i want to make the map'e height is auto with the device's screen...
but when i change the style.height to auto, 100%, screen.height, the map is disappear...
how to make the height is auto?
this is my code...
script.js
$('#home').live('pagecreate',function(){
document.getElementById('map_canvas').style.width=screen.width;
document.getElementById('map_canvas').style.height="20em";
});
in index.html i just called
<div id="home" data-role="page">
<div data-role="header">
*my header*
</div>
<div data-role="content">
<div id="map_canvas"></div>
</div>
</div>
if you use jquery you can do as below:
instead of this:
document.getElementById('map_canvas').style.width=screen.width;
document.getElementById('map_canvas').style.height="20em";
you can use:
$("#map_canvas").css({
'width':screen.width,
'height':"20em"
});
Please check this example:
I think your problem is related to css not to javascript.
The % height you want to set will be based on the parent height, so if the parent is empty, the 100% of 0 will be 0: check this
code example:
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<body>
<style>
#map_canvas{
background-color:#00F;
}
#cont{
background:#F00;
height:200px;
}
</style>
<button onClick="doit1()">Click me to put something in map_canvas</button>
<button onClick="doit()">Click me to make the height 100%</button>
<div id="home" data-role="page">
<div data-role="header">
*my header*
</div>
<div id="cont" data-role="content">
<div id="map_canvas"></div>
</div>
</div>
</body>
<script>
$('#home').live('pagecreate',function(){
$('#map_canvas').css('height','auto');
});
function doit(){
$('#map_canvas').css('height','100%');
}
function doit1(){
$('#map_canvas').html('a')
}
</script>

