The drop-down selection function is very common to us. This article mainly introduces jquery to implement two-level linkage drop-down selection (province and city selection) based on layui. It has certain practical value. Friends who need it can refer to it. I hope it can help everyone.
Let’s take a look at the simple effect first
##Go directly to the code<p class="layui-form-item"> <label class="layui-form-label">城市</label> <p class="layui-input-inline"> <select name="city" lay-filter="province"> <option value=""></option> <option value="11">北京市</option> <option value="12">天津市</option> <option value="13">河北省</option> <option value="14">山西省</option> <option value="15">内蒙古自治区</option> <option value="21">辽宁省</option> <option value="22">吉林省</option> <option value="23">黑龙江省</option> <option value="31">上海市</option> <option value="32">江苏省</option> <option value="33">浙江省</option> <option value="34">安徽省</option> <option value="35">福建省</option> <option value="36">江西省</option> <option value="37">山东省</option> <option value="41">河南省</option> <option value="42">湖北省</option> <option value="43">湖南省</option> <option value="44">广东省</option> <option value="45">广西壮族自治区</option> <option value="46">海南省</option> <option value="50">重庆市</option> <option value="51">四川省</option> <option value="52">贵州省</option> <option value="53">云南省</option> <option value="54">西藏自治区</option> <option value="61">陕西省</option> <option value="62">甘肃省</option> <option value="63">青海省</option> <option value="64">宁夏回族自治区</option> <option value="65">新疆维吾尔自治区</option> <option value="71">台湾省</option> <option value="81">香港特别行政区</option> <option value="82">澳门特别行政区</option> </select> </p> <p class="layui-input-inline"> <select name="city" id="city"> <option value=""></option> </select> </p> </p>
form.on('select(province)', function(data){ $.getJSON("/api/getCity?pid="+data.value, function(data){ var optionstring = ""; $.each(data.data, function(i,item){ optionstring += "<option value=\"" + item.code + "\" >" + item.name + "</option>"; }); $("#city").html('<option value=""></option>' + optionstring); form.render('select'); //这个很重要 }); });
{ "status": 200, "message": "result", "data": [ { "code": "3418", "name": "宣城市", "province": "34" }, { "code": "3417", "name": "池州市", "province": "34" }, { "code": "3416", "name": "亳州市", "province": "34" }, { "code": "3415", "name": "六安市", "province": "34" }, { "code": "3413", "name": "宿州市", "province": "34" }, { "code": "3412", "name": "阜阳市", "province": "34" }, { "code": "3411", "name": "滁州市", "province": "34" }, { "code": "3408", "name": "安庆市", "province": "34" }, { "code": "3407", "name": "铜陵市", "province": "34" }, { "code": "3406", "name": "淮北市", "province": "34" }, { "code": "3405", "name": "马鞍山市", "province": "34" }, { "code": "3404", "name": "淮南市", "province": "34" }, { "code": "3403", "name": "蚌埠市", "province": "34" }, { "code": "3402", "name": "芜湖市", "province": "34" }, { "code": "3401", "name": "合肥市", "province": "34" } ] }
