wenzhixin Bootstrap Table Editable: Show Error on server validation - x-editable

Question

I am working on bootstrap table Editable. An extension of Wenzhixin Bootstrap Table.
Bootstrap Table Editable
I am using OnEditable to send data to the server (Using Laravel to handle the server request). I receive Error Codes in return about the outcome. But I can't seem to find a way to Show that Error on The Editable Popover OR prevent the new value to be replaced by old value. Like Error shows when We validate the Input.
I have checked the Editable->success but it only has NEW VALUE. Response parameter is always undefined.
Here is my code:
var table = $('#table');
table.bootstrapTable({
columns: [
{
field: 'roomType'
},
{
field: 'Mon',
editable: {
type: 'number',
title: 'Update Rates',
validate: function (v) {
if (!v) return 'Please Enter Rate Value';
if (parseFloat(v) < 0) return 'Rate should be greater than 0';
}
}
}
],
onEditableSave: function (field, row, oldValue, $el) {
var data = {
'_token': window.Laravel.csrfToken,
'Field': field,
'PK': row['_'+field+'_data'].pk,
'oldValue': oldValue,
'newValue': row[field]
};
$.post("Url", data)
.success(function(data, textStatus, xhr) {
if (data.success) {
}
else{
switch (data.code) {
case 400:
return data.msg;
break;
case 403:
return data.msg;
break;
case 401:
return data.msg;
break;
}
}
})
.fail(function(data, textStatus, xhr) {
return 'Something went wrong.';
});
}
});
I am expecting this kind of error to show:
Output To be Expected

Answer 1

I could not get the required output, to show the error on the popover. But I got a work around.
Sol: I am replacing the old value on error by $el[0].text = oldValue; and showing the error in some alert means.
Thanks
$.post(URL, data)
.success(function(data, textStatus, xhr) {
if (data.success) {
}
else{
switch (data.code) {
case 400:
$el[0].text = oldValue;
ShowError(data);
break;
case 403:
$el[0].text = oldValue;
ShowError(data);
break;
case 401:
$el[0].text = oldValue;
ShowError(data);
break;
}
}
})
.fail(function(data, textStatus, xhr) {
$el[0].text = oldValue;
ShowError('Something Went Wrong');
});
