Implementation of page jump and loading external pages in jQuery mobile web development_jquery

changePage() page jump

jQuery.mobile.changePage( to [, options ] )

To jump from one page to another, use the changePage method of the $.mobile object. But to use this method, you have to click a link or submit a form. This method has two parameters.

to: It is the first parameter, it is necessary and indispensable. Type: string or object.

String: Absolute or relative URL address. For example: ("about/us.html")

Object:
jquery selector object, such as: ($("#about")).
An array [from, to] that specifies two page references, used to jump to a known page. From is the currently visible page (or $.mobile.activePage).
Object to send form data, such as ({to: url, data: serialized form data, type: "get" or "post"}.

options: It is the second parameter and is optional. Type: Object

allowSamePageTransition (boolean, default: false)
By default, changePage() ignores requests to jump to an already active page. If this is set to true, it will be executed. Developers should note that some page transitions will assume that the source page and the target page in a request to jump to a page are different, so there will be no transition animation.

changeHash (boolean, default: true)
Determines whether the address bar hash should be updated.

data (string or object, default: undefined)
The data to be sent via ajax request is only available when the to parameter of changePage() is an address.

dataUrl (String, default: undefined)
The URL address of the browser address is updated when the page conversion is completed. If not specified, the data-url attribute value of the page is used.

pageContainer (jQuery selector, default: $.mobile.pageContainer) specifies the container that should contain the page.

reloadPage (boolean, default: false)
Force refresh of the page, even when the DOM element in the page container is ready. Only available when the to parameter of changePage() is an address.

reverse (boolean, default: false)
Set the direction of the page transition animation. When set to true, it will cause the transition in the opposite direction.

role (string, default: undefined)
Use the data-role value when displaying the page. By default this parameter is undefined, meaning it depends on the element's @data-role attribute.

showLoadMsg (Boolean value, default: true) Set whether to display loading information when loading external pages.

transition (String, default: $.mobile.defaultPageTransition) Transition when using the displayed page.

type (string, default: get)
Specify the method used when requesting the page ("get" or "post"). Only available when the to parameter of changePage() is an address.

//以slideup效果 跳转到 "about us" 页面

$.mobile.changePage("about/us.html", "slideup"); 
//以pop效果 跳转到 "confirm" 页面 并且在url hash里不记录其历史

$.mobile.changePage("../alerts/confirm.html"， "pop"， false， false); 
//跳转到 "search results" 页面，提交id为 "search"的表单数据

$.mobile.changePage({url:"searchresults.php" , type:"get" , data: $("form#search").serialize() }); 
//将页面url，类型，数据定义为变量来传递。

var pageData = { url: formresults.php, type: 'get', data:$('form#myform').serialize () };

$.mobile.changePage(pageData);
//使用changepage来加载第三个页面

var previousPage = $.mobile.activePage.data ('ui.prevPage');

$.mobile.changePage([previousPage, anotherPreviousPage], 'pop');
