Acknowledgements

Question 01: PHP array values with Javascript

Questions have come up in the Javascript forum a number of times recently regarding dynamically generated form fields where that names contain the [] characters like:

text name=myField[]>

They want to be able to address the fields via Javascript but it has trouble with the [] in the field names.

Is there a workaround so that these names could be rendered Javascript friendly without impairing the function on the PHP side?

A: Use the attribute id.

If you have a form field formatted as:

text name=thefield[0] id=thefield_0...>

You can use the id value in your object references in JavaScript:

document. ... .thefield_0.value

Question 02: Print Array - Columned HTML
