Chrome plugin development (d)

In front of us write three more practical plug-in, in practical work, we also use many other plug-ins, such as Denver, Pocket and the like, we may need to enable or disable plug-ins or often removing the plug, if every time more should point to tools -> extensions program to do these operations will be very upset, this section we will achieve a convenient plug-in management plug-in, we take a look at the screenshot plugin running:

 

Plug-in implementation of the other plug-ins to enable / disable / remove function, the following us look at how to achieve this plug.

The old rules, before the formal start writing, we need to first look at the API:

1, chrome.management.getAll return all installed extensions

2, chrome.management.get obtain detailed information on a plug according to the ID

3, chrome.management.setEnabled enable / disable a plug-in

4, chrome.management.uninstall remove a plug-in has been installed from the list

For information on using chrome.management related to the API, you can refer to: http://open.chrome.360.cn/extension_dev/management.html

Because we use chrome.management related API, so we need to apply management rights in the manifest.json file.

Then we started to write plug-ins, first of all we need to render plug-in list, of course, exclude themselves, or accidentally disabled or removed itself, it also manages a hair, we are here to exclude themselves by the plug-in name, first of all we first define two variables:

1 var $list = $('#list');
2 var currentExtensionName = 'ExtensionManagement';

$ List container node is rendered, the current name of the plugin currentExtensionName definition, then, we get all the installed plug exclude themselves and others render other plug-ins.

 1 chrome.management.getAll(function(eInfo){
 2   var list = eInfo.map(function(ex) {
 3     if (ex.name === currentExtensionName) {
 4     return '';
 5   }
 6   var activeClass = ex.enabled ? 'fa-times' : 'fa-check';
 7   return '<li id="' + ex.id + '"><a href="' + 'javascript:void(0)" title="' + ex.shortName + '">' + ex.shortName + '</a><div class="icons"><span class="fa able ' + activeClass + '"></span><span class="fa trash fa-trash-o"></span></div></li>';
 8   });
 9   $list.html(list.join(''));
10 });

Now we have to plug rendered to the page, and add the enable / disable / remove links, etc. according to their state, then we need to implement to enable / disable / remove features such as the.

 1 $list.on('click', '.able', function() {
 2   var _this = $(this),
 3     _id = _this.parents('li').attr('id');
 4   chrome.management.get(_id, function(eInfo) {
 5     if (eInfo.enabled) {
 6       chrome.management.setEnabled(_id, false, function() {
 7       _this.removeClass('fa-times').addClass('fa-check');
 8       });
 9     } else {
10       chrome.management.setEnabled(_id, true, function() {
11       _this.removeClass('fa-check').addClass('fa-times');
12       });
13     }
14   });
15 });
16  
17 $list.on('click', 'a', function() {
18   var _this = $(this),
19     _li = _this.parents('li'),
20     _able = _li.find('.able'),
21     _id = _li.attr('id');
22   chrome.management.get(_id, function(eInfo) {
23     if (eInfo.enabled) {
24       chrome.management.setEnabled(_id, false, function() {
25       _able.removeClass('fa-times').addClass('fa-check');
26       });
27     } else {
28       chrome.management.setEnabled(_id, true, function() {
29       _able.removeClass('fa-check').addClass('fa-times');
30       });
31     }
32   });
33 });
34  
35 $list.on('click', '.trash', function() {
36   var _this = $(this),
37     _li = _this.parents('li'),
38     _id = _li.attr('id');
39   chrome.management.uninstall(_id, function() {
40     if (chrome.runtime.lastError) {
41       console.log(chrome.runtime.lastError.message);
42     } else {
43       _li.fadeOut('normal', function() {
44         _li.remove();
45       });
46     }
47   });
48 });

The above is the idea of ​​how we achieve, let's look at the directory structure:
