    /* $ (". Test1"). wordLimit (); the css width is automatically obtained for processing. If no width is specified for. test1 in css, it does not work.
    $ (". Test2"). wordLimit (24); number of truncated characters. The value is an integer greater than 0. Here, the number of characters in the tag of class test2 can be 24 at most.
    (Function ($ ){
    $. Fn. wordLimit = function (num ){
    This. each (function (){
    If (! Num ){
    Var copyThis = certificate (this.clonenode(true?#.hide().css ({
    'Position': 'absolute ',
    'Width': 'auto ',
    'Overflow': 'visible'
    $ (This). after (copyThis );
    If (copyThis. width ()> $ (this). width ()){
    $ (This). text ($ (this). text (). substring (0, $ (this). text (). length-4 ));
    Certificate (this).html((this).html () + '...');
    CopyThis. remove ();
    $ (This). wordLimit ();
    } Else {
    CopyThis. remove (); // clear the copy
    } Else {
    Var maxwidth = num;
    If ($ (this). text (). length> maxwidth ){
    $ (This). text ($ (this). text (). substring (0, maxwidth ));
    Certificate (this).html((this).html () + '...');
    }) (JQuery );
