<li>' + this.name + this.new + '</li>');
});
});
I then created an onclick function, as below, but I can not use the "this" query because it is outside of the document scope. I had to put the onclick function outside of the document ready function or else it would not work.
function artistGen(){
alert('dfdsf');
};
What am I missing here or what am I doing wrong?
You can pass these in the onclick function when you make each element.
$(document).ready(function() {
$.each(data, function() {
artist = this.name;
$('#artist-suggestions').append('<li>' + this.name + this.new + '</li>');
});
})
;
function artistGen(Blah1, Blah2){
saveData(Blah1, Blah2);
alert('dfdsf');
};
In jQuery for dynamic elements you can use the click event in this way
$('#artist-suggestions li').on('click', 'a', function() {
// do something
});
or you can continue with the way you did, by using a function but just add a parameter to that function
like
function artistGen(Artist){
// do something
};
You need to remove the artistGen() function from the scope of the .load()
$(window).load(function(){
$('#artist-suggestions').append('<li>jim new</li>');
});
function artistGen(){
alert('dfdsf');
}
JSFIDDLE DEMO
That's just how it is a function called in those event attributes have to be defined globally(or defined right there) not in any wrapper function. A better solution would be to attach event handlers.
$(document).ready(function() {
function artistGen(){
alert(this.href);
};
$.each(data, function() {
var $li = $('<li>' + this.name + this.new + '</li>');
$li.find('a').on('click', artistGen);
$('#artist-suggestions').append($li)
});
});

jquery.get function url parameter

in the jquery.get() function, the first parameter is URL, is that the url to the content I want to retrieve or to the Controller/action method.
The problem is I'm building an asp.net-mvc application and I'm not sure what to pass as this parameter. Right now I'm passing my partialview.cshtml but nothing is being returned, not sure if I'm doing this right or wrong.
Here's what I got
<div id="editor_box"></div>
<button id="add_button">add</button>
<script>
var inputHtml = null;
var appendInput = function () {
$("#add_button").click(function() {
if (!inputHtml) {
$.get('AddItem.cshtml', function (data) {
inputHtml = data;
$('#editor_box').append(inputHtml);
});
} else {
$('#editor_box').append(inputHtml);
}
})
};
</script>
also, what is the second parameter "function (data)" is this the action method?
You need to remove var appendInput = function () { from the script. You are defining a function but never calling it. Just use the following (update you action and controller) names
<script>
var inputHtml = null;
$("#add_button").click(function() {
if (!inputHtml) {
$.get('#Url.Action("SomeAction", "SomeController")'', function (data) {
inputHtml = data;
$('#editor_box').append(inputHtml);
});
} else {
$('#editor_box').append(inputHtml);
}
});
</script>
Edit
Based on your script you appear to be requiring the content only once (you then cache it and add it again on subsequent clicks. Another alternative would be to render the contents initially inside a hidden <div> element, then in the script clone the contents of the <div> and append it to the DOM
<div id="add style="display:none">#Html.Partial("AddItem")</div>
$("#add_button").click(function() {
$('#editor_box').append($('add').clone());
});
The first argument to $.get is the URL which will respond with the expected data. jQuery/JavaScript don't care what kind of server side architecture you have or the scripting language. Whether the URL looks like a file AddItem.cshtml or a friendly route like /User/Sandeep, it doesn't matter as far as the client side is concerned.
In the case of ASP.NET, your URL endpoint can be generated like so:
$.get('#Url.Action("SomeAction", "SomeController")', function (data) {

Recover href attribute in javascript function?

I have a problem getting the href attribute of a link. In have the following code in my DOM
$("a").click(function(e) {
e.preventDefault();
myFunction(this);
});
In my linked js file I want to manipule the href attribute, let's say :
function myFunction() {
var hrefValue = $(this).attr("href");
alert(hrefValue );
}
But Is displays 'undefined'.
What am I doing wrong ?
Thanks a lot for your help !
You never accept a parameter in your function!
function myFunction(el) {
var hrefValue = $(el).attr("href");
alert(hrefValue);
}
Try using .call to maintain the context,
myFunction.call(this)

How do you get a return value from a colorbox?

I have a colorbox that lets the user select an image. How do I get the file name back from the colorbox? (I have noticed the onClosed function.)
Solution:
As #Gummy sugested i used the onComplete function as the following code exemplifies:
'Return' page:
<input id="colorbox_hidden_return" type="hidden"/>
...
$("#whatever-you-want-to-click-on-to-get-the-color-box").click(function() {
$.colorbox(
{
href: '<?= site_url('the-source-url') . '/' ?>' + id,
height: "600px;",
onClosed: function() { // called when the colorbox closes
var image = $('#colorbox_return_hidden').val();
// ... other processing - what ever the value was is in image
}
});
});
In the colorbox source
var image_name_var = "dynamicaly_change_this_name.png";
$('#submit-or-use-button-id').click(function() {
$('#colorbox_return_hidden').val(image_name_var);
});
Any time while colorbox is open, you can call the element method to retrieve a jQuery object of the current element. From there you can select the element, and access the href property:
href = $.colorbox.element()[0].href;
Also, in any callback the execution context (the value of 'this') will be the current element. So if you wanted to use the onComplete callback for example, you could do something like this:
$('#example').colorbox({onComplete:function(){
href = this.href;
}});
This might do it for you
$(document).bind("cbox_complete", function(){
var href = $.colorbox.element().attr("href");
//do something else
});

b.createDocumentFragment is not a function (jQuery)

I'm playing around with a function and getting
b.createDocumentFragment is not a function (jQuery)
My function is
function tweetCount(url) {
$.getJSON("http://urls.api.twitter.com/1/urls/count.json?url="+url+"&callback=?", function(data) {
count = data.count
$(this).append(count);
})
}
I've tried lots of different way but can't seem to find out why it doesn't like "append". "count" is a number and something like alert(count) works, but not append!
Any help?!
Alex
I don't think that this is referring to what you think it is. Change $(this) to an explicit reference to the DOM element you want.
Alternatively, you can define this by calling:
tweetCount.call($("#element"), url)
Edit
Try this:
$("span.tweetcount").each(function(){
url = $(this).attr('title');
tweetCount.call(this, url);
});
Or, to save space:
$("span.tweetcount").each(function(){
tweetCount.call(this, $(this).attr('title'));
});
Edit 2:
Try replacing tweetCount with this:
function tweetCount(url) {
var that = this;
$.getJSON("http://urls.api.twitter.com/1/urls/count.json?url="+url+"&callback=?", function(data) {
count = data.count;
$(that).append(count);
})
