I want to change Editorfor that display already data from database when i change input
i will take output of input and split it and put result in 2 EditorFor
<input type="text" value="Set Date" id="reservationtim onchange=myFunction()>
#Html.EditorFor(model => model.StartDate, new { htmlAttributes = new { #class = "form-control" }, id = "startDate" })
#Html.EditorFor(model => model.EndDate, new { htmlAttributes = new { #class = "form-control" } , id = "endDate" })
and the function :
<script>
function myFunction() {
var date = document.getElementById("reservationtime").value;
var res = date.split("-");
model => model.StartDate = res[0];
document.getElementById("startDate") = res[0];
document.getElementById("endDate") = res[1];
}
</script>
You're trying to set the element reference itself to the value you want. Rather you need to set the value attribute of the element reference:
document.getElementById("startDate").value = res[0];
Also, it looks like you're trying to mix server-side and client-side code here. Remember that JavaScript is not processed until the document has already been processed by the server and returned to the client. Once you're client-side, all that exists is just the DOM, which is created by the browser based on the HTML document the server sent down. In other words, the fact that you used EditorFor or whatever is completely lost. All you have is the result (i.e. HTML) of that call to EditorFor.
You should first correct your HTML, as some attributes are not specified correctly.
<input type="text" value="Set Date" id="reservationtime" onchange="myFunction()">
#Html.EditorFor(model => model.StartDate, new { #class = "form-control" } )
#Html.EditorFor(model => model.EndDate, new { #class = "form-control" } )
I don't know why you are explicitly setting id for above two editors. they by default take property name as ID. so I would suggest following script for it.
<script>
function myFunction() {
var date = document.getElementById("reservationtime").value;
var res = date.split("-");
model => model.StartDate = res[0];
if(res.length>1) {
document.getElementById("StartDate").value = res[0];
document.getElementById("EndDate").value = res[1];
// if you still want to set ID properties instead of using default use following
// document.getElementById("StartDate").value = res[0];
// document.getElementById("EndDate").value = res[1];
}
}
</script>

I Have the following code within my razor view that I want to action a button next to every response.
Once clicked I want it to copy response to actualresponse.
But I get the following error
Microsoft JScript runtime error: Unable to get value of the property 'foo': object is null or undefined.
#for (int i = 0; i < Model.Responses.Count(); i++)
{
<div class="col-md-4">
#Html.LabelFor(x => Model.Responses[i].Response, htmlAttributes: new { #class = "control-label"})
#Html.DisplayFor(x => Model.Responses[i].Response)
</div>
<input type="button" name="set_Value" id="#i" value="Copy Response to Actual Response" class="btn btn-success" dataset-foo="#Model.Responses[i].Response" onclick="setVale(this)" />
<div class="col-md-4">
#Html.LabelFor(x => Model.Responses[i].ActualResponse, htmlAttributes: new { #class = "control-label"})
#Html.TextAreaFor(x => Model.Responses[i].ActualResponse, htmlAttributes: new { #class = "from-control", #id = "actualResponse-" + i, rows = 5, columns = 40})
</div>
<script type="text/javascript">
function setValue(btn)
{
var id = btn.id;
var value = btn.value;
var foo = btn.dataset.foo;
document.getElementById('actualResponse-' + id).value = foo
}
</script>
}
Your for loop creates multiple copies of a function with the same name. The last function with the hardcoded id is the result you see.
You could just pass this into your click handler.
<input type="button" name="set_Value"
value="Copy Response to Actual Response" class="btn btn-success"
id = "#i"
data-foo = "#foo"
onclick="setVale(this)" />
Then you can stop that ugly mixing of Razor and JavaScript. And take the function out of the for loop so you only have one setValue() which will handle all instances of your buttons.
function setValue(btn) {
var id = btn.id;
var value = btn.value;
var foo = btn.dataset.foo;
}
In my form i have a chekbox and when i click the checkbox a textbox is enabled.
When i submit the form i got both values(checkbox and textbox)and the site refresh,after the refresh the checkbox is checked but the textbox is disabled but has the last insert value.
If i submit again without making something the textbox returns null and not the last insert value.
I want that the checkbox got the value from my model and change the behavior of the textbox disabled-property und if no new value will be insert,it should return the last insert value.
When i set the model property of false the checkbox is also checked.
Has anyone a idea what i can do ?
