Use JavaScript or jQuery to implement the position absolute styling

I am currently working on a website where the navigation is aligned to the right side.

However, I am facing an issue where the last menu item dropdown extends beyond the page because it is absolutely positioned to the left of its parent element.

I am actively seeking a solution to address this problem with my navigation menu.

jsfiddle -http://jsfiddle.net/ashconnolly/6gjVr/

I am unable to manually set a fixed left position using 'xx' because the width of the last menu item may vary depending on the text content within it. That's why I am using JavaScript to dynamically adjust the position.

I am close to finding a solution, but I need to figure out how to apply a variable absolute left position only on hover. If possible, a CSS-only solution would be ideal, but I haven't found one yet.

Any assistance or advice on how to overcome this issue would be greatly appreciated! :)

Edit: updated explanation.

Answer №1

After already determining the width of your previous menu item, why did you choose not to utilize it?

$(document).ready(function () {
var menuitemwidth = document.getElementById("last-menu-item").offsetWidth;
var menuitemdropdownwidth = document.getElementById("last-menu-item-drop-down").offsetWidth;
//alert(menuitemwidth);
var leftval = menuitemdropdownwidth - menuitemwidth;
//alert(leftval);
    $("#last-menu-item").mouseenter(function(){
        $("#last-menu-item-drop-down").css({'position':'absolute','left':'-'+leftval+'px','display':'block'});
    });
    $("#last-menu-item").mouseleave(function(){
        $("#last-menu-item-drop-down").css({'display':'none'});
    });

});

Answer №2

It is common knowledge that using a framework to "print" javascript values is not recommended, as it can quickly lead to an unmaintainable mess.

However, it is possible to separate the logic of an element from its presentation by formatting html elements in templates with a data-attribute like so:

<div id="example-element" data-position="center" data-value="50px">

Then, adjust the javascript accordingly:

// cache the element for quicker access
var example_elem = $("#example-element");

// set position and alignment
example_elem.css('position','relative').css(example_elem.data("position"), example_elem.data("value"));

// hide the element initially
example_elem.hide();

// show/hide the element as needed
// ...

You can also calculate offsets in javascript and only specify the position in your templates.

Having trouble styling with css 

$("#menu-item").mouseenter(function(){
var x=-(parseInt($("#menu-item-drop-down").css('width'))-parseInt($("#menu-item").css('width')));
 $("#menu-item-drop-down").css('position','absolute').css('left',x);
 $("#menu-item-drop-down").show();
});
$("#menu-item").mouseleave(function(){
   $("#menu-item-drop-down").hide();
});
