Question

我是javascript的新手。我在HTML表中遇到问题。（这只是一个参考，因为整个表格的范围是100,000到2,000,000。）

这是一个列表，它有点大，如果我输入一个“范围”错误，手动创建这个将需要很长时间，我将不得不编辑并重新安排，然后检查“范围”是否正确再次。我希望这可以在javascript中完成。任何人都可以帮我把“范围”变成“r-1和r-2”之类的变量，一个函数可以自动将变量增量填充到5,000或10,000，从100,000到2,000,000。

Answer 1

这将构建显示的表结构

 $(function(){ 
     /* start & end divided by 1000*/
    var start=100, end=2000, increment=25, rowCellCount=4;;
    var html=[];
    for(i=start; i<= end- (increment*rowCellCount)+increment ; i=i+5){
        html.push('<tr>');
        for( j=0; j< rowCellCount; j++){
            var valueStart= (i+j*increment), valueEnd=valueStart+5;

            var text= parseThousands(valueStart)+',000 ';
            text+= valueEnd <= end ? ' - ' + parseThousands(valueEnd)+',000' :'';        

            html.push( '<td class="range" width="15%">'+text+'</td><td class="value" width="10%">VALUE</td>');
         }
         html.push('</tr>');
    }

    $('table').html( html.join(''))

 });

    function parseThousands( val){
        var txt =val.toString();
        if( txt.length==4){       
             txt= txt.slice(0,1) +','+ txt.slice(1)       
        }
        return txt;
    }

Answer 2

不确定。旧代码变得多余，所以我删除了它。查看jsFiddle：http://jsfiddle.net/WFqTX/4/

您现在可以控制开始，结束，步骤和所有其他参数：

    /* here we define variables to dynamically create your
    data, so you don't have to write it manually */

    var start = 100000;
    var end = 125000;
    var step = 5000;

    /* for additional variability we will set number of
    columns as a variable */

    var colN = 4;

使用Javascript或jQuery在HTML表中自动增加数据
