Detect a window width change but not a height change

Question

I\'m using the .resize() function to detect window re-size events, but this detects both height and width changes.

Is there any way to detect ju

The link provided by @nachtigall is broken, so I found this other with the same library, which helped me to solve my issue: resize-dimension.js

Example of solution is as follow: Import library:

Create script:

The function ForResize() gets fired when the browser is resized, though in this case, IE handles it better than the other browsers, however, in my case, it worked fine for mobile devices, which where firing the events when scrolling the page, which depending on the mobile browser, it can hide the address bar, which affects the browser's size. Implementing that library helped!

I used the counter/timer provided here and modified it to my needs. The following are the critical scripts that I had to create:

In case that the library's link gets broken again, here is the code from the same source (resize-dimension.js):

(function (root, factory) {
  var moduleName = 'ResizeDimension';
  if (typeof define === 'function' && define.amd) {
    define(['jquery'], function ($) {
        return (root[moduleName] = factory($));
    });
  } else {
    root[moduleName] = factory(root.$);
  }
}(this, function ($) {

  var $window = $(window);

  var ResizeDimension = function ($el, dimension, handler, options) {

    if (! (this instanceof ResizeDimension)) {
      return new ResizeDimension($el, dimension, handler, options);
    }

    this.$el = $el;

    this.init(dimension, handler, options);

    return this;
  };

  /**
   * Stub - overridden on #init()
   */
  ResizeDimension.prototype.onResize = function () {};

  ResizeDimension.bound = {};

  ResizeDimension.bind = function (dimension, options) {
    if (ResizeDimension.bound[dimension]) return;
    ResizeDimension.bound[dimension] = true;
    $window.resizeDimension(dimension, function () {
      $window.trigger('resize-' + dimension);
    }, options);
  };

  ResizeDimension.prototype.init = function (dimension, handler, options) {

    if (typeof dimension === 'object') {
      options = dimension;
      dimension = options.dimension;
      handler = options.handler;
    }

    options = $.extend({}, options);
    options.dimension = dimension;
    options.handler = handler;

    this.options = options;

    if ($.isFunction(options.changed)) {
      this.changed = options.changed;
    }

    this.dimension = this.normalize(options.dimension);
    this.handler = options.handler;
    this.previousValue = this.value();

    var proxied = $.proxy(this.handle, this);
    if (options.throttler) {
      this.onResize = options.throttler(proxied);
    }
    else {
      this.onResize = proxied;
    }
  };

  ResizeDimension.prototype.normalize = function (dimension) {
    return dimension;
  };
  ResizeDimension.prototype.changed = function (previous, current) {
    return previous !== current;
  };

  ResizeDimension.prototype.value = function (e) {
    return this.$el[this.dimension]();
  };

  ResizeDimension.prototype.handle = function (e) {
    var currentValue = this.value();
    if (this.changed(this.previousValue, currentValue)) {
      this.previousValue = currentValue;
      return this.handler.call(this.$el, e);
    }
  };

  var $resizeDimension = function () {
    var args = Array.prototype.slice.call(arguments);
    return this.each( function() {
      var $el = $(this);
      args = [$el].concat(args);
      var instance = ResizeDimension.apply(null, args);
      $el.on('resize', $.proxy(instance.onResize, instance));
    });
  };

  $.fn.resizeDimension = $resizeDimension;

  return ResizeDimension;
