string length between Javascript and ASP

[joecool2005]

Hi all,When I execute this,<% sub check(temp) dim varASP varASP="abc" Response.Write(len(temp)&" "&len(varASP)) end sub%><script> var varJS="abc" document.write('<%call check("'&varJS&'")%>')</script> Why the length of "temp" and "varASP" are different?Thx for your helpJoe

what are the 2 lengths?have you tried this???

 Response.Write(len(Trim(temp))&" "&len(Trim(varASP)))

[joecool2005]

the length for "temp" is 9 and "varASP" is 3Also I tried with thisResponse.Write(len(Trim(temp))&" "&len(Trim(varASP)))same resultThx

Chances are the javascript variable is equal to 'undefined'When javascript has a problem setting the value of a variable it will set it to 'undefined'.Try changing this

 document.write('<%call check("'&varJS&'")%>')

to

 document.write('<%call check("' + varJS + '")%>')

Also did that way before and same result. But I noticed something strange.When you do both cases you will get different resultdocument.write('<%call check("'+varJS+'")%>')"temp" is 9 and "varASP" is 3document.write('<%call check("' + varJS + '")%>')"temp" is 13 and "varASP" is 3??????Both of them are used withResponse.Write(len(Trim(temp))&" "&len(Trim(varASP)))

That is odd. I am not sure what to suggest

[aspnetguy]

Give this a try

document.write('<' + '%call check("' + varJS + '")%' + '>')

It may be trying to execute the ASP call at this line, it is a long shot, but might work.

I tried to use your code like this<%sub check(temp)dim varASPvarASP="abc"Response.Write(len(Trim(temp))&" "&len(Trim(varASP)))end sub%><script>var varJS="abc"document.write('<' + '%call check("' + varJS + '")%' + '>')</script> And nothing was displayed
