回发后未调用模态对话框的 onshow
Modal dialog's onshow not called after postback
我有一个 Bootstrap 模态对话框,当用户单击 jQuery 数据 table 中的 "Edit" 时,我用它来填充数据。此模式上有一个取消和提交按钮。
当我打开模式并单击取消然后 select 另一个 table 行并单击 "Edit" 时,一切都很好;每次单击 "Edit" 时,数据都会正确填充。但是,如果我通过单击模态上的 "Submit" 进行回发,然后再次单击 "Edit",模态打开并且没有数据。
我正在使用模态的 on('show.bs.modal', ...) 来填充它,并且在回发完成后它永远不会被击中。
// This is called when "Edit" in data table row is clicked
function showEdit(var1, var2) {debugger
$('#hfVar1').val(var1);
$('#hfVar2').val(var2);
showEditModal();
}
function showEditModal() {debugger
$("#spnEditHeader").text("Edit Something");
$('#editModal').modal('show');
}
$(document).ready(function () {
// This populates the jQuery data table
showTable(somthing, anotherThing);
// This is executed as long there is no postback;
// once a postback is perfoemd this is not hit, modal not populated
$('#editModal').modal({
keyboard: true,
backdrop: "static",
show: false
}).on('show.bs.modal', function (e) {debugger
var var1= $('#hfVar1').val();
var var2= $('#hfVar2').val();
//make ajax call to populate items
populateMPOOEdit(var1, var2);
});
....
});
//This is the button in modal that causes postback
<div class="modal-footer">
<div id="divEditButtons" style="text-align: center;">
<button id="btnCancel" class="btn btn-info2" data-dismiss="modal" aria-hidden="true" aria-label="Cancel">Cancel</button>
<button id="btnSubmit" class="btn btn-primary" aria-hidden="true" aria-label="Update">Update</button>
</div>
</div>
// "Submit" button's click handler
$(document).on("click", "#btnSubmit", function (event) {
// Validate data (client side validation)
var isValid = validateUpdate();
// Also need a server side validation checking for duplicate name, using ajax to do this
$.ajax({
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
url: '<%= ResolveUrl("services/mpoo.asmx/NameExists") %>',
cache: false,
data: JSON.stringify({ "Name": name }),
}).done(function (data) {
var result = data.d;
if (result != '') {
nameExists = JSON.parse(data.d);
if (nameExists == "true") {
$("#lblErrName").text("Duplicate Name");
$("#lblEditErrName").show();
isValid = false;
}
if (isValid) {
__doPostBack('btnSubmit', JSON.stringify({
action: "SaveUpdate", Var1: var1, ..., Varn: varn
}));
$('#editModal').modal('hide');
}
}
});
return false; // to prevent modal from closing if there are errors on page
});
像这样创建一个函数:
//basically everything you had in your document.ready function
function myJsFunc() {
// This populates the jQuery data table
showTable(somthing, anotherThing);
// This is executed as long there is no postback;
// once a postback is perfoemd this is not hit, modal not populated
$('#editModal').modal({
keyboard: true,
backdrop: "static",
show: false
}).on('show.bs.modal', function (e) {debugger
var var1= $('#hfVar1').val();
var var2= $('#hfVar2').val();
//make ajax call to populate items
populateMPOOEdit(var1, var2);
});
....
}
然后在代码隐藏的 Page_Load 事件处理程序中,尝试将此:
Page.ClientScript.RegisterStartupScript(this.GetType(), "some random name for your script", "myJsFunc();", true);
