When using jquery mobile development, sometimes we need to display the load prompt box during the request for Ajax (for example: a rotated picture + a hint: loading ... ）。 This time, we can manually display the jquery mobile loader, the approximate process is as follows:

1. Boot loader, display "Loading ...";

2. Make an AJAX request, update the page data after the request is completed, and refresh the jquery mobile control style;

3. Close the loader.

Here's how to manually display the loader in jquery Mobile 1.2.0 and 1.1.0 (very simply, a few lines of code will be OK!). ）。

The first is the jQuery Mobile 1.2.0 Reference:

[HTML]View Plaincopy
  2. <! DOCTYPE HTML>
  4. <html>
  6. <head>
  8. <title>ajax test </title>
  10. <meta charset="GBK">
  12. <meta name="viewport" content="width=device-width, initial-scale=1">
  14. <!--from the official downloaded file in the project's Jquery-mobile directory --
  16. <link rel= "stylesheet" href="jquery-mobile/jquery.mobile-1.2.0.min.css"/>
  18. <link rel= "stylesheet" href= "jquery-mobile/jquery.mobile.structure-1.2.0.min.css " />
  20. <script src="Jquery-mobile/jquery-1.8.2.min.js"></script>
  22. <script src="Jquery-mobile/jquery.mobile-1.2.0.min.js"></script>
  24. <head>

Write JavaScript functions:

[JavaScript]View Plaincopy
  2. <script>
  4. Display Loader
  6. function Showloader () {
  8. //Display loader. For jQuery Mobile 1.2.0
  10. $.mobile.loading (' show ', {
  12. Text: ' loading in ... ', //loader display
  14. Textvisible: True, //Whether the text is displayed
  16. Theme: ' A ', //loader theme style A-e
  18. TextOnly: false, //Whether only text is displayed
  20. HTML: "" //HTML content to display, slices, etc.
  22. });
  24. }
  28. Hides the loader. For JQuery Mobile 1.2.0
  30. function Hideloader ()
  32. {
  34. //Hide Loader
  36. $.mobile.loading (' hide ');
  38. }
  40. </script>

Prepare two buttons, one for the launcher (display) loader, and one for the Stop (hide) Loader:

[HTML]View Plaincopy
  2. <body>
  4. <div data-role="page">
  6. <!--head --
  8. <div data-role="header">
  10. <h3>ajax test </h3>
  12. </div>
  14. <!--content --
  16. <div data-role="Content">
  18. <h3>ajax test </h3>
  22. <input type="button" value="show Ajax loader" onclick="Showloader ()"/>
  24. <input type="button" value="Hide ajax loader" onclick="Hideloader ()"/>
  28. </div>
  30. </body>

The effect is as follows (subject: ' A '):

Of course, you can adjust the $.mobile.loading (' show ', {...} Experiment with different loader effects in the parameters.

for details of the loader, see the jquery Mobile 1.2.0 official demo demo :

Http://jquerymobile.com/demos/1.2.0/docs/pages/loader.html

Note: The Ajax loader shown in JQuery Mobile1.1.0 is completely different from the 1.2.0 version! Hang Daddy!

The code for the JQuery Mobile 1.1.0 display loader is as follows:

[JavaScript]View Plaincopy
  2. <script>
  4. //Display loader
  6. function Showloader () {
  8. //Display loader. For jQuery Mobile 1.1.0
  10. $.mobile.loadingmessage = ' loading in ... '; //display of text
  12. $.mobile.loadingmessagetextvisible = true; //Whether to display text
  14. $.mobile.loadingmessagetheme = ' a '; //loader theme style A-e
  16. $.mobile.showpageloadingmsg (); //Display loader
  18. }
  22. //Hide loader. For jQuery Mobile 1.1.0
  24. function Hideloader () {
  26. //Hide Loader
  28. $.mobile.hidepageloadingmsg ();
  30. }
  32. </script>

The effect of the display is quite similar.

The description of 1.1.0 in the official 1.2.0 documentation is as follows:

The page Loading dialog is previously configured globally with three settings
$.mobile.loadingmessage,
$.mobile.loadingmessagetextvisible, and
$.mobile.loadingmessagetheme
Which is now deprecated. In addition to the methods for showing and hiding,
$.mobile.showpageloadingmsg and
$.mobile.hidepageloadingmsg is also deprecated.

This means: in 1.2.0, the $.mobile.showpageloadingmsg and $.mobile.hidepageloadingmsg are not used to display the loader.
