Jquery progress bar

Jquery progress bar is a progress bar plug-in developed based on jquery, adhering to jquery's simple philosophy. Not only easy to use, but also easy to customize the appearance. For projects that use the jquery framework, it is a good choice to use the progress bar control.

The jquery progress bar is the same as the regular plug-in. You only need to use the selector to select an HTML element and directly call the open method of the plug-in. It provides the public method named progressbar (). Then, when there is an element with the ID of progress1 on the HTML page, you can initialize the control as follows:

$ ("# Progress1"). progressbar ();

Its constructor can receive parameters shown in the following table.

The Config parameter is a hash object that contains the following attributes used to set the appearance characteristics of the progress bar.

Attribute	Purpose
Increment	Set the growth of each step of the progress bar. The default value is 2.
Speed	Set the speed of the Dynamic Sliding effect during progress bar initialization. The default value is 15. The larger the value, the slower the sliding speed.
Showtext	Set whether to display the percentage identifier text. The default value is true, indicating that the percentage text mark is displayed.
Boximage	Set the border image. The default value is images/progressbar.gif. To customize the border, modify this attribute and point to the image to be used.
Barimage	Set the progress icon image. The default value is images/progressbg_green.gif. To customize the image, modify the attribute and point to the image to be used. This image is classified into two sections. The first half is used to identify the progress, and the last half is used to identify the remaining progress. The two sections are of the same length and are equal to the width of the progress bar.
Width	Set the width of the progress bar. This value must be consistent with the image pointed to by barimage and boximage. The default value is 120.
Height	Set the height of the progress bar. This value must be consistent with the image pointed to by barimage and boximage. The default value is 12.

The interaction with the server will not be discussed here, just use ajax to get the progress value from the server, and then use progressbar (persent) to update the progress.
