在 ASP.NET Core MVC 的 PartialView 中使用 Ajax post select 模态为 null
Use Ajax post select modal in PartialView of ASP.NET Core MVC is null
Ajax代码
$(function(){
var form = $(this).parents('.modal').find('form');
var actionUrl = form.attr('action');
var sendData = new FormData(form.get(0));
$.ajax({
url: actionUrl,
method: 'post',
data: sendData,
processData: false,
contentType: false,
cache: false,
success: function (redata) {
...
},
error: function (message) {
alert(message);
}
})
})
}
在局部视图中,我使用selectobject#EmpSelect
向selectobject#RolesList
添加值和文本,然后使用 ajax post ID、标题、isVirtualGroup 和 RolesList 到控制器。
但 RolesList 始终为空,我该如何解决?
javascript代码
$('#AddRolesGroup').click(function () { $('#EmpSelect :selected').map(function (row, item) { console.log(item.text); $('#RolesList').append("<option value='" + item.value + "'>" + item.text + "</option>") }); });
查看 select object 部分
<div id="area">
<select id="EmpSelect" class="form-select col-md-12" size="8"
multiple aria-label="EmpSelect">
</select>
<button class="btn" type="button" id="ClearSelect">Clear Select Roles</button>
<select asp-for="RolesList" asp-items="Model.RolesList" class="form-select col-md-12" size="8"
multiple aria-label="RolesList">
</select>
</div>
您需要确保 select 在表格中并确保您已经 selected values.Here 是一个演示:
<form id="form1">
<div id="area">
<select id="EmpSelect" class="form-select col-md-12" size="8"
multiple aria-label="EmpSelect">
</select>
<button class="btn" type="button" id="ClearSelect">Clear Select Roles</button>
<select id="RolesList" name="RolesList" class="form-select col-md-12" size="8"
multiple aria-label="RolesList">
<option value="1">role1</option>
<option value="2">role2</option>
<option value="3">role3</option>
</select>
</div>
</form>
<button onclick="postdata()">postdata</button>
js:
function postdata() {
var sendData = new FormData($("#form1").get(0));
$.ajax({
url: "PostData",
method: 'post',
data: sendData,
processData: false,
contentType: false,
cache: false,
success: function (redata) {
//
},
error: function (message) {
alert(message);
}
})
}
操作:
public IActionResult PostData(string[] RolesList)
{
return Ok();
}
结果:
Ajax代码
$(function(){
var form = $(this).parents('.modal').find('form');
var actionUrl = form.attr('action');
var sendData = new FormData(form.get(0));
$.ajax({
url: actionUrl,
method: 'post',
data: sendData,
processData: false,
contentType: false,
cache: false,
success: function (redata) {

},
error: function (message) {
