Question

我在我的应用程序中使用插件Jquery SumoSelect Multi Select，我想知道如何切换占位符，重新加载选择的intance。

我在“select”实例中通过AJAX加载新选项，但占位符保持与开头设置的相同。

HTML选择

<Select id = "c_ba" multiple = "multiple" disabled> </select>

实例

 $("#C_ba").SumoSelect ({
placeholder "Neighborhoods", //initial placeholder
okCancelInMulti: true,
selectAll: true
});

在另一个选择中我为上面的选择充电：

$('#C_ci').Change(function (e) {
SelectValue var = $(this).val();

$ .ajax ({
type: 'GET'
url: 'rotinas.asp'
date: "action = carrega_bairros & cod_cidade = '+ SelectValue,
success: function (html) {

var str = html;
var arr = str.split ("###");
arraux var = new Array ();

var select = $("#c_ba"); //html select initial
var options = '';

select.css ({'display', 'none'});
select.empty ();

if (str! = '') {
for (var x = 0; x <arr.Length; x ++) {
arraux = arr [x] .Split ("...");
options + = "<option value = '" + arraux [0] + "'>" + arraux [1] + "</ option>";
}

select.append (options);
select [0] .sumo.enable (); // Enable the SUMO SELECT 
select [0] .sumo.reload (); // Reload With news options loads

// Here I would like to exchange the original placeholder "Neighborhoods" to the following placeholder (eg.): "Select the Neighborhoods"

} Else {
select [0] .sumo.disable ();
select [0] .sumo.reload ();
}
},

error: function (e) {
// Called When there is an error
console.log (e.Message);
}
});

根据Sumoselect的文档，select tag中的native placeholder属性具有最大优先级。因此，您可以在重新加载sumoselect之前更改select标记的占位符属性（使用jQuery attr（）方法）。

select.append(options);
select.attr("placeholder","Select the Neighborhoods");
select[0].sumo.enable();
select[0].sumo.reload();

修改占位符 - Jquery Sumoselect - 下拉列表
