我正在使用 select2 插件来加载远程数据。我正在使用一个返回 JSON 数据的 aspx 页面,并将其分配给 select2 插件。用户从 select2 文本框中选择一些值后,我强制页面回发。回发后,我使用以下代码重新加载以设置 select2 文本框中的文本。
var data = { "PatientID": "XYX", "Email": "testing@gmail.com" };
$('#e6').select2('val', '123');
但系统抛出以下错误:cannot call val() if initSelection() is not defined
即使我定义了 init,我也无法设置该值。我正在使用以下代码。请帮助我在回发后在 select2 文本框中设置值。
$(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": "testing@gmail.com" };
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": "testing@gmail.com" };
//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();
});
});
