There is a jQuery code that already works how I want. .foto class do the function. But I should to add .fotoleft class to do the same function. How can I do the same function for two different classes?
$(document).ready(function() {
$(".foto").click(function() {
$src = $(this).attr("src");
if (!$("#light-box").length > 0) {
$("body").append("<div id='light-box'> <span class='close'></span><img src=''></div>");
$("#light-box").slideDown();
$("#light-box img").attr("src", $src);
} else {
$("#light-box").slideDown();
$("#light-box img").attr("src", $src);
}
});
$("body").on("click", "#light-box", function() {
$("#light-box").slideUp();
});
});
You just need to use Multiple Selector (“selector1, selector2, selectorN”)
$(".foto, .fotoleft ") .click(function(){
//Your existsing code
});
If you want .fotoleft to perform the same function as .foto, I find the most efficient way of doing this would be to use .foto in your html twice, rather than in your JS twice.
I prefer this method as it makes it easier to apply a function to multiple or additional elements without needing to add more classes to the JS.
i.e.
<a class='foto'>Do Something</a>
<a class='foto fotoleft'>Do Something too></a>
You could choose to amend your css to make .foto more compatible in this way so you don't overwrite any styling.
You use groups (via a comma); these are CSS selectors, after all:
$(".foto, .fotoleft")...
You may use
$(".foto, .fotoleft") .click(function(){

Is there one function that would do the job of both of these (and anything that continued the format)?
$("#1A").hover(function(){
$(".route1A").stop().fadeToggle(500);
});
$("#1B").hover(function(){
$(".route1B").stop().fadeToggle(500);
});
The result would look something like below, where __ is code for 'these are the same':
$("#__").hover(function(){
$(".route__").stop().fadeToggle(500);
You can combine the selector for .hover() to include #1A, #1B, etc. and then just grab the id off of the element that triggered the hover event to create your class selector, like so:
$("#1A, #1B").hover(function(){
$(".route" + this.id).stop().fadeToggle(500);
});
Perhaps something like this?
var names = ["1A", "1B"]; //Extend as needed
for(var i=0; i<letters.length; ++i) {
$("#" + names[i]).hover(function() {
$(".route" + names[i]).stop().fadeToggle(500);
});
}
You can use a multi-selector. This will bind the event handler to all selectors included.
$("#1A, #1B").hover(function(){
$(".route" + this.id).stop().fadeToggle(500);
});
Note: Changed code so that images and texts are links.
Basically, I have 3 pictures all with the same class, different ID. I have a javascript code which I want to apply to all three pictures, except, the code needs to be SLIGHTLY different depending on the picture. Here is the html:
<div class=column1of4>
<img src="images/actual.jpg" id="first">
<div id="firsttext" class="spanlink"><p>lots of text</p></div>
</div>
<div class=column1of4>
<img src="images/fake.jpg" id="second">
<div id="moretext" class="spanlink"><p>more text</p></div>
</div>
<div class=column1of4>
<img src="images/real.jpg" id="eighth">
<div id="evenmoretext" class="spanlink"><p>even more text</p></div>
</div>
Here is the Javascript for the id="firsttext":
$('#firstextt').hide();
$('#first, #firsttext').hover(function(){
//in
$('#firsttext').show();
},function(){
//out
$('#firsttext').hide();
});
So when a user hovers over #first, #firsttext will appear. Then, I want it so that when a user hovers over #second, #moretext should appear, etc.
I've done programming in Python, I created a sudo code and basically it is this.
text = [#firsttext, #moretext, #evenmoretext]
picture = [#first, #second, #eighth]
for number in range.len(text) //over here, basically find out how many elements are in text
$('text[number]').hide();
$('text[number], picture[number]').hover(function(){
//in
$('text[number]').show();
},function(){
//out
$('text[number]').hide();
});
The syntax is probably way off, but that's just the sudo code. Can anyone help me make the actual Javascript code for it?
try this
$(".column1of4").hover(function(){
$(".spanlink").hide();
$(this).find(".spanlink").show();
});
Why not
$('.spanlink').hide();
$('.column1of4').hover(
function() {
// in
$(this).children('.spanlink').show();
},
function() {
// out
$(this).children('.spanlink').hide();
}
);
It doesn't even need the ids.
You can do it :
$('.column1of4').click(function(){
$(this); // the current object
$(this).children('img'); // img in the current object
});
or a loop :
$('.column1of4').each(function(){
...
});
Dont use Id as $('#id') for multiple events, use a .class or an [attribute] do this.
If you're using jQuery, this is quite easy to accomplish:
$('.column1of4 .spanlink').hide();
$('.column1of4 img').mouseenter(function(e){
e.stopPropagation();
$(this).parent().find('.spanlink').show();
});
$('.column1of4 img').mouseleave(function(e){
e.stopPropagation();
$(this).parent().find('.spanlink').hide();
});
Depending on your markup structure, you could use DOM traversing functions like .filter(), .find(), .next() to get to your selected node.
