I'm looking for a more elegant way to make a hide/show of divs using inline Javascript.
If you mouse over the orangish/yellow circle logos over the cars the tag should appear. When moused out they should disappear.

<div class="second">
<div id="speech2" style="display: none">
<img src="<?php bloginfo('template_url'); ?>/images/speech2.png" width="334" height="50">
</div>
<a id="various2" href="#inline2,javascript:HideContent('speech1')" title="" onmouseover="HideContent('speech1'); return true;">
<img src="<?php bloginfo('template_url'); ?>/images/clicker.png" width="62" height="50" onmouseover="document.getElementById('speech2').style.display = 'block'" onmouseout="document.getElementById('speech2').style.display = 'none'">
</a>
</div>
Here's the pastebin of the code used:

The more elegant solution is to utilize JQuery.
Once you include the library into a file, a div show is done using the following selector
$('#idOfDiv').show();
Or if there are no ids but rather classes
$('.ClassName').show();
Now instead of having onclick events in the html as you have right now, you just bind them in jquery in the ready() method like so:
$(document).ready(function()
{
$('#idOfDiv').bind('click', function()
{
//do work here in this anonymous callback function
});
});
All of this can be done in a external js file so that will significantly clean up your html code
and put all your javascript logic into one location.
EDIT:
Example applied to your situation
$(document).ready(function()
{
$('#various1').mouseover(function()
{
$('#speech1').show();
});
$('#various1').mouseout(function()
{
$('#speech1').hide();
});
});
If you get crafty and utilize a for loop then you could just append the number to the end of the string that represents the selectors like so
$(document).ready(function()
{
for(var i = 1; i < 7; i++)
{
$('#various' + i).mouseover(function()
{
$('#speech' + i).show();
});
$('#various' + i).mouseout(function()
{
$('#speech' + i).hide();
});
}
});
The mouseout and mouseover functions are just the explicit version of using like so
$('selector').bind('mouseover', function()
{
});
$('selector').bind('mouseout', function()
{
});
Have you looked into using jQuery for this? Also, why does the code need to be inlined?
I would recommend doing something like this: http://jsfiddle.net/4N9ym/2/
Note that I have things inverted here (you would probably want to animate in instead of animating out).

Im fairly new to javascript and I just can't figure this out despite my attempt in researching. How do I track the change of a input within a div and trigger an append to an outside div? My code goes as follow:
Append h3 with "Pending" once ".image-value" input has a change in value
<!-- APPEND <h3> -->
<h3>Best Overall Costume<div class="pending">Pending</div></h3>
<div>
<div class="select-form">
<img src="images/vote.jpg" data-value="image_value">
<img src="images/vote.jpg" data-value="image_value2">
<img src="images/vote.jpg" data-value="image_value3">
<img src="images/vote.jpg" data-value="image_value4">
<img src="images/vote.jpg" data-value="image_value5">
<!-- Track the change of this input -->
<input type="hidden" class="image-value" name="selected_image" value="">
</div>
</div>
I tried this:
function changeStatus(statusValue) {
$("input",".select-form").val(statusValue).trigger("change");
}
$("input",".select-form").change(function(){
if (!$(this).val()){
$("<div class='pending'>Pending</div>").appendTo($("h3").prev($(this)));
}
});
But that didn't seem to work. Any ideas?
place an empty div where you want your new div and give it an id i.e(<div id='myDiv'><div>) and then append what you want like this.
$( "#myDiv" ).append( "<div class='pending'>Pending</div>" );
You can also check Append Explained
for more explanations.
Thanks.
I've done a couple things here... First, I'm not sure why you had it all in a named function. When you're using event listeners that often isn't necessary.
Then, I don't know what the val check was for, so I reversed it.
Finally, I'm using one(), which only runs once. This case seemed to call for that.
$('.select-form').one('change', 'input', function () {
if ( $(this).val() ) { alert('asdgf');
$("<div class='pending'>Pending</div>")
.appendTo($(this).parent().prev('h3'));
}
});
Fiddle
try this:
$("input",".select-form").on("change", function(){
var $this = $(this);
if (!$this.val()){
var elem = $('<h3>Best Overall Costume<div class="pending">Pending</div></h3>');
$this.parent().parent().before(elem);
}
});
you can also place a check, that if the pending div is already added, not to add it again.
Of course this solution assumes that there are no other nested divs between the target div(before which you want to append) and the input control
The below code is working in firefox and chrome but not in safari. Can anybody tell me if this is the correct way to add multiple classes and id's in jquery?
jquery
$(document).ready(function () {
$('.imgLink, .imgLink1, .imgLink2, .imgLink3, .imgLink4, .imgLink5, .imgLink6,
.imgLink7, .imgLink8, .imgLink9').click(function () {
var imgPath = $(this).attr('href');
$('#theImage, #theImage1, #theImage2, #theImage3, #theImage4, #theImage5, #theImage6,
#theImage7, #theImage8, #theImage9').attr('src', imgPath);
return false;
});
});
html for .imgLink
<a class="imgLink1" href="http://www.customtie.com/images/press/printwear-11-2013.jpg">Printwear Nov 2013</a>
hmtl for #theImage
<img id="theImage" src="http://www.customtie.com/images/press/counselor-2-2014.jpg" alt="" width="auto" height="auto">
Ugh... Classes are not meant to be used that way. Rather:
FOO
BAR
<img id="theImage1" src="images/default.jpg" alt="">
<img id="theImage2" src="images/default.jpg" alt="">
$(function () { // DOM ready shorthand
$('.imgLink').click(function ( e ) {
e.preventDefault();
var imgPath = $(this).attr('href');
var targetID = $(this).data('targetid');
$('#theImage'+ targetID).attr('src', imgPath);
});
});

