Setimeout providing Uncaught ReferenceError: function undefined
Can someone tell me why this is giving an error?
I have moved the code in functions to allow me to delay it so that it is not so sensitive (annoyed)
Uncaught ReferenceError: hideleftnav is not defined
Unprepared ReferenceError: showleftnav is not defined
function showleftnav()
{
$(".leftnavdiv").css('width','500px');
$("body").css('padding-left','510px');
//get measurements of window
var myWidth = 0, myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
myWidth = window.innerWidth;
myHeight = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
myWidth = document.documentElement.clientWidth;
myHeight = document.documentElement.clientHeight;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
//IE 4 compatible
myWidth = document.body.clientWidth;
myHeight = document.body.clientHeight;
}
$('#maindiv').width(myWidth - 540);
}
function hideleftnav()
{
$(".leftnavdiv").width(10);
$("body").css('padding-left','20px');
//get measurements of window
var myWidth = 0, myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
myWidth = window.innerWidth;
myHeight = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
myWidth = document.documentElement.clientWidth;
myHeight = document.documentElement.clientHeight;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
//IE 4 compatible
myWidth = document.body.clientWidth;
myHeight = document.body.clientHeight;
}
$('#maindiv').width(myWidth - 50);
}
$(".leftnavdiv").live({ //code for autohide
mouseenter:
function () {
setTimeout("showleftnav()", 5000);
},
mouseleave:
function () {
setTimeout("hideleftnav()", 5000);
}
});

It looks like you found one problem using setTimeout
with a string as the first argument. Here's an example to illustrate the same problem:
(function() {
function test() {
console.log('test');
}
setTimeout('test()', 500); // ReferenceError: test is not defined
setTimeout(test, 500); // "test"
setTimeout(function() { // "test"
test();
}), 500);
})();

Using a string causes your code to be evaluated using context window
. But since your code is in a callback function, it is test
not available from window
; it is private and limited to the scope of the anonymous function only.
Using a function-only reference test
fixes this problem because you are referring directly to a function without using eval
.
