Hi everyone,

 

I am trying to read some values from the page calling this function and pass this values from the input fields to the ajax function. Please its giving me erro's i need some urgent help please.

 

 

Here is the code:

 

 

<input type=hidden value="1" id='field_1text>
<input type=text id='field_2text' onclick="javascript: checkmake('field_1text','field_2text')">


function checkmake(check_div1, check_div2) {

if(check_div1 || check_div2)
{
var check_value1 = document.getElementById(check_div1).value;
var check_value2 = document.getElementById(check_div2).value;

MyAjaxRequest("displaymodels","requestmodel.php?amake=$check_value1&amodel=$check_value2");
}
else
{
var check_value1 = '';
var check_Value2 = '';
alert("Please select the make first");
}

}

 

This showing me $check_value1 variable in my php file it's not passing the value of check_value1 or check_value2, please help.

I think I see the problem

 

check the following line

MyAjaxRequest("displaymodels","requestmodel.php?amake=$check_value1&amodel=$check_value2");

if I am right $check_value1 $check_value2 are your php variables but your passing it as if they are javascript variables

 

you need to convert this variable to javascript variable first try this:

//pass php values to javascript
var checkValue1="<?php echo($check_value1);?>";
var checkValue2="<?php echo($check_value2);?>";
//ajax request correction
MyAjaxRequest("displaymodels","requestmodel.php?amake="+checkValue1+"&amodel="+checkValue1);

 

oh one thing else i see you have both $check_value1 and check_value1 looks a bit confusing

and in the following line

var check_value1 = document.getElementById(check_div1).value;

 

are you trying to get a value out of a div tag? Don't think div tags are suppose to have the "value" attribute they do have innerHTML so that would look like

var check_value1 = document.getElementById(check_div1).innerHTML;
