JS赋值问题
function addinput(c){
var sess0 = "q ";
var sess1 = "w ";
var sess2 = "e ";
for (var m=0;m <c;m++ )
{
document.getElementById( "strfile "+m+ " ").value=sess+m;
}
}
上面的C是外部传入的参数，
比如外面有3个input
现在传入参数 让 c=3
<input name= "strfile0 " type= "text " />
<input name= "strfile1 " type= "text " />
<input name= "strfile2 " type= "text " />
如何让JS给上面三个文本框赋值呢？
document.getElementById( "strfile "+m+ " ").value=sess+m;
这句是错的，希望高人能指点下
------解决方案--------------------
document.getElementById( "strfile "+m+ " ").value = eval( "sess "+m);
