问题:

Basicily i have a index.html shown below..

<html>

<head>

<title>UI Test: Main Menu</title>

<script type="text/javascript" src="jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="general.js"></script>

</head>

<body>  

<input type="button" value="Details" onclick="javascript:$('#mainContainer').load('loadpage.html #name1div *');"/><br>
<div id="mainContainer">        

</div>

The loadpage.html cotaints

<div id="nav1div><h3>1 DIV </h3> </div>
<div id="nav2div><h3>2 DIV </h3> </div>
<div id="nav3div><h3>3 DIV </h3> </div>
<div id="nav4div><h3>4 DIV </h3> </div>

And my objective is to basicly load 1 of the divs at a time in to the main container, i know the load function can load the full page at once but this is NOT what i need to do.

Had a few look at similar questions but cant seem to resolve this..

All help is appreciated thanks guys!

回答1:

The jQuery .load() function allows you to specify a portion of a page to load, rather than just the whole document.

e.g.

$('#mainContainer').load('loadpage.html #nav1div');

Check out the jQuery load() documentation particularly where it regards “Loading Page Fragments”.



回答2:

To load DIVs one after another, define a counter

var curDiv = 1; // current Div

somewhere at the beginning (better to define a $(document).ready() function to initialize it). Define this function:

function loadThing()
{
    if (curDiv<5) $('#mainContainer').load('loadpage.html #nav' + (curDiv++) + 'div');
}

Define the click event like:

$("input#getdiv").click(loadThing);

and you button like:

<input id="getdiv" type="button" value="Details" />

With every click you should get first div, second, and so on.

With this approach you separate JS from HTML, which is always good.

jQuery load can easily load page fragments, like so

$('#mainContainer').load('loadpage.html #nav1div');
