javascript加减乘除的简洁实例_

1、javascript加减乘除的简洁实例_ 下面我就为大家带来一篇javascript加减乘除的简洁实例。我觉得挺不错的，现在就分享给大家，也给大家做个参考。 javascript加减乘除的简洁实例 html head meta http-equiv=Content-Type content=text/html;charset=utf-8 / /head script language=javascript type=text/javascript /除法函数 function accDiv(arg1,arg2) var t1 = 0, t2 = 0, r1, r2, n; try t1 = a

2、rg1.toString().split(.)1.length; catch(e) t1 = 0; try t2 = arg2.toString().split(.)1.length; catch(e) t2 = 0; with(Math) r1 = Number(arg1.toString().replace(.,); r2 = Number(arg2.toString().replace(.,); n = Math.max(t1,t2); return (r1/r2)*pow(10, t2-t1); /乘法函数 function accMul(arg1,arg2) var t1 = 0,

3、t2 = 0, r1, r2; try t1 = arg1.toString().split(.)1.length; catch(e) t1 = 0; try t2 = arg2.toString().split(.)1.length; catch(e) t2 = 0; with(Math) r1 = Number(arg1.toString().replace(.,); r2 = Number(arg2.toString().replace(.,); return (r1*r2)/pow(10, t2+t1); /加法函数 function accAdd(arg1,arg2) var t1

5、lit(.)1.length; catch(e) t1 = 0; try t2 = arg2.toString().split(.)1.length; catch(e) t2 = 0; with(Math) /动态掌握精度长度 n = Math.max(t1,t2); m = Math.pow(10, n); /return (arg1 * m - arg2 * m) / m; return (arg1 * m - arg2 * m) / m).toFixed(n); /给String类型增加一个div方法，调用起来更加便利。 Stotype.div = function (

6、arg) return accDiv(this, arg); /给String类型增加一个mul方法，调用起来更加便利。 Stotype.mul = function (arg) return accMul(arg,this); /给String类型增加一个add方法，调用起来更加便利。 Stotype.add = function (arg) return accAdd(arg,this); /给String类型增加一个subtr方法，调用起来更加便利。 Stotype.subtr = function (arg) return accS

7、ubtr(this, arg); function cal() var arg1 = document.Form1.TextBox1.value; var arg2 = document.Form1.TextBox2.value; /document.Form1.TextBox5.value = accDiv(arg1, arg2); /document.Form1.TextBox6.value = accMul(arg1, arg2); /document.Form1.TextBox7.value = accAdd(arg1, arg2); /document.Form1.TextBox8.

8、value = accSubtr(arg1, arg2); document.Form1.TextBox5.value = arg1.div(arg2); document.Form1.TextBox6.value = arg1.mul(arg2); document.Form1.TextBox7.value = arg1.add(arg2); document.Form1.TextBox8.value = arg1.subtr(arg2); /script body form id=Form1 name=Form1 method=post runat=server div style=bor
