将数据传递到send.php-选择选项文本和值

Question

Basically i am trying to debug this: Ihave a HTML form and a send.php from which i extract data like

 $locridicare= addslashes($_GET['liv']); 
 $locreturnare=addslashes($_GET['ret']); 
 $codlocridicare=addslashes($_GET['locridicare']); 
 $codlocreturnare=addslashes($_GET['locreturnare']);

The codlocridicare should get the VALUE and the locridicare should get the TEXT from the SELECT option called locridicare.

Same for codlocreturnare and locreturnare, from the other select.

The form i run:

<script>
function changelivrare (objDropDown)
{
document.getElementById("liv").value = objDropDown.value; 
}


function changereturnare (objDropDown)
{
document.getElementById("ret").value = objDropDown.value; 
}
</script>

and then the in form

<select name="locridicare" id="locridicare" onchange="changelivrare(this)">
<option value=""> --- Selectaţi --- </option>
<option value="3231">Aeroport Otopeni - Bucuresti</option>
</select>
<input type="hidden" name="liv" id="liv" />

<select name="locreturnare" id="locreturnare" onchange="changereturnare(this)" >
<option value=""> --- Selectaţi --- </option>
<option value="3231">Aeroport Otopeni - Bucuresti</option>
</select>
<input type="hidden" name="ret" id="ret" />

Answer 1

To get the selected option's text, use:

function changelivrare(objDropDown) {
    document.getElementById("liv").value = objDropDown.options[objDropDown.selectedIndex].innerHTML;
}

objDropDown.value is the value of the selected option, not its text. objDropDown.options is a collection of the options, and objDropDown.selectedIndex is the position of the selected option.

I also suggest you combine the two function into one:

function textToHiddenInput(objDropDown, inputID) {
    document.getElementById(inputID).value = objDropDown.options[objDropDown.selectedIndex].innerHTML;
}

Then you change the HTML to:

<select name="locridicare" id="locridicare" onchange="textToHiddenInput(this, 'liv')">
...
<select name="locreturnare" id="locreturnare" onchange="textToHiddenInput(this, 'ret')" >
