Homemade lightweight jQuery.boxy dialog plug-in code_jquery

In this regard, the jquery.boxy plug-in has been made very powerful. Commonly used prompts, confirmations, dragging, changing sizes, and asynchronous loading are all very practical, resulting in larger files (negligible), and many functions are not needed. For this reason , with the attitude and idea of ​​learning and practicing at the same time, I made a lightweight pop-up layer plug-in suitable for this project. This is the first time I write a jqeury plug-in, and I am also preparing to encapsulate common operations into jquery plug-ins in the future. Bar.

First of all, let’s give the plug-in a name so that it can fool people. Let’s call it jquey.cvbox.min.js. cv is the abbreviation of the website domain name ChinaValue. The compressed capacity is controlled below 6K. Since it's not finished yet, I'll write down my thoughts first.

1. Add container elements to the page to display content, as well as the background of the pop-up layer. It only needs to be there. As for where you were born (that is, where it is displayed on the page) and what you will grow into. The appearance will be cultivated (set up) later, and the appearance will naturally be dressed up by the art director.
2. According to our needs, we define some commonly used objects in advance, such as the background of the mask, the container of the pop-up layer, the title bar of the pop-up layer, the content area of ​​the pop-up layer, and the height of the current browser window. Kuan, etc., with these, it will be much more convenient to use later.
3. Start stuffing content into the container. The content can be a prompt (corresponding to the prompt function), a question (corresponding to the confirmation box), a picture (for example, for enlarging a small picture), or It is a piece of HTML code (replacing the inconvenience of writing HTML directly in JS).
4. Define the event that the user clicks to close, that is, hiding or removing the background layer and pop-up layer, leaving it to be called when the operation is completed.
5. Set the background layer transparency and scroll height, set the position of the pop-up layer, center it with scrolling or be fixed.
6. Finally, in order to facilitate use in multiple situations, extract variable parameters. The parameters must have default values, and use $.extend to complete it.

The beta version is expected to be released after the holidays, and it will be unabridged.

Complete test code

Copy code The code is as follows:

未压缩版本是6K大小，压缩后只有2K大，应该算很轻了。

 

1.弹出提示框，点击查看效果。

$(this).cvbox({ <br>titleBarText: "弹出提示框", <br>alertText: "世界上最远的距离不是生与死的距离<br />而是我在你面前<br />你却不知道我爸爸是李刚" <br>}); <br>

2. 효과를 보려면 클릭하세요.

$("# A2").click(function() { <BR>$(this).cvbox({ <BR>titleBarText: "팝업 프롬프트 상자는 1초 후에 자동으로 닫힙니다.", <BR>alertText: "가장 먼 거리 세상에는 삶과 죽음의 거리가 없습니다<br /&gt ;하지만 나는 당신 앞에 있습니다<br />당신은 내 아버지가 리강이라는 것을 모르고 있습니다", <BR>delayClose:1000 <BR> }); <BR>

3. 대화 상자가 나타나면 클릭하여 효과를 확인하세요.