View:
#Html.TextBoxFor(m => m.FilterModel.FilterOrgNameValue, new { #class = "form-control", #id = "OrganisatioName", #disabled = "disabled" })
#Html.CheckBoxFor(m => m.FilterModel.FilterOrgNameIsCheckedValue, new { #class = "form-control", #id = "OrgNameChecked", #checked = (Model.FilterModel.FilterOrgNameIsCheckedValue ? "checked" : "unchecked")})
JavaScript:
$("#OrgNameChecked").click(function () {
$('#OrganisatioName').attr("disabled", $(this).is(':unchecked'));
});
Model:
public bool FilterOrgNameIsCheckedValue { get; set; }
Controller (Function which got called by submit):
public ActionResult Index(AdminOrganizationModel m)
{
AdminOrganizationModel model = new AdminOrganizationModel();
if(TempData["model"] != null)
{
m = (AdminOrganizationModel)TempData["model"];
}
if(m.FilterModel == null)
{
m.FilterModel = new AdminOrganizationFilterModel();
}
model = m;
OrganizationBusinessObject organizationBusinessObject = new OrganizationBusinessObject(DbContext);
var organizations = DbContext.GetAllEntitiesQueryable<Organization>();
organizations = FilterOrganizations(organizations, model);
InitializeLicenseList(1);
AdminOrganizationModelBuilder modelBuilder = new AdminOrganizationModelBuilder();
IList<AdminOrganizationModel> organizationsModels = modelBuilder.GetModelCollection(organizations);
model.Organizations = new AjaxGridFactory().CreateAjaxGrid(organizationsModels.AsQueryable(), 1, false, 10) as AjaxGrid<AdminOrganizationModel>;
return View(model);
}
Fields after submit
Simple Solution ;)
I added a simple if statement in the View:
<div class="col-sm-2">
#if (Model.FilterModel.FilterOrgNameIsCheckedValue)
{
#Html.TextBoxFor(m => m.FilterModel.FilterOrgNameValue, new { #class = "form-control", #id = "OrganisatioName"})
}
else
{
#Html.TextBoxFor(m => m.FilterModel.FilterOrgNameValue, new { #class = "form-control", #id = "OrganisatioName", #disabled = "disabled" })
}
</div>
I guess its not the best way but it works =)
my view contains
<div class="col-md-3 ">
#{
List<SelectListItem> deformitylevel = new List<SelectListItem>();
deformitylevel.Add(new SelectListItem { Value = "hip", Text = "Hip" });
deformitylevel.Add(new SelectListItem { Value = "knee", Text = "Knee" });
deformitylevel.Add(new SelectListItem { Value = "ankle", Text = "Ankle" });
deformitylevel.Add(new SelectListItem { Value = "other", Text = "Other" });
}
#Html.DropDownListFor(model => model.DeformityLevel, deformitylevel, "--Select Level -", new { #class = "form-control", #onchange = "showdeformitytextbox()", id = "deformitydropdown" })
#Html.ValidationMessageFor(model => model.DeformityLevel, "", new { #class = "text-danger" })
</div>
<div class="col-md-3">
#Html.EditorFor(model => model.DeformityLevel, new { htmlattributes = new { #class = "form-control", id = "deformitytextbox" ,style= "display:none"} })
</div>
My function is
function showdeformitytextbox() {
if ($("#deformitydropdown option:selected").text() == 'Other') {
$("#deformitytextbox").show();
}
else {
$("#deformitytextbox").hide();
}
}
When I select "Other" in dropdownlist it stores 'other' in the database instead of storing a value which is entered in #Html.EditorFor.
What I'm forgetting Help!!
As mentioned by others, to make this cleaner, it would be best if you separated the model fields for the drop down and the textbox. Even if you get it to work using the below code, it will lead to more work if you have to return to the page with the other value selected. That said, the following does properly submit the expected value in the textbox. The key concept is to set the dropdown to disabled as you submit.
Assuming your form has an id of submitForm specified as follows:
#using (Html.BeginForm("someActionName", "someControllerName", FormMethod.Post, new { #id="submitForm"}))
Then the following code will ensure that the drop down doesn't submit its value by intercepting the form submission:
$("#submitForm").submit(function () {
if ($("#deformitydropdown option:selected").text() === "Other") {
$("#deformitydropdown").attr("disabled", true);
} else {
$("#deformitydropdown").removeAttr("disabled");
}
});
I would change the names of your current controls and make a hidden form element for DeformityLevel. Then set its value in javascript based on DropdownList and textbox change events.
***Something like this (jq not verified, just for illustration)
<select id="DeformityLevel_DDL">
<option></option>
<option></option>
<option></option>
</select>
<input type="text" id="DeformityLevel_TB" />
<input type="hidden" id="DeformityLevel" name="DeformityLevel" />
<script>
$(document).ready(function () {
$('#DeformityLevel_DDL').change(function () {
if ($(this).val() != 'other') {
$('#DeformityLevel').val(this.val());
}
});
$('#DeformityLevel_TB').on('change', function () {
$('#DeformityLevel').val($(this).val());
});
});
</script>
Well, your function only display the #deformitytextbox input, when the value entered there changes you should also update the model property.
If the form submits automatically on select change you should use preventDefault.
