背景：当option特别多时，一般的下拉框选择起来就有点力不从心了，所以使用multiselect是个很好的选择，可以通过输入文字来选择选项很方便，但是有一个需要下拉框联动，网上找了半天才找到解决方法，在此分享一下
1、先引入
<script src="~/Assets/js/bootstrap-multiselect.min.js"></script> <link href="~/Assets/css/bootstrap-multiselect.css" rel="external nofollow" rel="stylesheet" />
然后全局定义
function RegSelect() {
$('.multiselect').multiselect({
buttonClass: 'btn btn-white ',
enableFiltering: true,
enableHTML: true,
includeSelectAllOption: true,
selectAllText: '全选',
allSelectedText: '全部选中',
nonSelectedText: '请选择',
nSelectedText: '个被选中',
templates: {
button: '<button type="button" class="multiselect dropdown-toggle" data-toggle="dropdown"><span class="multiselect-selected-text"></span> <b class="fa fa-caret-down"></b></button>',
ul: '<ul class="multiselect-container dropdown-menu"></ul>',
filter: '<li class="multiselect-item filter"><div class="input-group"><span class="input-group-addon"><i class="fa fa-search"></i></span><input class="form-control multiselect-search" type="text"></div></li>',
filterClearBtn: '<span class="input-group-btn"><button class="btn btn-default btn-white btn-grey multiselect-clear-filter" type="button"><i class="fa fa-times-circle red2"></i></button></span>',
li: '<li><a tabindex="0"><label></label></a></li>',
divider: '<li class="multiselect-item divider"></li>',
liGroup: '<li class="multiselect-item multiselect-group"><label></label></li>'
}
});
}
只需要在页面加载时RegSelect();（只能调用一次，不然会出现问题）就可以了
2、两个下拉框
<div class="form-group">
<label for="RepairOrg" class="col-sm-3 control-label">维修单位</label>
<div class="col-sm-9">
@Html.DropDownList("RepairOrgUID", ViewBag.OrgList as List<SelectListItem>, "请选择", new { @class = "form-control multiselect", onchange = "OrgChange(this)", id = "RepairOrg" })
</div>
</div>
<div class="form-group">
<label for="RepairContact" class="col-sm-3 control-label">维修人</label>
<div class="col-sm-9">
@Html.DropDownList("RepairContactUID", ViewBag.ContactList as List<SelectListItem>, "请选择", new { @class = "form-control multiselect", id = "RepairContact" })
</div>
</div>
3、js代码
function OrgChange(obj, patientID) {
var RepairOrg = $(obj).val();
$.post("/TerminalManage/GetContactByOrg", { RepairOrg: RepairOrg }, function (data) {
var newCitys = new Array();
var obj = new Object();
obj = {
label: "请选择",
value: ""
};
newCitys.push(obj);
for (var i = 0; i < data.length; i++) {
obj = {
label: data[i].Text,
value: data[i].Value
};
newCitys.push(obj);
}
$("#RepairContact").multiselect('dataprovider', newCitys);
$('#RepairContact').multiselect('refresh');
});
}
以上所述是小编给大家介绍的基于BootStrap multiselect.js实现的下拉框联动，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对脚本之家网站的支持！
