I have some javascript code and a button which already has an event/action assigned to it, and I want to add a second event to the button. Currently the relevant bit of code looks like this:
events: {onclick: "showTab('"+n+"')"},
how do I amend this code so that it also increases the 'wdith' property of a div with class='panel', by a fixed amount eg 50px?
Thanks
EDIT:
I understand. Problem is I don't know how to change id, only classname. The div is constructed in javascript using buildDomModel as follws:
this.buildDomModel(this.elements["page_panels"],
{ tag: "div", className: "tab_panel",
id: "tab_panel",
childs: [...]}
)
But the id doesn't get changed to 'tab_panel'. HOWEVER, classname does get changed to 'tab_panel' which is why i tried to use getelementbyclass. So the div has no id and I don't know how to create one using the buildDomModel but I can give unique class. I have put the code in original post too.
This:
events: {onclick: "showTab('"+n+"'); $('div.panel').width('50px');"},
Or you might want to add below line to
showTab
function.
$('div.panel').width('50px');
Update:
Or you can do with vanilla javascript:
function setWidth()
{
var div = document.getElementById('div_id');
div.setAttribute('width', '50px');
}
Or if you want to apply the width to just one specific div, give that div an id and use this function instead:
events: {onclick: "showTab('"+n+"'); setWidth();"},
And later use it like this:
setWidth();
Or you might want to add below line to showTab
function.
setWidth();
Update 2:
Ok modify the function like this:
function setWidth(){
jQuery('.tab_panel').each(function(){
jQuery(this).attr('style', 'width:' + (jQuery(this).width() + 50));
});
}
Note that with jQuery it should be this code in all:
function setWidth(){ jQuery('.tab_panel').each(function(){ jQuery(this).attr('style', 'width:' + (jQuery(this).width() + 50)); }); }
instead of the function you can use this line of JQuery code:
$('div.tab_panel').attr('style',"width:100px");
any way if you dont want it to be JQuery then this function should work :
function setWidth() {
var divs = document.getElementsByTagName('div');
for (var i = 0; i < divs.length; i++) {
// check if this div has panel class
if (divs[i].getAttribute('class') === 'tab_panel') {
// set the style now
divs[i].setAttribute('style', 'width:100px');
}
}
}
putting width attribute to div wouldnt work, you need to set its style,
so i expect any of the code i provided to work.
oh no the one i sent early just set width to a new value this one should fix your problem :
var x = $('div.tab_panel')[0].style.width.replace("px", "");
x = x + 50;
$('div.tab_panel').attr('style', "width:" + x + "px");
ok here is a non JQuery Version :
function setWidth() {
var divs = document.getElementsByTagName('div');
for (var i = 0; i < divs.length; i++) {
if (divs[i].getAttribute('class') === 'tab_panel') {
var x = divs[i].style.width.replace("px", "");
x = x + 50;
divs[i].setAttribute('style', 'width:' + x + 'px');
}
}
ok here it is :
JQuery:
function Button1_onclick() {
var x = $('div.tab_panel')[0].clientWidth;
x = x + 50;
$('div.tab_panel').attr('style', "width:" + x + "px");
}
non JQuert:
function setWidth() {
var divs = document.getElementsByTagName('div');
for (var i = 0; i < divs.length; i++) {
if (divs[i].getAttribute('class') === 'tab_panel') {
var x = divs[i].offsetWidth;
x = x + 50;
divs[i].setAttribute('style', 'width:' + x + 'px');
}
}
}
this should work