Try now with TextBox, your parameter for htmlAttributes is incorrect. Try:
<div class="col-md-3 ">
#Html.DropDownList("DeformityLevel", deformitylevel, "--Select Level -", new { #class = "form-control", #onchange = "showdeformitytextbox()", id = "deformitydropdown" })
#Html.ValidationMessage("DeformityLevel", "", new { #class = "text-danger" })
</div>
<div class="col-md-3">
#Html.TextBox("DeformityLevel", null, new { #class = "form-control", id = "deformitytextbox", style = "display:none;" })
</div>
<script>
function showdeformitytextbox() {
if ($("#deformitydropdown option:selected").text() == 'Other') {
$("#deformitytextbox").show();
}
else {
$("#deformitytextbox").hide();
}
}
</script>
In my index.cshtml file I have a razor element (#Html.EditorFor) that's a text box. Javascript isn't recognizing the element. If I change the element type to a non-razor syntax then javascript can see it. Am I missing some syntax here.
index.cshtml
<div class="jumbotron">
<h1>my application</h1>
#using (Html.BeginForm("Results", "Home", FormMethod.Post))
{
<div class="form-group">
//javascript can't see mainpagequery
#Html.EditorFor(model => model.SearchQuery, new { htmlAttributes = new { #class = "form-control", id = "mainpagequery" }})
#Html.ValidationMessageFor(model => model.SearchQuery, "", new { #class = "text-danger" })
//javascript can see mainpagequery in the non razor element here
<input type="text" class="form-control" placeholder="Search" id="mainpagequery">
</div>
<button type="submit" class="btn btn-default">Search</button>
}
Here is my javascript. If I use razor then 'mainpagequery' is underlines because it can't see it, if I use html then it's fine. I know I'm hitting my javascript because I see the alert message pop up.
$(document).ready(function () {
console.log("ready!");
alert("mainpage autocomplete function entered");
var input = document.getElementById('mainpagequery');
var options = {
types: ['(cities)'],
componentRestrictions: { country: "us" }
};
var mainpagequery = new window.google.maps.places.Autocomplete(input, options);
});
In case of #Html.EditorFor your id get overriden to model's property name.
If you find element using f12 you will find it as follows. (Notice id "SearchQuery124" I just renamed it to something)
So in your case in make change like
$(document).ready(function () {
console.log("ready!");
alert("mainpage autocomplete function entered");
var input = document.getElementById('SearchQuery').value;
console.log(input);
var options = {
types: ['(cities)'],
componentRestrictions: { country: "us" }
};
var mainpagequery = new window.google.maps.places.Autocomplete(input, options);
});
Try this
Instead of #Html.EditorFor use
#Html.TextBoxFor(model => model.SearchQuery, new { #class = "form-control" , id = "mainpagequery"})
I have four #Html.TextBoxFor as the code shows below
#Html.TextBoxFor(model => model.money, "money", new { #class = "required numeric", id = "money", Value = String.Format("{0:C}", Model.money )})
#Html.TextBoxFor(model => model.money2, "money2", new { #class = "required numeric", id = "money2", Value = String.Format("{0:C}", Model.money2 )})
#Html.TextBoxFor(model => model.money3, "money3", new { #class = "required numeric", id = "money3", Value = String.Format("{0:C}", Model.money3 )})
#Html.TextBoxFor(model => model.TotalMoney, "TotalMoney", new { #class = "required numeric", id = "TotalMoney", Value = String.Format("{0:C}", Model.TotalMoney )})
I previously used four
<input type="text" id="money" onkeyup="sum();" name="money" value="#Model.money" />
in order to add money, money 2 and money 3 together to produce a result in TotalMoney but it gives me a decimal problem and if I use TextBoxFor I don't get the decimal problem however I loose the calculation functionality.
JavaScript code I'm using is
<script type="text/javascript">
function sum() {
var txtFirstNumberValue = document.getElementById('money').value;
var txtSecondNumberValue = document.getElementById('money2').value;
var txtThirdNumberValue = document.getElementById('money3').value;
var result = parseFloat(txtFirstNumberValue) + parseFloat(txtSecondNumberValue) + parseFloat(txtThirdNumberValue);
if (!isNaN(result)) {
document.getElementById('TotalMoney').value = result.toFixed(2);
}
}
</script>
And the JS works great with input but won't work at all with TextBoxFor, how can I adapt the JS into my TextBoxFor?
I had to adapt Stephen's answer to work as I needed it too. Stephen's answer as shown below worked great as it allowed my values to be displayed as for example £15.15, thus removing the 2 decimal places. However the only problem was I still lost the functionality of adding money, money 2 and money 3 together to automatically produce a total in TotalMoney.
#Html.TextBoxFor(m => m.money, "{0:C}", new { #class = "required numeric" })
The slight change I made to Stephen's code is shown below. This removed the £ symbol however it also ensured my values retained 2 decimal places (i.e £13.12) and allowed my calculation functionality to work again.
#Html.TextBoxFor(model => model.money, "{0:0.00}", new { #class = "required numeric", onkeyup = "sum()" })
