我正在使用select2插件來加載遠程數據。我正在使用返回JSON數據的aspx頁面,並將其分配給select2插件。用戶從select2文本框中選擇一些值後,我強制頁面回發。回發後,我使用下面的代碼重新加載設置在select2文本框中的文本。無法調用val()如果initSelection()未在select2插件中定義錯誤
var data = { "PatientID": "XYX", "Email": "[email protected]" };
$('#e6').select2('val', '123');
但系統拋出以下錯誤:cannot call val() if initSelection() is not defined
即使我定義的init,我不能設置值。我正在使用以下代碼。請在回發後幫我設置select2文本框的值。 !
$(document).ready(function() {
$("#e6").select2({
placeholder: "Search for a movie",
minimumInputLength: 1,
ajax: { // instead of writing the function to execute the request we use Select2's convenient helper
url: "data.aspx",
dataType: 'json',
quietMillis: 1000,
data: function (term, page) {
return {
name: term
};
},
initSelection: function (element, callback) {
var data = { "PatientID": "XYX", "Email": "[email protected]" };
callback(data);
},
results: function (data) {
var results = [];
$.each(data, function (index, item) {
results.push({
id: item['Email'],
text: item['PatientID']
});
});
return {
results: results
};
},
},
});
});
window.onload = function() {
var data = { "PatientID": "XYX", "Email": "[email protected]" };
//When this is called system is throwing error
//This code is required to show the value in select2 textbox after the post back
$('#e6').select2('val', data);
}
$(document).ready(function() {
$("#e6").on("select2-selecting", function (e) {
//alert("selecting val=" + e.val + " choice=" + JSON.stringify(e.choice));
var id = document.getElementById('<%= savebtn.ClientID %>');
document.getElementById('<%= hdnFld.ClientID %>').value = e.val;
id.value = e.val;
//causes post back
id.click();
});
});
'initSelection'不應該在'ajax'屬性中。 – user1983983
