我遇到错误:无法对空引用执行运行时绑定。
尝试通过ajax调用发回到我的控件时出现错误。
$('#main-content-submit').click(function () {
var labelArray = [];
labelArray = $("input:checkbox[name=type]:checked").map(function () {
return $(this).closest('label').text();
}).get();
console.log(labelArray);
event.preventDefault();
//Ajax call to get all months and years
$.ajax({
type: 'POST',
url: '/Home/Extract',
data: JSON.stringify({ name: labelArray}),
contentType: 'application/json',
success: function (_result) {
},
error: function (err, _result) {
alert("Error in Extract" + err.responseText);
}
});
return false;
});
> Here is my view: I am getting the error and it is highlighting my @ViewBag.StatementYears items.
<div class="form-group">
<label class="year" for="Year">Step 2 - Select Statement Year(s) :</label>
<div id="checkboxes" class="grid-container2">
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_1"> @ViewBag.StatementYears[0]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_2"> @ViewBag.StatementYears[1]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_3"> @ViewBag.StatementYears[2]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_4"> @ViewBag.StatementYears[3]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_5"> @ViewBag.StatementYears[4]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_6"> @ViewBag.StatementYears[5]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_7"> @ViewBag.StatementYears[6]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_8"> @ViewBag.StatementYears[7]</label>
<label><input class="year" type="checkbox" name="type" id="chkBoxYear_9"> @ViewBag.StatementYears[8]</label>
</div>
<button id="selection" class="select-all-years">Select All Years</button>
</div>
这是我的控制器
[HttpPost]
public ActionResult Extract(string[] name)
{
return View("Index");
}
答案 0 :(得分:0)
您的 @ ViewBag.StatementYears 似乎是在 Index 控制器中定义的,而不是在 Extract 控制器中定义的。您试图返回一个视图而不定义其ViewBag。我可以为您提供2种解决方案:
return RedirectToAction("Index")
代替return View("Index")
。
