HTML的select控件美化

JavaScript 前端之家
前端之家收集整理的这篇文章主要介绍了HTML的select控件美化，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

CSS：

div { padding: 3px; line-height: 34px; } .div-select-arrow { background-color: #fff; float: right; width: 40px; height: 100%; color: #999; cursor: default; } .div-select-arrow > div { border: solid 1px #999; margin: 2px; height: 34px; background-color: #f2f2f2; text-align: center; line-height: 34px; font-size: 22px; } .div-select-list { position: absolute; float: left; top: 100px; left: 100px; border: solid 1px #999; max-height: 300px; overflow: auto; background-color: #9f9; display: none; z-index: 9100; } .div-select-list .div-select-item:nth-child(2n+1) { background-color: #fff; } .div-select-item { height: 50px; line-height: 50px; padding-left: 3px; padding-right: 3px; background-color: #f2f2f2; word-break: keep-all; overflow: hidden; cursor: default; } .div-select-item-hover { background-color: #3399ff!important; } .div-select-selected { background-color: #3399ff !important; }

JS：

插件 function initDivSelect() { $(".div-select-target").each(function () { divSelectListIndex++; var select = $(this); if (select.css("display") == "none") { return; } else { select.css("display","none") } if (select.next("div").find(".div-select-list").length == 0) { select.after('
∨
'); $("body").append('
'); } var div = select.next("div"); var divText = div.find(".div-select-text"); var divSelect = div.find(".div-select"); var divArrow = div.find(".div-select-arrow"); var list = $(".div-select-list-" + divSelectListIndex); function updateText(item) { divText.find("div").html(item.html()); } select.find("option").each(function () { var option = $(this); var text = option.html(); var value = option.attr("value"); list.append('
'); list.find(".div-select-item:last").click(function () { var item = $(this); var value = item.attr("value"); select.val(value); select.change(); list.find(".div-select-selected").removeClass("div-select-selected"); item.addClass("div-select-selected"); updateText(item); list.hide(); }); list.find(".div-select-item:last").mouseenter(function () { var item = $(this); var selectedMark = list.find(".div-select-selected"); selectedMark.removeClass("div-select-selected"); selectedMark.addClass("div-select-selected-mark"); list.find(".div-select-item-hover").removeClass("div-select-item-hover"); item.addClass("div-select-item-hover"); updateText(item); }); }); list.mouseleave(function () { var selectedMark = list.find(".div-select-selected-mark"); if (list.find(".div-select-selected").length == 0) { selectedMark.addClass("div-select-selected"); updateText(selectedMark); } selectedMark.removeClass("div-select-selected-mark"); list.find(".div-select-item-hover").removeClass("div-select-item-hover"); }); if (select.attr("width")) { divSelect.width(select.attr("width") - 2); divText.width(divSelect.width() - divArrow.width()); if (select.attr("width") > list.width()) { list.width(divSelect.width()); } } div.keydown(function (e) { list.find(".div-select-selected-mark").removeClass("div-select-selected-mark"); list.find(".div-select-item-hover").addClass("div-select-selected"); list.find(".div-select-item-hover").removeClass("div-select-item-hover"); if (e.keyCode == 40) { var currentSelected = list.find(".div-select-selected"); var nextSelected = currentSelected.next(".div-select-item"); if (nextSelected.length == 0) { nextSelected = list.find(".div-select-item:first"); nextSelected.addClass("div-select-selected"); currentSelected.removeClass("div-select-selected"); list.scrollTop(0); } else { nextSelected.addClass("div-select-selected"); currentSelected.removeClass("div-select-selected"); var i = 0; while (nextSelected.position().top < 0 || nextSelected.position().top > list.height() - nextSelected.height()) { list.scrollTop(list.scrollTop() + nextSelected.height()); if (i++ > 100) break; } } updateText(nextSelected); return false; } if (e.keyCode == 38) { var currentSelected = list.find(".div-select-selected"); var nextSelected = currentSelected.prev(".div-select-item"); if (nextSelected.length == 0) { nextSelected = list.find(".div-select-item:last"); nextSelected.addClass("div-select-selected"); currentSelected.removeClass("div-select-selected"); list.scrollTop(list.find(".div-select-item").length * nextSelected.height()); } else { nextSelected.addClass("div-select-selected"); currentSelected.removeClass("div-select-selected"); var i = 0; while (nextSelected.position().top < 0 || nextSelected.position().top > list.height() - nextSelected.height()) { list.scrollTop(list.scrollTop() - nextSelected.height()); if (i++ > 100) break; } } updateText(nextSelected); return false; } if (e.keyCode == 13) { var selectedItem = list.find(".div-select-selected"); var value = selectedItem.attr("value"); select.val(value); list.hide(); select.change(); } }); divSelect.click(function () { $("a").bind("click",function () { $("a").unbind("click"); list.hide(); }); if (list.css("display") == "none") { list.show(); } else { list.hide(); } list.css("top",divSelect.offset().top + divSelect.height() + 1); list.css("left",divSelect.offset().left); if ($(window).scrollTop() + $(window).height() < list.offset().top + list.height() + 2) { list.css("top",$(window).scrollTop() + $(window).height() - list.height() - 2); } if (list.width() < divSelect.width()) { list.width(divSelect.width()); } var currentSelected = list.find(".div-select-selected"); if (currentSelected.position().top > list.height() - currentSelected.height()) { list.scrollTop(currentSelected.position().top - currentSelected.height() * 2); } return false; }); $("html,body").bind("click",function () { list.hide(); }); list.click(function () { return false; }); function initSelect() { list.find(".div-select-selected").removeClass("div-select-selected"); var matchItem = list.find(".div-select-item[value='" + select.val() + "']"); if (matchItem.length > 0) { matchItem.addClass("div-select-selected"); updateText(matchItem); } } initSelect(); select.change(function () { initSelect(); }); }); // $(".div-select-target").each }

如何使用：

第1步、引用CSS和JS：

第2步、给select控件加上class="div-select-target" width="200"，其中class="div-select-target"是必须的，width="200"是可选的。完整HTML代码如下：

<div style="border: solid 1px #f99; margin: 50px; padding: 50px;">
