如何使用JavaScript和CSS Grid根据屏幕/视口大小使RadWindow响应

我一直在寻找使Telerik RadWindow响应式工作的解决方案。需要响应的两件事是RadWindow中的内容和RadWindow本身。

问题:

每个Telerik: RadWindow不支持响应大小更改,并且它不能根据视口自动更改大小,因为无法严格定义这种情况下的行为

解决方案: (RadWindow内部的内容需要响应,RadWindow本身也需要响应)

RadWindow内容: 在此示例中,我使用CSS Grid使RadWindow的内容具有响应性。

        .sectionSearch {
            display: grid;
            grid-gap: 3px;
            grid-template-columns: repeat(auto-fit, 200px);
            align-items: end;
            max-width: 809px;
        }

RadWindow响应度:

每个this文章都可以将视口设置为屏幕的百分比。然后,您可以使用JavaScript媒体查询来调整视口的高度和宽度的百分比,具体取决于屏幕的大小。

结合包括this在内的一些帖子的修改,以下示例解决方案可以满足我对RadWindow的响应需求。

          var $ = $telerik.$;
        var radwindow;

        function pageLoad() {
            radwindow = $find("<%= radwindow.ClientID%>");
        }

        $(window).resize(function () {
            if (radwindow.isVisible()) {
                setWindowsize();
            }
        });

        function setWindowsize() {

            //var viewportWidth = $(window).width();
            //var viewportHeight = $(window).height();

            /* ==================================================== */

            // media query event handler
            if (matchMedia) {
                var mqls = [ // array of media queries
                    window.matchMedia("(min-width: 0px) and (max-width: 399px)"),
                    window.matchMedia("(min-width: 400px) and (max-width: 600px)"),
                    window.matchMedia("(min-width: 600px) and (max-width: 800px)"),
                    window.matchMedia("(min-width: 800px) and (max-width: 1000px)"),
                    window.matchMedia("(min-width: 1000px) and (max-width: 4000px)")
                ]

                for (i = 0; i < mqls.length; i++) { // loop though media queries
                    mqls[i].addListener(WidthChange); // listen for queries
                    WidthChange(mqls[i]); // call handler func at runtime
                }
            }

            // media query change
            function WidthChange(mql) {

                if (mqls[0].matches) {
                    var viewportWidth = $(window).width();
                    var viewportHeight = $(window).height();
                    radwindow.setSize(Math.ceil(viewportWidth * 90 / 100), Math.ceil(viewportHeight * 90 / 100));
                } else if (mqls[1].matches) {
                    var viewportWidth = $(window).width();
                    var viewportHeight = $(window).height();
                    radwindow.setSize(Math.ceil(viewportWidth * 90 / 100), Math.ceil(viewportHeight * 60 / 100));
                } else if (mqls[2].matches) {
                    var viewportWidth = $(window).width();
                    var viewportHeight = $(window).height();
                    radwindow.setSize(Math.ceil(viewportWidth * 90 / 100), Math.ceil(viewportHeight * 40 / 100));
                } else if (mqls[3].matches) {
                    var viewportWidth = $(window).width();
                    var viewportHeight = $(window).height();
                    radwindow.setSize(Math.ceil(viewportWidth * 90 / 100), Math.ceil(viewportHeight * 40 / 100));
                } else if (mqls[4].matches) {
                    var viewportWidth = $(window).width();
                    var viewportHeight = $(window).height();
                    radwindow.setSize(Math.ceil(viewportWidth * 70 / 100), Math.ceil(viewportHeight * 45 / 100));
                }
            }
                radwindow.center();
            }
