JS校验价格和金额的方法

直接上代码

function isPriceNumber(_keyword){if(_keyword == "0" || _keyword == "0." || _keyword == "0.0" || _keyword == "0.00"){_keyword = "0"; return true;}else{var index = _keyword.indexOf("0");var length = _keyword.length;if(index == 0 && length>1){/*0开头的数字串*/var reg = /^[0]{1}[.]{1}[0-9]{1,2}$/;if(!reg.test(_keyword)){return false;}else{return true;}}else{/*非0开头的数字*/var reg = /^[1-9]{1}[0-9]{0,10}[.]{0,1}[0-9]{0,2}$/;if(!reg.test(_keyword)){return false;}else{return true;}}return false;}}
