Question

Send Value through to dynamic form

Asked by: js23847

Hello -

If you go here: http://www.find-appraisers.com/appraisers/county/?State=IL&County=Bond&B2=Find+Appraisers%21 and select 'Appraiser Request', you'll notice the 'State' box is pre-populated based on the previous page -- the county box is dependent on the state and dynamically changes.  My question is - how do I push the county value through to the form so its pre-populated like the state box?

If you could be very specific and provide the code that will accomplish this I would appreciate it - I know very little about java - thanks!!

Use my version of this function:

function populateCountry(inForm,selected) {
  if (selected == "") {
    return;
  }
  var selectedArray = eval(selected + "Array");
  var opt = inForm.County.options;
  opt.length = 0;

  for (var i=0; i < selectedArray.length; i++) {
    var selVal = selectedArray[i].match(/'([^\']+)'/)[1];
    var selOpt = false;
    if(location.search.indexOf("County="+selVal)>0) selOpt = true;
    opt[opt.length] = new Option(selVal, selVal, selOpt, selOpt);
  }
  if (inForm.State.options[0].value == '') {
    inForm.State.options[0]= null;
    if (navigator.appName == 'Netscape') {
      if (parseInt(navigator.appVersion) < 4 ||
          navigator.platform == 'Win32' ||
          navigator.platform == 'Win16') {
        window.history.go(0);
      }
    }
  }
}


and change your link to this:
<a style="color: #3333cc; font-weight:700" href="http://www.find-appraisers.com/appraisers/appraiser_request/?State=IL&County=Bond">
                        Appraiser Request</a>

That breaks the form.  Once I made the change, the county will no
longer populate even after switching the state.

 

by: ZvonkoPosted on 2004-12-05 at 23:17:38ID: 12751745

Change the functions to this:

function populateCountry(theSel) {
  if (theSel.value == "") {
    return;
  }
  var inForm = theSel.form;
  var selVal = theSel.value
  var ctyVal = location.search.split("County=");
  if(ctyVal.length>1){
    ctyVal = (ctyVal[1]+"&").split("&")[0];
  }
  cVal = document.cookie.split("County=");
  if(cVal.length>1){
    ctyVal = (cVal[1]+";").split(";")[0]
  }

  var selectedArray = eval(selVal + "Array");
  var opt = inForm.County.options;
  opt.length = 0;

  for (var i=0; i < selectedArray.length; i++) {
    var optVal = selectedArray[i].match(/'([^\']+)'/)[1];
    var selOpt = false;
    if(location.search.indexOf("County="+optVal)>0) selOpt = true;
    opt[opt.length] = new Option(optVal, optVal, selOpt, selOpt);
  }
}

function populateUSCounty(theSel) {
  document.cookie = "County="+theSel.value;
}

The body tag to this:
<BODY text="#000000" bgColor="#ffffff" link="#1A52A4" vlink="#1A52A4" alink="#1954A3"
onload="populateCountry(document.globe.State)" >

And the select tags to this:
<select name="State" onchange="populateCountry(this)">

And this:
<select name="County" onchange="populateUSCounty(this)">