So basically you add the same class to all your clickables, and a data-* attribute with the number of the image ID suffix you want to target.
There's also other nice ways (even simpler) to achieve the same, but without seeing some HTML it's blind guessing.
I would first agree with m90's suggestion that you want to just add a single class to all these elements and select off that.
But I would presume that the issue is the carriage return halfway through your string. If you want to start a new line, you have to end the first one and then concatenate them together like this:
$('.imgLink, .imgLink1, .imgLink2, .imgLink3, .imgLink4, .imgLink5, .imgLink6,'+
'.imgLink7, .imgLink8, .imgLink9').click(function () {
var imgPath = $(this).attr('href');
$('#theImage, #theImage1, #theImage2, #theImage3, #theImage4, #theImage5, #theImage6, ' +
'#theImage7, #theImage8, #theImage9').attr('src', imgPath);
return false;
});
Here is my code:
HTML
<img src"../MyPic_1" id="MyImg_1" onclick = "MyJQfunction($(this))">
<img src"../MyPic_2" id="MyImg_2" onclick = "MyJQfunction($(this))">
<img src"../MyPic_3" id="MyImg_3" onclick = "MyJQfunction($(this))">
JQUERY
<script>
function MyJQfunction(MyField)
{
MyField.hide();
}
</script>
As you can see I'm trying to send the HTML element to my JQ Function so it knows what to hide.
What am I doing wrong?
NOTE: This is just a simple example of what I really need to do, I just want to avoid including codes that you don't care about. Thanks!
You are using jquery so attach an event handler instead of using onclick
<img src="../MyPic_1" id="MyImg_1" class="myIMage">
<img src="../MyPic_2" id="MyImg_2" class="myIMage">
<img src="../MyPic_3" id="MyImg_3" class="myIMage">
and
$(function(){
$('.myIMage').on('click', MyJQFunction);
}
function MyJQFunction()
{
$(this).hide(); //here this represents the element clicked.
}
Or classic way; use Function.call to set the context for the function while invocation.
<img src"../MyPic_1" id="MyImg_1" onclick = "MyJQfunction.call(this)">
and
function MyJQFunction()
{
$(this).hide(); //and this here is now the clicked element.
}
Also in your code your image tag seems to be incorrect and MyJQfunction versus MyJQFunction has casing (note the casing of f) issue. Check your console for errors. Otherwise your code should work.
This is what I would do:
<img src="../MyPic_1" id="MyImg_1" class="image_to_hide"/>
<img src="../MyPic_2" id="MyImg_2" class="image_to_hide"/>
<img src="../MyPic_3" id="MyImg_3" class="image_to_hide"/>
...
<script>
$(".image_to_hide").click(function(){
$(this).hide();
});
</script>
You should wrap that on jquery function like this
function MyJQFunction(MyField)
{
$(MyField).hide();
}
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).
Is there something wrong with this code? I am trying to do the simple action of changing the src of an img named "midimg" upon mouse-click. It's not working and i don't know why
<script type="javascript">
function buttonInCompany()
{
$('#desc').load('incompany.html');
document.images["midimg"].src="http://cageme.herokuapp.com/css/mrcage.jpg";
}
</script>
<div onClick="buttonInCompany()">Everything is cage's cage.<br><br></div>
<img name="midimg" src="http://3.bp.blogspot.com/-BdfyYy_Y0gY/UP_3y3F2RDI/AAAAAAAAC-Q/eHPCltO8bG8/s1600/TomEngelsnicolas+thing.jpg">
Do you need the jQuery line? I just dropped it, than it works as expected.
function buttonInCompany()
{
document.images["midimg"].src="http://cageme.herokuapp.com/css/mrcage.jpg";
}
Seeing as how you are apparently already using a js framework (I assume jQuery), why not do it a more proper way to begin with?
<script type="text/javascript">
function buttonInCompany()
{
$('#desc').load('incompany.html');
$('#midimg').attr("src","http://cageme.herokuapp.com/css/mrcage.jpg");
}
$(document).ready(function() {
$("#someID").click(function() {
buttonInCompany();
});
});
</script>
<div id='someID'>Everything is cage's cage.<br><br></div>
<img id="midimg" src="http://3.bp.blogspot.com/-BdfyYy_Y0gY/UP_3y3F2RDI/AAAAAAAAC-Q/eHPCltO8bG8/s1600/TomEngelsnicolas+thing.jpg">