$(".column1of4").hover(function(){
$(".spanlink").hide();
$(this).find(".spanlink, img").show();
});
So, the way you would do this, given your html would look like:
$('.column1of4').on('mouseenter mouseleave', 'img, .spanlink', function(ev) {
$(ev.delegateTarget).find('.spanlink').toggle(ev.type === 'mouseenter');
}).find('.spanlink').hide();
But building on what you have:
var text = ['#firsttext', '#moretext', '#evenmoretext'];
var picture = ['#first', '#second', '#third'];
This is a traditional loop using a closure (it's better to define the function outside of the loop, but I'm going to leave it there for this):
// You could also do var length = text.length and replace the "3"
for ( var i = 0; i < 3; ++i ) {
// create a closure so that i isn't incremented when the event happens.
(function(i) {
$(text[i]).hide();
$([text[i], picture[i]].join(',')).hover(function() {
$(text[i]).show();
}, function() {
$(text[i]).hide();
});
})(i);
}
And the following is using $.each to iterate over the group.
$.each(text, function(i) {
$(text[i]).hide();
$([text[i], picture[i]].join(', ')).hover(function() {
$(text[i]).show();
}, function() {
$(text[i]).hide();
});
});
Here's a fiddle with all three versions. Just uncomment the one you want to test and give it a go.
I moved the image inside the div and used this code, a working example:
$('.column1of4').each(function(){
$('div', $(this)).each(function(){
$(this).hover(
function(){
//in
$('img', $(this)).show();
},
function(){
//out
$('img', $(this)).hide();
});
});
});
The general idea is 1) use a selector that isn't an ID so I can iterate over several elements without worrying if future elements will be added later 2) locate the div to hide/show based on location relational to $(this) (will only work if you repeat this structure in your markup) 3) move the image tag inside the div (if you don't, then the hover gets a little spazzy because the positioned is changed when the image is shown, therefore affecting whether the cursor is inside the div or not.
EDIT
Updated fiddle for additional requirements (see comments).
I have multiple elements that'll have the same data attributes but with different values, how can I get jQuery to change the value?
Below is some example HTML.
<div data-one="test" data-two="test2"></div>
<div data-one="testing" data-two="hello"></div>
<div data-one="yo" data-two="test3"></div>
By default, I would like to the value of div to be data-one but then when the class active is on the body tag, I would like it to change all the values to the data-two value.
I thought about storing values as a variable which would be easier although the divs don't have any ID's and they're scattered around in the DOM which makes it difficult.
So far I had this:
if($('body').hasClass('active')) {
$('div').html($(div).data('two'));
}
You can use html method.
var has = $('body').hasClass('active');
$('div').html(function() {
return has ? $(this).data('two') : $(this).data('one');
});
http://jsfiddle.net/44Du5/
CSS only solution:
body div:after {
content: attr(data-one);
}
body.active div:after {
content: attr(data-two);
}
http://jsfiddle.net/dfsq/gaeUR/
However it's not crossbrowser: attr function is supporter in IE8+.
Check this link: http://jsfiddle.net/rjR6q/
$(document).ready(function(){
if($('body').hasClass('active')) {
$('div').each(function(){
$(this).html($(this).data('two'));
});
}
else
{
$('div').each(function(){
$(this).html($(this).data('one'));
});
}
});
So here is my dilemma. Been trucking on this Jquery extreme code here and I need help telling if a certain link is showing or not. Here is what I have.
The toggles:
<span class="icon icon84"></span>
<span class="icon icon85"></span>
(notice the only thing that is different is the icon number) These need to toggle back and forth when someone clicks the #visbilitybutton. Not sure of the best way to do this and to capture what is selected as well.
The only code I have currently makes the toggle go one way, but doesn't go back when clicked again.
$(document).ready(function () {
$('#visbilitybutton').click(function() {
$(this).replaceWith('<span class="icon icon85"></span>');
});
});
First things first, you shouldn't have multiple identical id attributes on your page. Make visibilitybutton a class.
Anyways, you can use the jQuery toggle() function to specify what to do on each consecutive click:
$(".visibilitybutton").toggle(function(){
$(this)
.attr("title","Invisible")
.find("span").toggleClass("icon84 icon85");
}, function(){
$(this)
.attr("title","Visible")
.find("span").toggleClass("icon84 icon85");
});
If you want to be more efficient, you can do it all in one fell jQuery swoop like so, with some good techniques:
var vis = ["Invisible","Visible"];
$(".visibilitybutton").click(function(){
var i = 0;
$(this)
.attr("title",vis[i])
.find("span").toggleClass("icon84 icon85");
i = (i==0)?1:0;
});
Even more so would be to make a class that hides the element when added to it and shows it when you remove it (a classname with display:none applied in the CSS works fine):
$(".visibilitybutton").click(function(){
$(this)
.toggleClass("hide")
.find("span").toggleClass("icon84 icon85");
});
You need to have unique ids; therefore, you should select the items by class. You can use toggle() to handle the consecutive clicks, and you can use toggleClass() to handle the swapping of classes.
HTML:
<span class="icon icon84"></span>
<span class="icon icon85"></span>
Javascript:
$(document).ready(function () {
$('.button').toggle(function() {
var $button = $(this);
$button.prop("title","Invisible");
$button.find('.icon85').toggleClass('icon85', 'icon84');
}, function() {
var $button = $(this);
$button.prop("title","Visible");
$button.find('.icon85').toggleClass('icon84', 'icon85');
});
});
The id attribute is supposed to be unique to each element. Change the id attribute to the class attribute for each hyperlink.
Then, in your jQuery code, get the hyperlinks by their class name:
$('.visbilitybutton').click(function() {
// code goes here
});
In your event handler, you should use test the title attribute, like so:
$('.visibilitybutton').click(function() {
$this = $(this);
if ($this.attr("title") == "Visible")
$this.attr("title", "Invisible").find("span")
.removeClass("icon85").addClass("icon84");
else
$this.attr("title", "Visible").find("span")
.removeClass("icon84").addClass("icon85");
});
I've written the following code to add a clickable "link button" to a section of my page.
var linkButtonHtml = "<a data-makeId='" + makeId + "' href='javascript:expandMake(" + makeId + "," + categoryId + ")'>+</a> " + makeName;
var divHtml = "<div style='display:none' class='models' data-makeId='" + makeId + "'></div>" + "<br/>";
html += linkButtonHtml + divHtml;
$('#linkDiv').html(html);
The code works fine, but it's ugly and difficult to read with all the string concatenation.
As you can see, I am building anchor elements and div elements with string concatenation. The target of my anchor element is a javascript function invocation with two arguments. Is there a good jQuery way to improve the readability of this code?
I'm not sure if this really improves readability is here is a 100% jQuery solutions:
$(html)
.append(
$('<a />')
.attr('data-makeId', makeId)
.attr('href', 'javascript:void(0);')
.click(function(event)
{
// Prevent clicking the link from leaving the page.
event.preventDefault();
expandMake(makeId, categoryId);
})
.text('+'))
.append(
document.createTextNode(makeName)
)
.append(
$('<div />')
.addClass('models')
.attr('data-makeId=', makeId)
.hide());
Where "html" in $(html) is the html variable you have in your sample.
jQuery offers an option for a second argument when creating elements.
var linkButton = $('<a>',{'data-makeId':makeId,
href:'#',
click:function(){expandMake( makeId, categoryId )},
text:'+'
});
var div = $('<div>',{ style:'display:none',
'class':'models',
'data-makeId': makeId
})
.after('<br>');
$('#linkDiv')
.empty()
.append(html)
.append(linkButton)
.append( makeName )
.append(div);
EDIT: Fixed an issue where makeName was not appended.
Only real way is either abstracting some of your tag generation or spread the script out a little to make it more readable : http://jsfiddle.net/3dYPX/1/
Your also using jQuery so you might want to consider changing the way you trigger the javascript. Try looking into the .live() event. (Ill just get an example up, not that its very important)
Using live event for unobtrusive javascript:
http://jsfiddle.net/3dYPX/2/
It is all being done inside of the onLoad event at the moment, just to use as an example.
Use a template library such as
jQuery Templates instead of inlining
HTML.
Instead of using "javascript:" URLs, attach event handlers to the generated DOM fragments.
Refrain from using inline styles.
Something like:
$('#linkDiv')
.empty()
.append($.tmpl(myTemplate, {
makeId: makeId,
makeName: makeName,
categoryId: categoryId
}))
.click(function () {
var makeId = $(this).attr("data-makeId");
if (makeId) {
expandMake(makeId, $(this).attr("data-categoryId"));
}
});
Where myTemplate has the content:
${makeName}
<div class="models" data-makeId="${makeId}"></div>
Instead of using an inline style to initially hide the models, hide them all with a general CSS rule, and then selectively show them with a class:
.models { display: none }
.models.shown { display: block }
Just add the "shown" class to show a certain block of models.
Here you go:
$('#linkDiv').empty().append([
$('+').data('makeId', makeId).click(function(e) {
e.preventDefault();
expandMake(makeId, categoryId);
})[0],
$('<span>').text(makeName)[0],
$('<div class="models">').data('makeId', makeId).hide()[0],
$('<br>')[0]
]);
Live demo: http://jsfiddle.net/cncbm/1/
Consider this:
$('#linkDiv').data({'makeId': makeId, 'categoryId': categoryId}).empty().append([
$('+').click(expandMake)[0],
$('<span>').text(makeName)[0],
$('<div class="models">').hide()[0]
]);
So, you define that data-stuff on the parent DIV (the common parent) and you re-factor the expandMake function so that it reads those data-values from the parent DIV instead of passing them as arguments.
