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 = 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(".",""); n = Math.max(t1,t2); return (r1/r2)*pow(10, t2-t1); /乘法函数 function accMul(arg1,arg2) var t1 = 0, 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 = 0, t2 = 0, m; try t1 = arg1.toString().split(".")1.length; catch(e) t1 = 0; try t2 = arg2.toString().split(".")1.length; catch(e) t2 = 0; with(Math) m=Math.pow(10,Math.max(t1,t2); return (arg1 * m + arg2 * m) / m; /减法函数 function accSubtr(arg1,arg2) var t1 = 0, t2 = 0, m, n; try t1 = arg1.toString().split(".")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。 String.prototype.div = function (arg) return accDiv(this, arg); /给String类型增加一个mul方法，调用起来更加便利。 String.prototype.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。 String.prototype.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。 String.prototype.subtr = function (arg) return accSubtr(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.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="border:solid 1px #000000; width:600px;" div style="float:left; width:30%;"input id="TextBox1" type="text" value="0" name="TextBox1" /div div style="float:left; width:30%;"input id="TextBox2" value="0" type="text" name="TextBox2" /div div style="float:left; width:30%;" divaccDiv：input id="TextBox5" type="text" name="TextBox5" /div divaccMul：input id="TextBox6" type="text" name="TextBox6" /div divaccAdd：input id="TextBox7" type="text" name="TextBox7" /div divaccSubtr：input id="TextBox8" type="text" name="TextBox8" /div /div div style="float:right; width:10%;"input type="button" name="aa" value="cal" onclick="cal();" /div /div /form /body /html 以上这篇javascript加减乘除的简洁实例就是我分享给大家的全部内容了，盼望能给大家一个参考 .
