Under normal circumstances, it is not easy for you to quickly record the information of a member on the member search result page, you may right-click the member photo and write down the home address of the Member. If you want to add more members to the favorites page, repeat the above operations. The default search result page displays the following results:

After installing the Greasemonkey script that I wrote, the search result page changes a bit. The "Write to me" button changes to the "add to Favorites" check box. The result is as follows, note the differences between the red box logo and the preceding image:

Now, if you want to add the information about two beautiful women to the right of the first row, click the "add to Favorites" check box (if you don't want to add a favorite, click Cancel again ), in this way, the HTML of the selected member information is generated in the text box at the page flip of the footer, and is selected by default. You can right-click it and copy it, for example:

The member file is the record file of your favorite member. The result is as follows:

The code of the jiayuan.html template file is as follows. copy it and save it as an html Suffix in notepad.

Ii. install and use scripts

To use this script function, you must install the Firefox browser, which is installed with the Greasemonkey plug-in, and then can find JiaYuan locally or on the network. user. js script file (the Greasemonkey script I wrote, and the code will be provided later), then pull the JS script locally to the browser window, or access the JS script (JiaYuan. user. js), the script installation interface will pop up, such:

After successfully installing the browser and plug-in, as well as the script, visit the members of The jiayuan network search table single page: http://search.jiayuan.com,
Submit a search request.

If yes, the Greasemonkey plug-in is successfully installed, for example:

Iv. Script Preview

Greasemonkey scripts are all written in JavaScript. To Write Excellent Greasemonkey applications, you must be familiar with JavaScript programming, understand JavaScript DOM programming, and analyze the HTML code structure. If you want to learn more about Greasemonkey, read Greasemonkey. Below I will publish the script code for this application as follows, hoping to serve as a reference for everyone.

The Code is as follows:

PageBox. appendChild (loveCodeDom );
$ ('Lovecode'). style. width = '640px ';
$ ('Lovecode'). style. margin = '10px ';
}

Var loveCheckBoxs = document. getElementsByName ('love ');
For (var I in loveCheckBoxs)
{
// Only the member information checked by the check box is output.

5. Notes

1. When installing the Greasemonkey plug-in to the Firefox browser, select the Greasemonkey plug-in corresponding to the browser version. We recommend that you download the "enhanced portable version" Firefox browser. This version is generally integrated with the Greasemonkey plug-in. Download reference link: http://www.jb51.net/softs/21957.html

2. The script provided in this article may expire with the revision of jiayuan. Because the Greasemonkey script is operated based on the HTML of the target website, please leave a message if you find that the script is invalid, let me fix it. Of course, if you will write the script, you can also manually modify, modify the method can refer to here, modify the user Script: http://www.firefox.net.cn/dig/helloworld/editing.html

3. It is understood that many browsers now support Greasemonkey, such as Chrome, Opera, and even IE. This script has not been tested on these browsers, if you find a problem with the script on another browser platform, you can leave a message to tell me.

4. Make sure that the Greasemonkey plug-in is activated, that is, the "monkey" icon in the lower right corner of the browser is not gray. Otherwise, even if you install the plug-in, you will not get the expected effect.
