We often see that many articles on the website can customize the font size and medium size. Below I would like to recommend a js control text display code for you. If you need it, you can refer to it.
Javascript control text display
| The Code is as follows: | Copy code |
<Html> |
|
Jqeury Implementation Method
The home page is in the HTML section:
| The Code is as follows: | Copy code |
| <Ul id = "resizer"> <Li id = "f_text"> font size: </li> <Li id = "f_s"> <a href = "javascript: void (0)"> small </a> </li> <Li id = "f_m"> <a href = "javascript: void (0)"> medium </a> </li> <Li id = "f_l"> <a href = "javascript: void (0)"> large </a> </li> </Ul> |
|
Next, don't forget to introduce the jQuery library. Let's just say a few simple lines of code:
| The Code is as follows: | Copy code |
| $ (Document). ready (function (){ $ ('# Resizer li'). click (function (){ Var fontSize = 1.4; Var name = $ (this). attr ('id '); If (name = 'f _ s '){ FontSize:-= 0.1 } Else if (name = 'f _ L '){ FontSize ++ = 0.1 } Else if (name = 'f _ m '){ FontSize = 1.4 } $ ('. Entry p'0000.css ('font-size', fontSize + 'em') // '. entry P' is the selector of the body to be controlled. }); }); |
|
The code is still very simple. I like it to be streamlined, but the effect is obvious. It is also very easy to understand, because I use the unit em in the font of the entire site, so the above jQuery code is also in the unit em, we recommend that you use em as the font unit.
