Two methods that are equally applicable to intercepting long HTML text containing HTML code_javascript skills

Method 1: Use CSS to truncate the string: IE, FireFox, Opera, and Safari are all compatible

Copy code The code is as follows:

.subLongText{
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*/
}
Any length text

Method 2: Use js to intercept

Copy the code The code is as follows:

$.fn.substr = function(length,content){
$(this).each(function(i,item){
var val=$ (item).html();
if(!val) return;
if(val.length>length) {
val = val.substring(0,length);
val = content || "..."
$(item).html(val);
}
});
}
function subTdContent(){
$('td' ).substr(20);
}





My code: $.fn.substr = function(l,c){ $(this).each(function(i,item)
