Add Php Variables In Javascript

[newphpcoder]

Hi!I used javascript for my autocalculate and it works and now my problem is how can I SUM the total from autocalculate and the Data from other textbox.here is my code:

function autocalearn(oText){if (isNaN(oText.value)) //filter input{alert('Numbers only!');oText.value = '';}var field, val, oForm = oText.form, TotEarn = a = 0;for (a; a < arguments.length; ++a) //loop through text elements{field = arguments[a];val = parseFloat(field.value); //get valueif (!isNaN(val)) //number?{TotEarn += val; //accumulate}}oForm.TotEarn.value = TotEarn.toFixed(2); //out}</script>

The scenario is I have a Amount textbox and it has a value from database. And I have textboxes which is autocalculate and the total of that is display in total earn and now i want that the total earn and total amount will SUm and display in total earn..

<input name= "Amount" class = "LFieldTot" type="text" maxlength="12" tabindex="0" size="12" value="{$Amount}" readonly="readonly"/>

Thank you...I tried to put {Amount} in Total Earn Values but when I insert data in the earnings textbox the data was the calculate from the textboxes, it did not sum the Amount.

You can print a PHP variable right into your script.

var amount = <?php echo $Amount; ?>

Or if your script is using data from a form, access the form element:

var amount = document.getElementById("amount").value; <input type="text" id="amount">
