How do I make JavaScript to set these element values?
- by dmanexe
I have two fields that need to multiply each other and fill a 3rd form's value. Here's the HTML:
<input type="text" name="estimate[concrete][price]" value="" onBlur="calc_concreteprice(document.forms.mainform);" />
per SF <strong>times</strong>
<input type="text" name="estimate[concrete][sqft]" value="" onBlur="calc_concreteprice(document.forms.mainform);" /> SF
= <input type="text" name="estimate[concrete][quick_total]" value="" />
Here's my JavaScript:
function calc_concreteprice(mainform) {
var oprice;
var ototal;
oprice = ((mainform.estimate[concrete][sqft].value) * (mainform.estimate[concrete][price].value));
ototal = (oprice);
mainform.estimate[concrete][quick_total].value = ototal;
}
I want the first two forms to be multiplied together and output to the third. I think my problem may be within how I am referencing the input field names, with brackets (I'm taking results from this form as an array so I'm already used to working with the results as a multi-dimensional array).
Thanks for the help!
