Using php variable in javascript -

-

this question has answer here:

i know doing totally wrong , haven't got idea how this.. have javascript function , trying use php declare array teams if round equals 1. teams , round come parameters in function teamelement()

  function teamelement(round, team, isready) {    <?php if(round == 1)  $round2_array[] = team) ?>    document.write('<p>round: ' + round + '<br>team ' + team.name + '<br> ready ' + isready);

...

anyone can please?

many thanks.

taking @ code, part:

function teamelement(round, team, isready) {   <?php if(round == 1)  $round2_array[] = team) ?>

i see lack of basic knowledge: javascript client side scripting language, while php server side scripting language. php , javascript executed in 2 different moments (generally php first , javascript (without using ajax)). therefore cannot share variables that easily.

there ways, though, connect 2 of them:

to pass php variable javascript script use string interpolation or templating features of php:

var x = <?php echo $x; ?>;

just notice that considered very bad practice , should use ajax here well.

to pass javascript variable php script can use ajax (asynchronous javascript , xml), execute php script "in background", after page loaded. in regard suggest take @ nice jquery library provides helpful set of functions task.