I am working on a site.I need horizontal scrolling on a particular section,for that i am using JinvertScroll jquery.When i run that jquery's example the scrolling is working on entire page.how can i set the scrolling for particular section only??I mean how can i set that particular div that should scroll?Here is the code.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="css/example.css" />
</head>
<body>
<section id="scrolll">
<div class="middle scroll" style="border:solid red;backgroun:red">
<img src="images/middle.png" alt="" />
</div>
<script type="text/javascript" src="../libs/jquery.min.js"></script>
<script type="text/javascript" src="../src/jquery.jInvertScroll.js"></script>
<script type="text/javascript">
(function($) {
var scrolll= document.getElementById('scrolll');
var elem = $.jInvertScroll(['.scroll'], // an array containing the selector(s) for the elements you want to animate
{
height: 600, // optional: define the height the user can scroll, otherwise the overall length will be taken as scrollable height
onScroll: function(percent) { //optional: callback function that will be called when the user scrolls down, useful for animating other things on the page
console.log(percent-50);
}
});
$(window).resize(function() {
if ($(window).width() <= 768) {
elem.destroy();
}
else {
elem.reinitialize();
}
});
}(jQuery));
</script>
</section>
<section>
<div style="border:solid orange;height:1000px"></div>
</section>
</body>
</html>
<div id="scrollDiv" style="overflow:auto;">
// write code here over which scroll will be applied
</div>
The section you want to scroll place it inside a div . Give that div an Id e.g. scrollDiv and Place a style attribute on it as shown in the example above.
You don't need plugin for that. Just use height and overflow-y where you want a scroll
#scrolll{height: 600px;
overflow-y: scroll;}
<section id="scrolll">
<div class="middle scroll" style="border:solid red;backgroun:red">
<img src="images/middle.png" alt="" />
</div>
</section>
<section>
<div style="border:solid orange;height:1000px"></div>
</section>
I am struggling to change CSS based on user actions with some script. Currently I have each navBar button performing 5 functions onClick. 1 each to change the CSS of 5 different divs. Since I am newer to scripting, I wanted to make an example similar to what I am doing in order to refer back in the future as well as hopefully help out the next person to come along.
Can someone please help me with this short example? I have tried many various scripts and just end up destroying my spirits.
For this, I want to click an openButton in the navBar and have it change the width (essentially open) a corresponding div on the page.
<div id="navBar">
<a id="div1OpenButton" class="openButton" onClick="openDiv()">div1</a>
<a id="div2OpenButton" class="openButton" onClick="openDiv()">div2</a>
<a id="div3OpenButton" class="openButton" onClick="openDiv()">div3</a>
</div>
<div id="main">
<div id="div1"></div>
<div id="div2"></div>
<div id="div3"></div>
</div>
<style>
#div1 {width: 0px;}
#div2 {width: 0px;}
#div3 {width: 0px;}
</style>
Don's use onclick within your HTML - that is bad practice. You want a separation of concerns, with your JS in a separate file.
If you use jQuery (which a good library for a use-case like this), you can use its powerful selector to select all five elements at the same time. jQuery's selector is nice for beginners because it's identical to how you use selectors in CSS.
I also like to attach my JS to my HTML via IDs, not classes. This way, you know your JS has unique HTML targets to attach to.
Putting all of this together, use the jQuery selector to select all buttons, then use a .click() event to encapsulate your CSS manipulation in an anonymous function:
$(".openButton").click(function() {
$("#div1, #div2, #div3").css("width", "500px");
});
There are better ways to do it, but following the line of your code, you must pass a param to your openDiv function such as the ID of the element you want to show.
<a id="div1OpenButton" class="openButton" onClick="openDiv('div1')">div1</a>
Your onClick function must to hide all divs inside your "main" and show only the id you just passed by param.
If you need more help, paste your code please.
Try this
<html><head>
<script src=path/to/jquery.js></script>
</head><body>
<div id="navBar">
<!-- openDiv(1) with "1" is the div number -->
<a id="div1OpenButton" class="openButton" onClick="openDiv(1)">div1</a>
<a id="div2OpenButton" class="openButton" onClick="openDiv(2)">div2</a>
<a id="div3OpenButton" class="openButton" onClick="openDiv(3)">div3</a>
</div>
<div id="main">
<div id="div1">div1 opened</div>
<div id="div2">div2 opened</div>
<div id="div3">div3 opened</div>
</div>
<style>
div#main div {overflow:hidden;width:0px} //to hide div content while closed
</style>
<script>
function openDiv(n) {
$('#div'+n).width(400);} // set width to 400px
</script>
</body></html>
OR without the inline onClick()
<html><head>
<script src=path/to/jquery.js></script>
</head><body>
<div id="navBar">
<a id="div1" class="openButton" >div1</a>
<a id="div2" class="openButton" >div2</a>
<a id="div3" class="openButton" >div3</a>
</div>
<div id="main">
<div id="div1">div1 opened</div>
<div id="div2">div2 opened</div>
<div id="div3">div3 opened</div>
</div>
<style>
div#main div {overflow:hidden;width:0px} //to hide div content while closed
</style>
<script>
$('a.openButton').click(function() {
var itm = $(this).attr("id");
$("#main div#"+itm).width(400);} );// set width to 400px
</script>
</body></html>
Firstly, don't mix HTML, CSS and JavaScript in the same file. You should write your JavaScript code in a .js file, and your styles in an external stylesheet ;
Add handlers on events in your JavaScript code by using element.addEventListener() ;
Use data attributes on your buttons to link them with target divs.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1">
<title>My page</title>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
<div id="navBar">
<a class="openButton" data-target="div1">div1</a>
<a class="openButton" data-target="div2">div2</a>
<a class="openButton" data-target="div3">div3</a>
</div>
<div id="main">
<div id="div1" class="container hide"></div>
<div id="div2" class="container hide"></div>
<div id="div3" class="container hide"></div>
</div>
</body>
</html>
And in the script.js file:
document.addEventListener('DOMContentLoaded', function(event) {
var divs = document.querySelectorAll('.openButton');
for (var i = 0; i < divs.length; i++) {
divs[i].addEventListener('click', openDiv);
}
});
function openDiv(e) {
// Use e.target.dataset.target
// Add 'hide' class on all containers
var containers = document.querySelectorAll('.container');
for (var i = 0; i < containers.length; i++) {
containers[i].classList.add('hide');
}
// Remove 'hide' class on the container to display
document.getElementById(e.target.dataset.target).classList.remove('hide');
}
<a id="div1OpenButton" class="openButton" onClick="openDiv(this)">div1</a>
<script>
function openDiv(e){
document.getElementById(e.innerHTML).style.width= '20px'
}
</script>
Let's say my html is setup like this:
<html>
<head>
</head>
<body>
<div id="site_banner">
<img>
</div>
<div id="site_content">
<div id="home_menu"></div>
<div id="home_content"></div>
</div>
</body>
</html>
All I want is my home_content to fill the rest of the view and then any additional content in home_content to be in overflow instead of overflow being in html, so that the site_banner and home_menu are always on screen as the user scrolls down and never disappears.
From what you're saying it sounds like you should be putting the "site banner" and "home menu" in a header tag which means it should be structured like this.
<html>
<head>
</head>
<body>
<header>
<div id="site_banner"><img></div>
<div id="home_menu"></div>
</header>
<div id="site_content">
<div id="home_content"></div>
</div>
</body>
here's a fiddle of it https://jsfiddle.net/Optiq/rx2qn1h9/
Here's the CSS I added to make it stay put
header{
position:fixed; /*this makes it stay in place*/
display:block;
top:0px; /*this bumps it to the very top of the page*/
width:100%;
height:80px;
background-color:red;
}
Using jQuery:
$("#site_content").height($(window).height()-$("#site_banner").height());
$("#home_content").css("overflow-y","auto").height($("#site_content").height()-$("#home_menu").height());
Here's a JSfiddle:

