Count characters in anchor and resize it

I'm trying to build a script that counts the number of characters in an anchor tag inside a list item and, if the number of characters is higher than 18, makes the anchor tag narrower so that the text will break. Here's what I have so far, but it's not working. Help?

        $('nav li a').each(function() {
            var curr = this.text().length();
            if(c开发者_运维技巧urr >= 18){
                this.width(50);
            }
        });

Oh, and for bonus points: is there some way to make the text on the second line indent after the anchor shrinks?

try this instead:

    $('nav li a').each(function() {
        var curr = $(this).text().length;
        if(curr >= 18){
            $(this).width(50);
        }
    });

I notice you're missing a character from your nav selector - either a . or a #

For your second point about indenting the second line, try this:

#nav li a {
    display: block;
    margin-left: 15px;
    text-indent: -15px;    
}

You've got a few little glitches here.

• You have to do everything after the page loads, so something like $(document).ready(...) would be necessary.
• The each function doesn't work quite like you had it, it takes two parameters that you can then work with.
• And lastly, the anchor tag is an inline tag, so it has no width. For what you want to work you'd need to either style your a tags with display: block or display: inline-block, or just use a different container.

So this would work with the text directly in the list item for example:

$(document).ready(function(){
    $('li').each(function(index, listItem) {
        var curr = $(listItem).text().length;
        if(curr >= 18){
            $(listItem).width(50);
        }
    });
});

Just a shot in the dark:

You probably didn't set the anchor's display to block or inline-block.

Alternatively, you've got a particularly long word, which will not break automatically unless you add some <wbr>s. Quirksmode has a nice page about wordbreaks
