    copied!<p>Using Jinja2 GAE Datastore.<br> In my template html javascript script section - I want to call a function triggered by onclick and pass 2 arguments. The second argument is a GAE key value. It seems the key is retrieved but then when it is passed as an argument - I get an uncaught reference error undefined - almost seems like it views it as an undefined variable?</p> <pre><code>html_output += "&lt;input class='filter_submit first_level' name='first_input' type='button' onclick='pass_hidden(1,{{one.key()}})' value='{{one.name1}}'&gt;&lt;/input&gt;&lt;br /&gt;"; </code></pre> <p>HERE IS THE FUNCTION CALLED BY THE ONCLICK...</p> <pre><code>function pass_hidden(num,key_val) { alert('in pass_hidden function'); var add_html; if (num=='1') { add_html += "&lt;input type='hidden' value='key_val' name='second_input'&gt;&lt;/input&gt;&lt;input type='hidden' value='1' name='heading_number'&gt;&lt;/input&gt;"; } else if (num=='2') { add_html +="&lt;input type='hidden' value='key_val' name='second_input'&gt;&lt;/input&gt;&lt;input type='hidden' value='2' name='heading_number'&gt;&lt;/input&gt;"; } else if (num=='3') { add_html +="&lt;input type='hidden' value='key_val' name='second_input'&gt;&lt;/input&gt;&lt;input type='hidden' value='3' name='heading_number'&gt;&lt;/input&gt;"; } add_html +="&lt;input type='hidden' name='heading_type' value='subject'&gt;&lt;/input&gt;"; /*$("hidden_inputs").append(add_html); */ document.getElementById("hidden_inputs").innerHTML = add_html; document.userchoices.submit(); } </code></pre>
