Javascript参数传递不起作用

Question

The code dynamically creates a listview which works but i want to make it so when a listview item is clicked it sends the a url paramater to another method. When i set a paramater it doesnt alert the paramater, but when i give no parameter it works.

var output = 
"<li onclick='openURL()'><h3> Module Code: " + 
results.rows.item(i).module 
+ "</h3>Room: " 
+ results.rows.item(i).room +
"</li>";

The above works - No parameter in openURL();

var output = 
    "<li onclick='openURL('" + results.rows.item(i).url + "')'><h3> Module Code: " + 
    results.rows.item(i).module 
    + "</h3>Room: " 
    + results.rows.item(i).room +
    "</li>";

The above doesnt work - I have done alert(results.rows.item(i).url) and it has a value.

function openURL(url) {
    alert("opening url " + url);
} 

Could someone explain what i'm doing wrong, i've been trying to solve the problem for hours.

Cheers!

You are using single quotes to open the HTML attribute, you can't use it as JavaScript String because you'll be closing the HTML attribute, use double quotes:

var output = 
    "<li onclick='openURL(\"" + results.rows.item(i).url + "\")'><h3> Module Code: " + 
    results.rows.item(i).module 
    + "</h3>Room: " 
    + results.rows.item(i).room +
    "</li>";
