I am trying to set a default value for a HTML select form. I've read the posts on setting a constant default value for a select form. However, I want the default value to be the variable shirt.Color, which is either Small, Medium, or Large depending on the shirt.
For example, if shirt.Color is Small, I want the select form to have Small selected; if shirt.Color is Medium, I want the select form to have Medium selected; if shirt.Color is Large, I want the select form to have Large selected.
I know how to set default values for text boxes using data-binding. I set the default shirt color using the following:
<div class="form-group">
<label class="control-label col-sm-2">Shirt Color</label>
<input type="text" name="color" data-bind="valueUpdate: 'input', value:shirt.Color" class="form-control" required />
</div>
Is there something similarly simple I could do for a select form? I'd rather not manually code each case for Small, Medium, and Large.
I have tried doing
<div class="form-group">
<label class="col-sm-2 control-label col-sm-2">Shirt Size:</label>
<select required name="type" data-bind="type: 'input', value: shirt.Size">
<option value="s">Small</option>
<option value="m">Medium</option>
<option value="l">Large</option>
</select>
</div>
However, this always defaults to the first option, Small.
You can use a
kendoDropDownList
for this.<div data-bind="kendoDropDownList: { data: shirtSizes, dataTextField: 'SizeName', dataValueField: 'SizeId', value: shirt.Size } />
Where
shirtColors
is an array containing ColorName and ColorId fields.var shirtSizess = [ { SizeId: 's', SizeName: 'Small' }, { SizeId: 'm', SizeName: 'Medium' }, { SizeId: 'l', SizeName: 'Large' } ];
