I have a express server that passes in information from a mongo db into a ejs file. I am trying to update an item in the db. I want to have the current item information entered in as placeholders.
Here is the ejs code I'm not sure how to select one option based on the info from the db.
<select name="category" id="Category" placeholder="<%= product.category %>">
<option value="vegetable">Vegetable</option>
<option value="fruit">Fruit</option>
<option value="dairy">Dairy</option>
</select>
I understand that to have an option as the placeholder you generally have to use <option selected>
Any suggestions are much appreciated.
Use a Ternary Operator
<select name="category" id="Category">
<option value="vegetable" <%=product.category==='vegetable' ? 'selected' : '' %>>Vegetable</option>
<option value="fruit" <%=product.category==='fruit' ? 'selected' : '' %>>Fruit</option>
<option value="dairy" <%=product.category==='dairy' ? 'selected' : '' %>>Dairy</option>
</select>

Despite there are 12 fruits in select reader says "13"
I use reactive forms within my app. In a certain form I want to display a required (Validators.required) select like this:
<select class="form-control"
[id]="dformControl.key"
[formControlName]="dformControl.key"
[multiple]="dformControl.multiple">
<option *ngIf="!dformControl.value"
value="undefined">
Choose ...
</option>
<option *ngFor="let opt of dformControl.options"
[value]="opt.value"
[selected]="dformControl.value == opt.value">
{{opt.label}}
</option>
</select>
The problem is whether I use value="undefined" or value="" the form control still is set to valid because it got a value. Do not present the value attribute results in value="Choose ...".
Am I using select with reactive forms in a false way or how would I be able to make the option "Choose ..." being not valid??
Assigning initial value of select control to null will do the trick. Try below,
model_property = null
....
this.fb.group({
....
'control_key' : [this.model_property, Validators.required]
...
})
Check this Plunker!!, Look into app/reactive/hero-form-reactive.component.ts file.
I updated the Plunker to include below and it seems to be working,
<select id="power" class="form-control"
formControlName="power" required >
// see the value is set to empty,
<option value="">Choose...</option>
<option *ngFor="let p of powers" [value]="p">{{p}}</option>
</select>
Hope this helps!!
What I do is add a blank option and when that is selected since there is no value it is not valid.
<select class="form-control"
[id]="dformControl.key"
[formControlName]="dformControl.key"
[multiple]="dformControl.multiple">
<option></option>
<option *ngFor="let opt of dformControl.options"
[value]="opt.value"
[selected]="dformControl.value == opt.value">
{{opt.label}}
</option>
</select>

Im a bit of a jQuery novice.
I have 5 options in a drop down menu.
I want to add a class in a div depending on which option is selected.
This class will then change the layout of the content using CSS.
Here is an example if it helps!
Thanks
<form>
<select>
<option id="1">layout 1</option>
<option id="2">layout 2</option>
<option id="3" selected>layout 3</option>
<option id="4">layout 4</option>
<option id="5">layout 5</option>
</select>
<div class="3">styled content</div>
</form>
You can use the ".attr()" to set the class attribute of the div onchange.
You're best to change the option id to value first. then:
$("select").change(function() {
$("div").attr("class", $(this).val());
});
(EDIT) Change it to:
$("select#np_blog_layout").change(function() {
$("div#changebox").attr("class", $(this).val());
});
What 'rudeovski ze bear' said, but if you still want to set it to the div's class to the selected elements id, here it is.
$('select').change(function() {
$('div').attr('class', $(this).attr('id'));
});
First off, you don't have to use id to your options. Put the values in value attribute. Put ID to your div and select so you can select them using jQuery.
<form>
<select Id="selectElement">
<option value="1">layout 1</option>
<option value="2">layout 2</option>
<option value="3" selected>layout 3</option>
<option value="4">layout 4</option>
<option value="5">layout 5</option>
</select>
<div id="styledContent" class="3">styled content</div>
</form>
On JS
//Attach event handler to select element's onchange event
$('#SelectElement').bind("change",changeStyle);
//The event handler
function changeStyle()
{
//Set class to selected value
$('#styledContent').class($('#SelectElement').val());
}
Before:
<input type='checkbox' name='killerFeature' id='killerFeature'
<%= param('killerFeature') ? ' checked' : ''%>
/>
Now:
<select name="killerFeature" id="killerFeature" class="select">
<option value="1">Enable</option>
<option value="0">Disable</option>
</select>
How do I insert the same checked (should be 'selected' now I guess?) condition in the select now?
This is a perl app, built using Mojolicious web framework.
Many thanks for your help!
Yes, the condition should be selected (selected="selected") but i belive you already figured that out from your other post :)
<select name="killerFeature" id="killerFeature" class="select">
<option value="1" selected="selected">Enable</option>
<option value="0">Disable</option>
</select>
Also from what i saw there inst a way to create the select like you can for the input as in the below example:
<%= input 'test', type => 'text' %>
So it would be something like:
<%== param('killerFeature') eq $my_var ? ' selected="selected"' : ''; %>
Ofc you would need to replace the above to your current variables and field names.
