很多时候发现有时候js会提示自带函数不能使用，所以自己找了很多资料实现了个
html
<input type="text" class="input_text input_number" name="mgsy_dbnfjlr" value="" onblur="this.value=fouces_qfh(this.value)" />
js函数
/*** 自动补充百分比符号* @param obj* @returns {String}*/function fouces_bfh(obj) {var o = obj.replace(',', '') + "";if (o.indexOf("%") > -1) {o = o.replace('%', '') + "";//o = Number(o)/100;}else{o = o*100;}o = format1(o);if (o.indexOf(".") <= -1) {return o += ".00%";}if (o.substr(o.length - 1, 1) == ".") {return o += ".00%";}if (o.substr(o.length - 2, 1) == ".") {return o += "0%";}return o + "%";}
/*** 千分符格式化* @param num* @returns*/function format1 (num) {if( num == null || num == undefined || num == "" ){return "";}if( isNaN(num)) return num;//alert(num);//return (parseFloat(num).toFixed(2) + '').replace(/\d{1,3}(?=(\d{3})+(\.\d*)?$)/g, '$&,');return (toFixed(num,2) + '').replace(/\d{1,3}(?=(\d{3})+(\.\d*)?$)/g, '$&,');}function toFixed(number, precision) {var b = 1;if (isNaN(number)) return number;if (number < 0) b = -1;var multiplier = Math.pow(10, precision);return Math.round(Math.abs(number) * multiplier) / multiplier * b;}
另
/*** 千分符格式化* @param num* @returns*/function format1 (num) {if( num == null || num == undefined || num == "" ){return "";}if( isNaN(num)) return num;//alert(num);return (parseFloat(num).toFixed(2) + '').replace(/\d{1,3}(?=(\d{3})+(\.\d*)?$)/g, '$&,');//return (toFixed(num,2) + '').replace(/\d{1,3}(?=(\d{3})+(\.\d*)?$)/g, '$&,');}
