Where is the problem?
Posted: Mon Dec 05, 2011 1:58 am
This code does not run in line 7, why?
The first combobox (C0) item selected and second combobox (C1) filled too, but nothing in second combobox did not select and so the third (C2) and the forth (C3) combobox did not fill.
The function change fill each combo box from what selected in previous combobx:
Code: Select all
function selectcity()
{
$('select.city').val('<?php echo($_city); ?>');
$('select.c0').val('<?php echo($_data_ar[0]); ?>');
c=document.forms["testForm"].elements["combo0"];
change(c);
$('select.c1').val('<?php echo($_data_ar[1]); ?>');
c=document.forms["testForm"].elements["combo1"];
change(c);
$('select.c2').val('<?php echo($_data_ar[2]); ?>');
c=document.forms["testForm"].elements["combo2"];
change(c);
$('select.c3').val('<?php echo($_data_ar[3]); ?>');
}
The function change fill each combo box from what selected in previous combobx:
Code: Select all
function change(currentbox) {
numb = currentbox.id.split("_");
currentbox = numb[1];
i=parseInt(currentbox)+1
// I empty all combo boxes following the current one
while ((eval("typeof(document.getElementById(\"combo_"+i+"\"))!='undefined'")) &&
(document.getElementById("combo_"+i)!=null)) {
son = document.getElementById("combo_"+i);
// I empty all options except the first one (it isn't allowed)
for (m=son.options.length-1;m>0;m--) son.options[m]=null;
// I reset the first option
son.options[0]=new Option(displaywhenempty,valuewhenempty)
i=i+1
}
// now I create the string with the "base" name ("stringa"), ie. "data_1_0"
// to which I'll add _0,_1,_2,_3 etc to obtain the name of the combo box to fill
stringa='data'
i=0
while ((eval("typeof(document.getElementById(\"combo_"+i+"\"))!='undefined'")) &&
(document.getElementById("combo_"+i)!=null)) {
eval("stringa=stringa+'_'+document.getElementById(\"combo_"+i+"\").selectedIndex")
if (i==currentbox) break;
i=i+1
}

following=parseInt(currentbox)+1
if ((eval("typeof(document.getElementById(\"combo_"+following+"\"))!='undefined'")) &&
(document.getElementById("combo_"+following)!=null)) {
son = document.getElementById("combo_"+following);
stringa=stringa+"_"
i=0
while ((eval("typeof("+stringa+i+")!='undefined'")) || (i==0)) {
// if there are no options, I empty the first option of the "son" combo
// otherwise I put "-select-" in it
if ((i==0) && eval("typeof("+stringa+"0)=='undefined'"))
if (eval("typeof("+stringa+"1)=='undefined'"))

i=i+1
}
//son.focus()
i=1
combostatus=''
cstatus=stringa.split("_")
while (cstatus[i]!=null) {
combostatus=combostatus+cstatus[i]

}
return combostatus;
}
