I've the following snip of a code:
var about = "about.html";
function loadPage(target){
$("#dashboard").load(target);
}
$(".nav li").click(function(){
loadPage($(this).attr("class"));
});
So when I click on a button like <li class="about">, target is = about.
But in that way, $("#dashboard").load(target); doesn't load the variable about which is the html-file which I want to load.
So how is it possible to call the variable in this way?
You seem to miss the .html part. Try with
$("#dashboard").load(target+'.html');
But, supposing you have only one class on your li element, you'd better use this.className rather than $(this).attr("class").
EDIT :
if you want to use your about variable, you may do this :
$("#dashboard").load(window[target]);
But it would thus be cleaner to have a map :
var pages = {
'about': 'about.html',
'home': 'welcome.jsp'
}
function loadPage(target){
$("#dashboard").load(pages[target]);
}
$(".nav li").click(function(){
loadPage(this.className);
});
A stupid answer : create a <a> tag, and set its href attribute to the correct value.
Otherwise :
A standard way to store key: values pairs in javascript is to use a plain object :
var urls = {};
urls['about'] = 'mysuperduperurlforabout.html';
function loadPage(target) {
var url = urls[target];
//maybe check if url is defined ?
$('#dashboard').load(url);
}
$(".nav li").click(function(){
loadPage($(this).attr("class") + ".html");
});
or
$("#dashboard").load(target+".html");
You can call the variables like this (if that's what you asked):
var test = 'we are here';
var x = 'test';
console.log(window[x]);
It's similar to the $$ in PHP. The output will be:
we are here in the console window.
You could put the "about" as an object or array reference similar to:
var pageReferences = [];
pageReferences["about"] = "about.html";
var otherReference = {
"about": "about.html"
};
function loadPage(target) {
alert(pageReferences[target]);
alert(otherReference[target]);
$("#dashboard").load(target);
}
$(".nav li").click(function () {
loadPage($(this).attr("class"));
});
Both of these alerts will alert "about.html" referencing the appropriate objects.
EDIT: IF you wished to populate the object based on markup you could do:
var otherReference = {};
$(document).ready(function () {
$('.nav').find('li').each(function () {
var me = $(this).attr('class');
otherReference[me] = me + ".html";
});
});
You could even store the extension in an additional attribute:
var otherReference = {};
$(document).ready(function () {
$('.nav').find('li').each(function () {
var me = $(this).attr('class');
otherReference[me] = me + "." + $(this).attr("extension");
});
});
Better would be to simply put the page reference in a data element:
<li class="myli" data-pagetoload="about.html">Howdy</li>
$(".nav li").click(function () {
loadPage($(this).data("pagetoload"));
});
var pageReferences = {}; would be the appropriate thing for this purpose.
class="myclass about myotherclass"