I have assigned the 80% height of the viewport to my div as height. In Button click I have displayed the height of the div. This works fine in ie9, ie10. But in ie7, ie8 $("#divContainer").height() is 0. Am I doing anything wrong and how to get the height of the div in IE7, IE8(vml)
<html style="height:100%;">
<body style="height:100%;">
<div id="divContainer" style="height:100%; border:2px solid #ff0000">
</div>
<button id="button1"></button>
<script type="text/javascript">
$(function () {
$("#button1").click(function()
{
alert($("#divContainer").height());
});
});
</script>
</body>
</html>
Thanks In Advance
For IE you may try pure javascript solution
var height = getElementById("divContainer").clientHeight;
Most importantly include jQuery Library in your Code's head section and use .css("height") instead of .height()
Modified code is as below
<html style="height:100%;">
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
</head>
<body style="height:100%;">
<button id="button1" value="text"></button>
<div id="divContainer" style="height:100%; border:2px solid #ff0000">
</div>
<script type="text/javascript">
$(function () {
$("#button1").click(function()
{
alert($("#divContainer").css("height"));
});
});
</script>
</body>
</html>
Note I have taken Button above the container.
you can use jquery - Height option
or
use jquery with css option of any properties of tag or id.
like
<div id="divContainer" style="height:100%; border:2px solid #ff0000">
</div>
<script type="text/javascript">
$(function () {
$("#button1").click(function()
{
alert($("#divContainer").css("height"));
//also set the height too as
$("#divContainer").css("height", "80%");
});
});
i have 4 images and then i have applied automatic swiping,It's working nice,but now i have added text (skip) on Image when i click on Skip,text is Redirected to another page(text.html)
My Problem is When i Click Skip it's Redirected page(text.html) but page css not applied.
But with out click on skip with automatic sliding redirected page(text.html) is fine.
<div id="container">
<img src="../images/4 copy.jpg" alt=""/><br/>
<div class="caption"><font color="white" >fourth Second dfasdfasasdasdasdna asdasdasdasd asdasdasd asdasd<br/> asdasdasd asdadasd asdasdad</font> <font color="white"><span class="one">skip</span></font>
</div>
</div>
when click skip it's redirect to text.html but text.html css not applied total page will changed
when call direct text.html it's displayed nice css also applied
can you please tell me how to make css apply to text.html when i click skip.
Thanks in Advanced

This is a common jQuery Mobile misconception.
You need to learn how jQuery Mobile handles pages. Only initial HTML file is fully loaded into the DOM. Every other HTML page is only partially loaded, basically lets say we have 2 HTML files, one is called index.html and second one is called second.html.
When jQuery Mobile app is initialized, framework will load index.html into the DOM.
When you go to other page, in our case second.html, only data-role="page" container div is going to be loaded into the DOM, everything else is discarded.
This is because jQuery Mobile used AJAX for page handling. If first file is already inside the DOM, there's no reason in loading HEAD content of other HTML files.
Read more about it here.
In your case just move your <style></style> to a data-role="page" container div.
Basically do this:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1"/>
<link rel="stylesheet" href="../css/jquery.mobile-1.4.2.min.css"/>

var footer = $(".ui-footer").hasClass("ui-footer-fixed") ? $(".ui-footer").outerHeight() - 1 : $(".ui-footer").outerHeight();
var contentCurrent = $(".ui-content").outerHeight() - $(".ui-content").height();
var content = screen - header - footer - contentCurrent;
$(".ui-content").height(content);

for js try
document.location = url
with jQuery you can define class on which you can perform an on-click event
like
$( ".skipclass" ).on( "click", function() {
// do something here like
// window.location.href='the_link_to_go_to.html';
// or ajax request
});
