一个js问题
window.onload=function() {var pro ="";
var payFee1="";
var num;
var userid = document.getElementsByName("paidfee/USERID")[0].value;
var sub = new HiddenSubmit("ACCT.bizBusiExpectPayFee.bizExpectPayFeeTaishouQuery");
sub.add("T_AR_USERINFO/USERID",userid);
sub.add("T_BL_COMMERADVANCERECORD/YRMONTH","");
if(sub.submit()){
num = sub.getProperty("list[@type='modify']/@rowNum");
for(var i=0;i <num;i++){
pro += sub.getProperty("list[@type='modify']/modify[@rowNum="+i+"]/yrmonth")+",";
var payFee = sub.getProperty("list[@type='modify']/modify[@rowNum="+i+"]/chrgsum");
payFee1 += parseFloat(payFee).toFixed(2);
}
if(num>0){
alert("该工商户"+pro+"预付费未缴，未缴总金额为￥"+payFee1+"");
}
}
}
这个payFee 是个浮点型的，我想每次循环一次就把她相加起来，赋值给payFee1 ，现在的情况是payFee1 是个很长的字符串，数字并没有相加，有什么办法把他加起来没有捏？
补充：window.onload=function() {
var pro ="";
var payFee1=parseFloat(0.00);
var num;
var userid = document.getElementsByName("paidfee/USERID")[0].value;
var sub = new HiddenSubmit("ACCT.bizBusiExpectPayFee.bizExpectPayFeeTaishouQuery");
sub.add("T_AR_USERINFO/USERID",userid);
sub.add("T_BL_COMMERADVANCERECORD/YRMONTH","");
if(sub.submit()){
num = sub.getProperty("list[@type='modify']/@rowNum");
for(var i=0;i<num;i++){
pro += sub.getProperty("list[@type='modify']/modify[@rowNum="+i+"]/yrmonth")+",";
var payFee = sub.getProperty("list[@type='modify']/modify[@rowNum="+i+"]/chrgsum");
alert(payFee);
payFee1 = payFee1 + parseFloat(payFee).toFixed(2);
alert(payFee1);
}
if(num>0){
alert("该工商户"+pro+"预付费未缴，未缴总金额为￥"+payFee1+"");
}
}
}
