Are you sure that this assignment is correct, and you did not intend to make a comparison?

Even if this assignment is intended here, we recommend to make this explicit in order to make your code more readable and your intention clear:

1. Assignment in 

var x;
if (x = 0) { // Very likely a bug.
    var b = 1;
}

// Instead

var x;
if (x === 0) {
    var b = 1;
}

2. Assignment in 

functon setHeight(node, height) {
    do {
        node.height = height;
    } while (node = node.parentNode);
}

// Instead you could use

function setHeight(node, height) {
    do {
        node.height = height;
    } while ((node = node.parentNode) !== null);
}

3. Uninitialized loop variable

var i = 0, sum;
for (i < 10; i += 1) {
    sum += i;
}

// Instead

var i = 0, sum;
for (i = 0; i < 10; i += 1) {
    sum += i;
}

Bug introduced by
The variable myurl seems to be used out of scope.

This error can usually be fixed by declaring the variable in the scope where it is used:

function someFunction() {
    (function() {
        var i = 0;
    })();

    // i is not defined.
    alert(i);
}

// This can be fixed by moving the var statement to the outer scope.

function someFunction() {
    var i;
    (function() {
        i = 1;
    })();

    alert(i);
};
