JS实现HTML表格排序功能
本文实例为大家分享了JavaScript实现HTML表格排序功能,供大家参考,具体内容如下
HTML代码:
<tablecellpadding="0"id="table"> <trclass="top"> <td>clickme</td> <td>clickme</td> <td>clickme</td> <td>clickme</td> </tr> <tr> <td> <spanid="bfn_la_bac.usa">15.43</span> </td> <tdclass="red">700</td> <td>1.220</td> <tdclass="red">阿</td> </tr> <tr> <td> <spanid="bfn_la_c.usa">7.05</span> </td> <tdclass="red">4</td> <td>3,000</td> <tdclass="red">炳</td> </tr> <tr> <td> <spanid="bfn_la_jpm.usa">30.62</span> </td> <tdclass="red">30</td> <td>2,558,800</td> <tdclass="red">和</td> </tr> <tr> <td> <spanid="bfn_la_axp.usa">22.30</span> </td> <tdclass="red">5</td> <td>6</td> <tdclass="red">瞎</td> </tr> <tr> <td> <spanid="bfn_la_mrk.usa">26.31</span> </td> <tdclass="red">0.6</td> <td>5</td> <tdclass="red">-</td> </tr> <tr> <td> <spanid="bfn_la_pg.usa">63.16</span> </td> <tdclass="red">7</td> <td>4</td> <tdclass="red">子</td> </tr> </table>
JavaScirpt代码:
vartableSort=function(){ this.initialize.apply(this,arguments); } tableSort.prototype={ initialize:function(tableId,clickRow,startRow,endRow,classUp,classDown,selectClass){ this.Table=document.getElementById(tableId); this.rows=this.Table.rows;//所有行 this.Tags=this.rows[clickRow-1].cells;//标签td this.up=classUp; this.down=classDown; this.startRow=startRow; this.selectClass=selectClass; this.endRow=(endRow==999?this.rows.length:endRow); this.T2Arr=this._td2Array();//所有受影响的td的二维数组 this.setShow(); }, //设置标签切换 setShow:function(){ vardefaultClass=this.Tags[0].className; for(varTag,i=0;Tag=this.Tags[i];i++){ Tag.index=i; addEventListener(Tag,'click',Bind(Tag,statu)); } var_this=this; varturn=0; functionstatu(){ for(vari=0;i<_this.Tags.length;i++){ _this.Tags[i].className=defaultClass; } if(turn==0){ addClass(this,_this.down) _this.startArray(0,this.index); turn=1; }else{ addClass(this,_this.up) _this.startArray(1,this.index); turn=0; } } }, //设置选中列样式 colClassSet:function(num,cla){ //得到关联到的td for(vari=(this.startRow-1);i<(this.endRow);i++){ for(varn=0;n<this.rows[i].cells.length;n++){ removeClass(this.rows[i].cells[n],cla); } addClass(this.rows[i].cells[num],cla); } }, //开始排序num根据第几列排序aord逆序还是顺序 startArray:function(aord,num){ varafterSort=this.sortMethod(this.T2Arr,aord,num);//排序后的二维数组传到排序方法中去 this.array2Td(num,afterSort);//输出 }, //将受影响的行和列转换成二维数组 _td2Array:function(){ vararr=[]; for(vari=(this.startRow-1),l=0;i<(this.endRow);i++,l++){ arr[l]=[]; for(varn=0;n<this.rows[i].cells.length;n++){ arr[l].push(this.rows[i].cells[n].innerHTML); } } returnarr; }, //根据排序后的二维数组来输出相应的行和列的innerHTML array2Td:function(num,arr){ this.colClassSet(num,this.selectClass); for(vari=(this.startRow-1),l=0;i<(this.endRow);i++,l++){ for(varn=0;n<this.Tags.length;n++){ this.rows[i].cells[n].innerHTML=arr[l][n]; } } }, //传进来一个二维数组,根据二维数组的子项中的w项排序,再返回排序后的二维数组 sortMethod:function(arr,aord,w){ arr.sort(function(a,b){ x=killHTML(a[w]); y=killHTML(b[w]); x=x.replace(/,/g,''); y=y.replace(/,/g,''); switch(isNaN(x)){ casefalse: returnNumber(x)-Number(y); break; casetrue: returnx.localeCompare(y); break; } }); arr=aord==0?arr:arr.reverse(); returnarr; } } /*-----------------------------------*/ functionaddEventListener(o,type,fn){ if(o.attachEvent){ o.attachEvent('on'+type,fn); }elseif(o.addEventListener){ o.addEventListener(type,fn,false); }else{ o['on'+type]=fn; } } functionhasClass(element,className){ varreg=newRegExp('(\s|^)'+className+'(\s|$)'); returnelement.className.match(reg); } functionaddClass(element,className){ if(!this.hasClass(element,className)){ element.className+=""+className; } } functionremoveClass(element,className){ if(hasClass(element,className)){ varreg=newRegExp('(\s|^)'+className+'(\s|$)'); element.className=element.className.replace(reg,''); } } varBind=function(object,fun){ returnfunction(){ returnfun.apply(object,arguments); } } //去掉所有的html标记 functionkillHTML(str){ returnstr.replace(/<[^>]+>/g,""); } //------------------------------------------------ //tableid第几行是标签行,从第几行开始排序,第几行结束排序(999表示最后)升序标签样式,降序标签样式选中列样式 //注意标签行的class应该是一致的 varex1=newtableSort('table',1,2,999,'up','down','hov');
