[javascript] How to set value of input text using jQuery

I have an input text which is this:

<div class="editor-label">
    @Html.LabelFor(model => model.EmployeeId, "Employee Number")
</div>

<div class="editor-field textBoxEmployeeNumber">
    @Html.EditorFor(model => model.EmployeeId) 
    @Html.ValidationMessageFor(model => model.EmployeeId)
</div>

Which produce following html

<div class="editor-label">_x000D_
  <label for="EmployeeId">Employee Number</label>_x000D_
</div>_x000D_
_x000D_
<div class="editor-field textBoxEmployeeNumber">_x000D_
  <input class="text-box single-line" data-val="true" data-val-number="The field EmployeeId must be a number." data-val-required="The EmployeeId field is required." id="EmployeeId" name="EmployeeId" type="text" value="" />_x000D_
_x000D_
  <span class="field-validation-valid" data-valmsg-for="EmployeeId" data-valmsg-replace="true"></span>_x000D_
</div>

I want to set the value of this input text using jquery so i did this:

<script type="text/javascript" language="javascript">
    $(function() {
        $('.textBoxEmployeeNumber').val("fgg");
    });
</script> 

however, it is not working... what is the error in my syntax?

For element with id

<input id="id_input_text16" type="text" placeholder="Ender Data"></input>

You can set the value as

$("#id_input_text16").val("testValue");

Documentation here.

Using jQuery, we can use the following code:

Select by input name:

$('input[name="textboxname"]').val('some value')

Select by input class:

$('input[type=text].textboxclass').val('some value')

Select by input id:

$('#textboxid').val('some value')

In pure js it will be simpler

EmployeeId.value = 'fgg';

EmployeeId.value = 'fgg';

<div class="editor-label">_x000D_
  <label for="EmployeeId">Employee Number</label>_x000D_
</div>_x000D_
_x000D_
<div class="editor-field textBoxEmployeeNumber">_x000D_
  <input class="text-box single-line" data-val="true" data-val-number="The field EmployeeId must be a number." data-val-required="The EmployeeId field is required." id="EmployeeId" name="EmployeeId" type="text" value="" />_x000D_
  _x000D_
  <span class="field-validation-valid" data-valmsg-for="EmployeeId" data-valmsg-replace="true"></span>_x000D_
</div>

$(document).ready(function () {
    $('#EmployeeId').val("fgg");

    //Or
    $('.textBoxEmployeeNumber > input').val("fgg");

    //Or
    $('.textBoxEmployeeNumber').find('input').val("fgg");
});

this is for classes

$('.nameofdiv').val('we are developers');

for ids

$('#nameofdiv').val('we are developers');

now if u have an iput in a form u can use

$("#form li.name input.name_val").val('we are awsome developers');

Here is another variation for a file upload that has a nicer looking bootstrap button than the default file upload browse button. This is the html:

<div class="form-group">
        @Html.LabelFor(model => model.FileName, htmlAttributes: new { @class = "col-md-2  control-label" })
        <div class="col-md-1 btn btn-sn btn-primary" id="browseButton" onclick="$(this).parent().find('input[type=file]').click();">browse</div>
        <div class="col-md-7">
            <input id="fileSpace" name="uploaded_file"  type="file" style="display: none;">   @*style="display: none;"*@
            @Html.EditorFor(model => model.FileName, new { htmlAttributes = new { @class = "form-control", @id = "modelField"} })
            @Html.ValidationMessageFor(model => model.FileName, "", new { @class = "text-danger" })
        </div>
    </div>

Here is the script:

        $('#fileSpace').on("change", function () {
        $("#modelField").val($('input[name="uploaded_file"]').val());
