请帮我看一下下面代码怎么按按钮后文本框的数字不会改变的？

你的Input命名怎么那么乱阿，主要是对象无法取得
还有对于对象的访问,不应该是如此的,这个代码太乱了

  3.   

    input不可以用数组型式命名吗？
      

  4.   

    function up(ballup){
             
             mun=parseInt(ballup.value)
             mun=mun+0.25
             ballup.value=mun
    }
    <input type="text" name="tigera" value="12" size="6"><br><input type="button" name="buttonup[1]" value="上" onclick="up(tigera)">我只是给你改了一个,其他的你自己改把!
      

  5.   

    function down(balldown){
             mun=parseInt(balldown.value)
             mun-=0.25
             balldown.value=mun
    }
    //-->注意这个应该是down()方法
      

  6.   

    而且tiger[1]这么命名好像是不成的！
    参数传不过去！
      

  7.   

    这样可以用了：）

    把你的up和down函数用下面两个函数覆盖就OK，我调试过了：）
    function up(ballup){
             mun=document.form2.item(ballup).value
             mun=parseFloat(mun)+0.25
             document.form2.item(ballup).value=mun
    }function down(balldown){
             mun=document.form2.item(balldown).value
             mun -= 0.25
             document.form2.item(balldown).value=mun
    }

    是不是因为你取了两个同名函数呢？
    将onclick="up　"　改为onclick="javascript:up　"
    试试
