jQuery 检测 Bootstrap 3 状态 [英] jQuery detect Bootstrap 3 state

问题描述

在 Bootstrap 3 中，有 4 个状态；超小型设备、小型设备、中型设备和大型设备.我如何知道网站当前处于使用 jQuery 的哪个状态?这样我就可以像在超小型设备中那样做一些处理，然后运行这个函数.

谢谢.

解决方案

我对 this 对于引导程序 3，试试这个"

function findBootstrapEnvironment() {var envs = ["ExtraSmall", "Small", "Medium", "Large"];var envValues = ["xs", "sm", "md", "lg"];var $el = $('
');$el.appendTo($('body'));for (var i = envValues.length - 1; i >= 0; i--) {var envVal = envValues[i];$el.addClass('hidden-'+envVal);如果 ($el.is(':hidden')) {$el.remove();返回环境[i]}};}

In Bootstrap 3, there are 4 states; extra small devices, small devices, medium devices, and large devices. How can I know the website is currently at which state with jQuery? So that I can do some processing like when it is in extra small devices, then run this function.

Thanks.

解决方案

I made some changes to this for bootstrap 3, try this"

function findBootstrapEnvironment() {
    var envs = ["ExtraSmall", "Small", "Medium", "Large"];
    var envValues = ["xs", "sm", "md", "lg"];

    var $el = $('<div>');
    $el.appendTo($('body'));

    for (var i = envValues.length - 1; i >= 0; i--) {
        var envVal = envValues[i];

        $el.addClass('hidden-'+envVal);
        if ($el.is(':hidden')) {
            $el.remove();
            return envs[i]
        }
    };
}
