我正在为用户在其博客上放置一个小部件,以将流量引导至我的优惠券代码网站。我希望小部件访问数据库并输出当天的5张优惠券。以下是我将他们在其网站上放置:如何在javascript小部件中使用Mysql数据库数据
<script src="http://example.com/widget/script.js" type="text/javascript"></script>
<div id="example-widget-container"></div>
现在的script.js文件看起来像:
(function() {
// Localize jQuery variable
var jQuery;
/******** Load jQuery if not present *********/
if (window.jQuery === undefined || window.jQuery.fn.jquery !== '1.4.2') {
var script_tag = document.createElement('script');
script_tag.setAttribute("type","text/javascript");
script_tag.setAttribute("src",
"http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js");
script_tag.onload = scriptLoadHandler;
script_tag.onreadystatechange = function() { // Same thing but for IE
if (this.readyState == 'complete' || this.readyState == 'loaded') {
scriptLoadHandler();
}
};
// Try to find the head, otherwise default to the documentElement
(document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag);
} else {
// The jQuery version on the window is the one we want to use
jQuery = window.jQuery;
main();
}
/******** Called once jQuery has loaded ******/
function scriptLoadHandler() {
// Restore $ and window.jQuery to their previous values and store the
// new jQuery in our local jQuery variable
jQuery = window.jQuery.noConflict(true);
// Call our main function
main();
}
/******** Our main function ********/
function main() {
jQuery(document).ready(function($) {
/******* Load CSS *******/
var css_link = $("<link>", {
rel: "stylesheet",
type: "text/css",
href: "style.css"
});
css_link.appendTo('head');
/******* Load HTML *******/
var jsonp_url = "http://www.mydomain.com/widget_data.php";
$.getJSON(jsonp_url, function(data) {
$('#example-widget-container').html("This data comes from another server: " + data.html);
});
});
}
})(); // We call our anonymous function immediately
我遇到的问题是我如何返回一个JSON数组的js文件,以及如何循环输出无序列表,每个优惠券都是自己的列表项目?
任何帮助非常感谢!
你能告诉我如何使ajax请求?我最初使用jQuery和.getJSON函数,但我真的不喜欢它。谢谢! – PaperChase
在jQuery文档中添加了一个jQuery示例 –
