在一页（API 页面）上，我有一个这样的 PHP 数组：
$arr = array("headline1" =>
array("name" => "Headline 1",
"description" => "Description of headline 1",
"items" => array(
array("name"=>"John", "lastname"=>"Doe"),
array("name"=>"Peter", "lastname"=>"Pan")
)
),
"headline2" => array("name" => "Headline 2",
"description" => "Description of headline 2",
"items" => array(
array("name"=>"Alexander", "lastname"=>"Doe"),
array("name"=>"Steven", "lastname"=>"Smith")
)
),
"headline3" => array("name" => "Headline 3",
"description" => "Description of headline 3",
"items" => array(
array("name"=>"John", "lastname"=>"Doeh"),
array("name"=>"Peter", "lastname"=>"Pans")
)
)
);
并且脚本从这个数组创建 json 编码版本：
echo json_encode($arr);
所以，我的问题是其他页面上的javascript。我想使用 jQuery $.getJSON 函数来检索这些数据并使 var 像这样：
var categoryData = {
headline1: {
name: "Headline 1",
description: "Description of headline 1",
items: [
{
name: "John",
lastname: "Doe"
},
{
name: "Peter",
horoscope: "Pan"
}
]
},
headline2: {
name: "Headline 2",
description: "Description of headline 2",
items: [
{
name: "Alexander",
lastname: "Doe"
},
{
name: "Steven",
horoscope: "Smith"
}
]
},
headline3: {
name: "Headline 3",
description: "Description of headline 3",
items: [
{
name: "John",
lastname: "Doeh"
},
{
name: "Peter",
horoscope: "Pans"
}
]
}
};
如何使用 jQuery $.getJSON 函数实现这一点？
编辑 ：
我的其他 Javascript 函数（jQuery 移动函数）
function showCategory( urlObj, options )
{
var categoryData = [];
$.getJSON('http://localhost/tst/sig.php', function(json) {
categoryData = json;
});
var categoryName = urlObj.hash.replace( /.*category=/, "" ),
// Get the object that represents the category we
// are interested in. Note, that at this point we could
// instead fire off an ajax request to fetch the data, but
// for the purposes of this sample, it's already in memory.
category = categoryData[ categoryName ],
// The pages we use to display our content are already in
// the DOM. The id of the page we are going to write our
// content into is specified in the hash before the '?'.
pageSelector = urlObj.hash.replace( /\?.*$/, "" );
if ( category ) {
// Get the page we are going to dump our content into.
var $page = $( pageSelector ),
// Get the header for the page.
$header = $page.children( ":jqmData(role=header)" ),
// Get the content area element for the page.
$content = $page.children( ":jqmData(role=content)" ),
// The markup we are going to inject into the content
// area of the page.
markup = "<p>" + category.description + "</p>",
// The array of items for this category.
cItems = category.items,
// The number of items in the category.
numItems = cItems.length;
// Generate a list item for each item in the category
// and add it to our markup.
for ( var i = 0; i < numItems; i++ ) {
markup += "<div data-role='collapsible' data-theme='a' data-content-theme='e'><h3>" + cItems[i].name + "</h3><p>"+ cItems[i].horoscope +"</p></div>";
}
markup += "</ul><p><a href='#one' data-rel='back' data-role='button' data-inline='true' data-icon='back'>Vratite se nazad</a></p> ";
// Find the h1 element in our header and inject the name of
// the category into it.
$header.find( "h1" ).html( category.name );
// Inject the category items markup into the content element.
$content.html( markup );
// Pages are lazily enhanced. We call page() on the page
// element to make sure it is always enhanced before we
// attempt to enhance the listview markup we just injected.
// Subsequent calls to page() are ignored since a page/widget
// can only be enhanced once.
$page.page();
// Enhance the listview we just injected.
$content.find( ":jqmData(role=collapsible)" ).collapsible();
$content.find( ":jqmData(role=button)" ).button();
// We don't want the data-url of the page we just modified
// to be the url that shows up in the browser's location field,
// so set the dataUrl option to the URL for the category
// we just loaded.
options.dataUrl = urlObj.href;
// Now call changePage() and tell it to switch to
// the page we just modified.
$.mobile.changePage( $page, options );
}
