I have the following code written in Razor view in MVC in C#. I want to select one of the item based on value but it is not working. I confirmed that the variable Facilities contain value Un-Funded but it doesn't select this item.
<select id="facilities" class="form-control" style="width:200px;">
<option #{ if (Facilities == "Funded") { Response.Write(" selected "); } }>Funded</option>
<option #{ if (Facilities == "Un-Funded") { Response.Write(" selected "); } }>Un-Funded</option>
</select>
Here's screenshot of how HTML looks like. Notice it is not printing selected for any of the option.
I am using Response.Write which doesn't work in Razor view. Using #Html.Raw("some string") fixed the issue. So the code will look like this:
#{ if(Facilities == "Funded") { #Html.Raw("selected='selected'") } }
You can try to use js,so that if you have many options,you don't need to check on each option:
<select id="facilities" class="form-control" style="width:200px;">
<option value="Funded">Funded</option>
<option value="Un-Funded">Un-Funded</option>
</select>
<script>
$(function () {
$("#facilities").val("#Facilities");
//Or you can use $("#facilities").val(#Html.Raw(Json.Encode(Facilities)));
})
</script>
With MVC 5 you can use this method #: to insert your selected:
<select id="facilities" class="form-control" style="width:200px;">
<option value="Funded" #{ if (Facilities == "Funded") { #: selected="selected"
}}>
Funded
</option>
<option value="Un-Funded" #{ if (Facilities == "Un-Funded") { #: selected="selected"
}}>
Un-Funded
</option>
</select>

I have an HTML.DropDownList where I can set datavaluefield and datatextfield like the following,
<select>
<option value="Fruit">APPLE</option>
</select>
Even, I can able to set the ID to dropdown list using html attributes but Since I need to set the 'Id' to the option like following,
<select>
<option ID='1' value="Fruit">APPLE</option>
</select>
Can anyone share the idea on it...
You can use the id attribute to set the ID to the option tag and use this.value into the onchange callback with select element.
Below is the working example
document.getElementById("select1").onchange = function() {
if (this.value == 'Fruit') {
var optionID=document.getElementById('1');
alert(optionID.value);
}
if (this.value == 'Flower') {
var optionID=document.getElementById('2');
alert(optionID.value);
}
}
<select name="select01" id="select1" onchange="handleSelect()">
<option value="Fruit" id="1">Apple</option>
<option value="Flower" id="2">Rose</option>
</select>
Try this, It will alert your selected value
<select onchange="alert(this.value)">
<option id="1">APPLE</option>
<option id="2">Orange</option>
</select>
I created one View Model with two Entities. I am passing this view model to my MVC Razor view which have two html drop-downs for each entity respectively.
<select class="form-control" id="Employees" name="Employees">
#foreach (var employee in Model.Employees)
{
<option value="#employee.Id"> #employee.name </option>
}
</select>
<select class="form-control" id="Tasks" name="Tasks">
#foreach (var task in Model.Tasks)
{
<option value="#task.Id"> #task.name </option>
}
</select>
Employee table is the parent of Task table. What I want is getting all the tasks which are related to particular employee only. e.g. In Employee drop-down I select John, then in Tasks drop-down I should get all the tasks which are relative to John. I know how to do this with ajax. I am looking for some other solution.
Is it possible to do something like this:
#foreach (var task in Model.Tasks.Where(x=>x.employeeId == 'Selected in previous dropdown'))
{
<option value="#task.Id"> #task.name </option>
}
Html block
<select id="Employees">
<option value="">Select Employee</option>
<option value="1">Employee1</option>
<option value="2">Employee2</option>
</select>
<select id="Tasks">
<option value="">Select Task</option>
<option value="1" data-employee="1">Employee1Task1</option>
<option value="2" data-employee="1">Employee1Task2</option>
<option value="3" data-employee="1">Employee1Task3</option>
<option value="1" data-employee="2">Employee2Task1</option>
<option value="2" data-employee="2">Employee2Task2</option>
<option value="3" data-employee="2">Employee2Task3</option>
</select>
Script scetion
<script>
$(document).ready(function () {
//on page ready hide all task option
$("#Tasks").find('option').hide();
// set task as empty
$("#Tasks").val('');
// onchange of employee Drop down
$("#Employees").on('change', function () {
var selectedEmployee = $("#Employees").val();
if (selectedEmployee != '') {
$("#Tasks").find('option').hide();
$("#Tasks option[value='']").show();
$('*[data-employee="' + selectedEmployee + '"]').show();
}
else {
// if employee not selected then hide all tasks
$("#Tasks").find('option').hide();
$("#Tasks").val('');
}
});
});
</script>
Please populate country and state drop down list using MVC way by for each loop and use above script. The mandatory case is you have to render all cascade options
<select class="form-control" id="Employees" name="Employees">
#foreach (var employee in Model.Employees)
{
<option value="#employee.Id"> #employee.name </option>
}
</select>
<select class="form-control" id="Tasks" name="Tasks">
#foreach (var task in Model.Tasks)
{
<option value="#task.Id" data-employee="#task.EmployeeId"> #task.name </option>
}
</select>

If you want result on same page, then this might be useful,
this will be on your page, where you want result
<script>
function showSelectBox(str)
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("myresult").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","test.php?q="+str,true); // Pass value to another page Here->test
xmlhttp.send();
}
</script>
<select name='check' onchange="showSelectBox(this.value)">
<option>Select</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
<div id="myresult">
</div>
Now On test.php Simply Call Value & put select box,
<?php
$q = $_GET['q'];
for($i=1 ; $i<=$q; $i++)
{
echo '<select > </select>';
}
?>
I want to use a select menu to redirect to another page in Rails.
I tried to add link_to to the select tag but it does not work.
How can this be done?
You would need to use Javascript and the onClick event on the Select Element
<script type="text/javascript">
function navigate(value) {
switch (value) {
case "1":
document.location.href = "http://www.google.com";
break;
case "2":
document.location.href = "http://www.yahoo.com";
break;
}
}
</script>
<select onchange="navigate(this.value)" >
<option selected>Please Choose</option>
<option value="1"> this page </option>
<option value="2"> that page </option>
</select>
