selectpicker下拉多选框ajax异步或者提前赋值=》默认值

Bootstrap select多选下拉框赋值

success: function (data) {
var oldnumber = new Array();
$.each(data, function (i) {
oldnumber.push(data[i].id);
});
$('#editcolor .selectpicker').selectpicker('val', oldnumber);//默认选中
$('#editcolor .selectpicker').selectpicker('refresh');
}

上面是ajax获取默认值,记得selectpicker是通过id来操作的,

<div class="col-md-8" id="editcolor">
<select placeholder="请选择颜色" id="selectpickerallstr"
name="selectpickerallstr"
class="selectpicker show-tick form-control"
data-style="btn-success" multiple data-live-search="true">
</select>
</div>

你们可以参考我前面的一篇文章,我再贴一遍获取代码

//select颜色
var loadTemplateColor = function () {
$.ajax({
type: 'GET',
url: root + '/mycolor',
success: function (data) {
var data = eval(data);
$.each(data, function (i) {
$("<option value='" + data[i].id + "'>" + data[i].text + "</option>")
.appendTo(".selectpicker");
});
$('.selectpicker').selectpicker({
//我是对所有的selectpicker操作一次性赋值,如果你想单独赋值,好ok,那么就这样赋值:
//appendTo("#editcolor .selectpicker"),就这样,在你select元素上面罩上一个div,
//用div的id就可以标记你要操作的selectpicker,也就是你想操作的select元素标签了
  style: 'btn-info',
size: 8
})
}
});
}

一次搞定一个值的赋值:

$('#editcolor .selectpicker').selectpicker('val', 1);//默认选中
$('#editcolor .selectpicker').selectpicker('refresh');

一次搞定很多值的赋值:

success: function (data) {
var oldnumber = new Array();
$.each(data, function (i) {
oldnumber.push(data[i].id);
});
$('#editcolor .selectpicker').selectpicker('val', oldnumber);//默认选中
$('#editcolor .selectpicker').selectpicker('refresh');
} 动态赋值

<select id="filetype" name="filetype" class="selectpicker show-tick dropup" data-live-search="true" onchange="filetypeChange();"></select>

初始化调用 getdata4select("filetype","FILE_TYPE");

/**
* 根据字典类型查询字典数据,供bootstrap select使用
* @param id
* @param dicttype
*/
function getdata4select(id,dicttype){
var url ='/yh/com/dominsoft/act/YHTypeHandleAct/getItemType.act?type='+dicttype;
var json = getJsonRs(url);
if(json.rtState == "0"){
var rtData = json.rtData;
var typeData = rtData.typeData;
jQuery('#'+id).append("<option value='' >请选择</option>");
for (var i = 0; i < typeData.length; i++) {
jQuery('#'+id).append("<option value=" + typeData[i].typeId + " >" + typeData[i].typeDesc + "</option>");
}
}
jQuery('#'+id).selectpicker();
}
