Intercepts the specified length string length code instance:
The length of the string in the default state is often not able to meet the requirements, such as the length of news list news headlines, if too long tend to cause a line change, affect aesthetics, and then a user experience, so need to intercept the string length according to need, the following share can realize this function on both ends of the code, I hope to help everyone.
The code examples are as follows:
A. css method:
HTML code:
<class= "Cuttext"> ant Tribe welcomes you, only struggle will have a good tomorrow! </ Div >
CSS code:
. Cuttext{width:150px;Height:24px;Overflow:Hidden;White-space:nowrap;Text-overflow:ellipsis;Text-overflow:ellipsis;/*Ie/safari*/-ms-text-overflow:ellipsis;-o-text-overflow:ellipsis;/*Opera*/-moz-binding:URL ("ellipsis.xml#ellipsis");/*FireFox*/}
This method specifies the length, if this length is exceeded, is indicated by an ellipsis.
Two. jquery intercepts the string:
<!DOCTYPE HTML><HTML><Head><Metahttp-equiv= "Content-type"content= "text/html; charset=utf-8"><Metaname= "Author"content= "http://www.softwhy.com/" /><title>Intercept string length-ant tribe</title><styletype= "Text/css">ul{width:300px;Height:300px;margin:0px Auto;List-style:None;}ul Li{Height:30px;Line-height:30px;font-size:12px;}</style><Scripttype= "Text/javascript"src= "Mytest/jquery/jquery-1.8.3.js"></Script><Scripttype= "Text/javascript">$.fn.substr=function(length,content) {$ ( This). each (function(i,item) {varVal=$ (item). HTML (); if(!val)return; if(Val.length>length) {Val=val.substring (0, length); Val+=content||"..."; $ (item). HTML (val); } })} functionSubtdcontent () {$ ('Li'). substr ( -); } $ (document). Ready (function() {subtdcontent ();})</Script> </Head> <Body> <ul> <Li>Ant Tribe welcomes you, only struggle will have a better tomorrow</Li> <Li>Every day is a new one, so take a good hold of it.</Li> <Li>Never think of tomorrow, for the present is the most real.</Li> <Li>No one is a master in the beginning, all from the rookie grew up</Li></ul></Body> </HTML>
The above code can also achieve the interception of string length effect, how to implement this is not introduced here, if there are any questions can be posted message.
