js中for循环的问题
今天过来加班，运行了一下以前写的代码，竟然有问题，出错的地方是由于一段js代码引起的：
1
string scriptA = @"
2 <script>
3 var s ;
4 var sNun ;
5 var controlNum ;
6 var chkother= document.getElementsByTagName('input');
7 for (var i=0;i<chkother.length;i++)
8 {
9 if( chkother[i].type=='submit')
10 {
11 if(chkother[i].id.indexOf('btnSubmit')>-1)
12 {
13
14 s = chkother[i].id.split('_');
15 controlNum = s[s.length-1] ;
16 break ;
17 }
18 }
19 } ";
20 if( ViewState["PersonType"].ToString() != "" )
21
{
22
scriptA += @" var controlUserId = 'userName_'+s[s.length-1]+'_Value1' ;
23 var userIdValue = document.all['AppOpinion_list1_'+controlUserId].value ;
24 document.all.AppOpinion_list1_hiddMan.value = userIdValue; ";
25
}
26
27 scriptA += @" var controlRaesonId = 'txtOPinion_'+s[s.length-1];
28 var reasonValue = document.all['AppOpinion_list1_'+controlRaesonId].value ;
29 document.all.AppOpinion_list1_hiddoValue.value = reasonValue;
30
31 var j =0;
32 for (var i=0;i<chkother.length;i++)
33 {
34 if(chkother[i].id.indexOf('AppOpinion_list1_radiobtnResule_'+s[s.length-1])>-1)
35 {
36 j++;
37 if( chkother[i].checked )
38 {
39 sNun = j ;
40 }
41 }
42 }
43 document.all.AppOpinion_list1_hiddResult.value = sNun;
44 document.all.AppOpinion_list1_btnInsertFlow.click();
45 </script>";
46 Page.RegisterStartupScript("EA",scriptA);
string scriptA = @"2
<script>3
var s ;4
var sNun ;5
var controlNum ;6
var chkother= document.getElementsByTagName('input');7
for (var i=0;i<chkother.length;i++)8
{9
if( chkother[i].type=='submit')10
{11
if(chkother[i].id.indexOf('btnSubmit')>-1)12
{13
14
s = chkother[i].id.split('_'); 15
controlNum = s[s.length-1] ;16
break ;17
}18
}19
} ";20
if( ViewState["PersonType"].ToString() != "" )21
{
22
scriptA += @" var controlUserId = 'userName_'+s[s.length-1]+'_Value1' ;23
var userIdValue = document.all['AppOpinion_list1_'+controlUserId].value ;24
document.all.AppOpinion_list1_hiddMan.value = userIdValue; ";25
}26
27
scriptA += @" var controlRaesonId = 'txtOPinion_'+s[s.length-1]; 28
var reasonValue = document.all['AppOpinion_list1_'+controlRaesonId].value ;29
document.all.AppOpinion_list1_hiddoValue.value = reasonValue;30
31
var j =0;32
for (var i=0;i<chkother.length;i++)33
{34
if(chkother[i].id.indexOf('AppOpinion_list1_radiobtnResule_'+s[s.length-1])>-1)35
{36
j++;37
if( chkother[i].checked )38
{39
sNun = j ;40
}41
}42
}43
document.all.AppOpinion_list1_hiddResult.value = sNun;44
document.all.AppOpinion_list1_btnInsertFlow.click();45
</script>";46
Page.RegisterStartupScript("EA",scriptA);在for循环中没有增加break的时候，s[s.length-1]的值在先后的调用中会不同，这点就比较郁闷
，增加break语句跳出循环，就不会存在该问题，值的改变也只是在if语句中，而且确认一个数据符合if语句，虽然问题解决了，但是还不知道原因，以后在找找原因了，mark。。。
