I'm using the following code to to produce a content area that opens and closes on click, with a plus/minus image that also toggles depending on state of content area. What I would like to do is add a jquery cookie that saves the state of the content area - how would I achieve this please? S
$(document).ready(function() {
$("a.toggle").click(function() {
var img = $(this).find("img"); //get a handle of the image tag inside title link
var src = $(img).attr("src"); //get the source of the image
//toggle the source of the image to show either plus/minus
if (src.endsWith("search_open.jpg"))
src = src.replace('search_open.jpg', 'search_close.jpg');
else
src = src.replace('search_close.jpg', 'search_open.jpg');
$(img).attr("src", src);
//get the title of the anchor tag which corresponds to the id of the content div
var content = $(this).attr("title");
$(content).toggle();
});
});
String.prototype.endsWith = function(str) {
return this.lastIndexOf(str) == this.length - str.length;
}
Edit: final code/solution
$(document).ready(function() { 开发者_如何学JAVA
$("a.toggle").each(function () {
var img = $(this).find("img");
var src = $(img).attr("src");
var content = $(this).attr("title");
var isVisible = $.cookie('content');
if (isVisible == 'true') {
$(content).show();
src = src.replace('search_open.jpg', 'search_close.jpg');
}
$(img).attr("src", src);
});
$("a.toggle").click(function() {
var img = $(this).find("img"); //get a handle of the image tag inside title link
var src = $(img).attr("src"); //get the source of the image
//toggle the source of the image to show either plus/minus
if (src.endsWith("search_open.jpg"))
src = src.replace('search_open.jpg', 'search_close.jpg');
else
src = src.replace('search_close.jpg', 'search_open.jpg');
$(img).attr("src", src);
//get the title of the anchor tag which corresponds to the id of the content div
var content = $(this).attr("title");
$(content).toggle();
$.cookie('content', $(content).is(':visible'));
});
});
String.prototype.endsWith = function(str) {
return this.lastIndexOf(str) == this.length - str.length;

Use jQuery.cookie
plugin to work with cookies. Store and get necessary data using it.
https://github.com/carhartl/jquery-cookie
Checkout test examples in the project:
https://github.com/carhartl/jquery-cookie/blob/master/test.js
$.cookie('c') // get cookie value
$.cookie('c', 'my value') // set cookie value
You will need to strore some marker (probably some autoincremental id) for each section you toggled, and then on $(document).ready(..)
you will need to read and resotre state of these sections.
$(document).ready(function () {
$("a.toggle").each(function () {
var content = $(this).attr("title");
var isVisible = $.cookie(content);
if (isVisible) {
$(content).show();
}
});
$("a.toggle").click(function () {
var img = $(this).find("img"); //get a handle of the image tag inside title link
var src = $(img).attr("src"); //get the source of the image
//toggle the source of the image to show either plus/minus
if (src.endsWith("search_open.jpg"))
src = src.replace('search_open.jpg', 'search_close.jpg');
else
src = src.replace('search_close.jpg', 'search_open.jpg');
$(img).attr("src", src);
//get the title of the anchor tag which corresponds to the id of the content div
var content = $(this).attr("title");
$(content).toggle();
$.cookie(content, $(content).is(':visible'));
});
});
String.prototype.endsWith = function (str) {
return this.lastIndexOf(str) == this.length - str.length;
}
Yes you could use jQuery.cookie.
$("a.toggle").click(function() {
var img = $(this).find("img"); //get a handle of the image tag inside title link
var src = $(img).attr("src"); //get the source of the image
//toggle the source of the image to show either plus/minus
if (src.endsWith("search_open.jpg"))
src = src.replace('search_open.jpg', 'search_close.jpg');
else
src = src.replace('search_close.jpg', 'search_open.jpg');
$(img).attr("src", src);
//get the title of the anchor tag which corresponds to the id of the content div
var content = $(this).attr("title");
$(content).toggle();
//this saves a string with true or false depending on the visibility
//of your element. i use the title of the element as name for the cookie so that you can save more than one
$.cookie(content, $(content).is(':visible') );
});
});
