I`m just using a If statement with the logical operator. I dont know why it is showing sytax error.

var divWidth = $("#columnwraper").width(); //getting the width of the div   
$("#right-button").click(function() {
    if (cursor != totalWidth && totalWidth !< divWidth) {
        $box2.animate({
            marginLeft : "-=300"
        }, "fast");

        cursor += 100;
    }
    // console.log(colwidth.width());
});

It`s showing that

[15:18:24.050] SyntaxError: missing ) after condition.

What am I doing wrong here?

• 2 What is !< operator? Why you don't use >= instead? – Petr R. Commented Jun 27, 2013 at 9:56
• 3 Note that != is one operator. It is not a bination of ! and ==. You cannot simply bine ! with other operators (i.e. !< is invalid). – Felix Kling Commented Jun 27, 2013 at 9:58

Put it this way:

if (cursor != totalWidth && !(totalWidth < divWidth))

!< is not an operator.

Error in totalWidth !< divWidth

Should be totalWidth < divWidth or totalWidth >= divWidth

Always put logical operators in inner brackets for operations like: (totalWidth < divWidth)

And !< is not an operator. You should use this:

 if ((cursor != totalWidth) && !(totalWidth < divWidth)) {... }
