select input's selected option is not working if I use v-model on select.
<p class="topics">fruits</p>
<select class="select" v-model="selectFruit">
<option selected value="">--all--</option>
<option :key="index" :value="item" v-for="(item,index) in fruitList">{{item}}</option>
</select>
if I don't use v-model, then selected is working. But I need that v-model bind for filter my array. But it looks like I can't use v-model and selected at the same time.
Use selected attribute

<select class="select" v-model="searchCity">
<option value="" selected>--全部--</option>
<option :value="item" v-for="item in uniqueCity">{{item}}</option>
</select>
Adding a bonus to the above answer, if you want to have a default placeholder but not a valid value (Like "Select country here") you can do it like this:
<select>
<option value="" selected disabled hidden>Select country here</option>
<option value="1">Bulgaria</option>
<option value="2">Serbia</option>
<option value="3">Cyprus</option>
</select>

I am trying to preselect (set as default) value from Angular 5 drop down.
There are three values and I am trying to set the second one with this code but it doesn't work. I can't make any changes in the component, only in the template.
<select [(ngModel)]="declaration.media" name="media" (change)="onChangeMedia()" class="form-control form-control-sm" required>
<option *ngFor="let media of mediaArray" value="{{media.value}}" selected = "{{media.value == '02'}}">{{media.text}}</option>
</select>
UPDATE: if I remove [(ngModel)] then it works, but no two way binding.
<select>
<option value="" selected disabled hidden>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
I want to disable and enable a select, using angular based on a condition.
<select [disabled]="!isContinentSelected" class="form-control" formControlName="country">
<option value="">Select Your Country</option>
<option *ngFor="let country of countries" value="{{country.id}}">{{country.name}}</option>
</select>
isContinentSelected returns true or false. But the is always enable even the condition is false. Im using Angular 5. How can I achieve this?
<select [attr.disabled]="isContinentSelected ? '': null" class="form-control" formControlName="country">
<option value="">Select Your Country</option>
<option *ngFor="let country of countries" value="{{country.id}}">{{country.name}}</option>
</select>
Please try with this code.
This works in my case.
How can I bind a value selected with aurelia?
I have this select bellow:
<select id="user" class="form-control" value.bind="filters[0].value" change.delegate="userDropdownChanged(filters[0].value)">
<option repeat.for="user of users" model.bind="user.uuid">${user.name}</option>
</select>
I tried bind the value, but it is showing the whole list of the select, it is a way to show just the user selected in my h1?
<h1 repeat.for="user of users" model.bind="user.uuid">${user.name} </h1>
If you do the following:
<select value.bind="selectedUser">
<option repeat.for="user of users" model.bind="user.uuid">${user.name}</option>
</select>
The value selected in your <select> will be bound to a variable in your viewmodel called selectedUser.
You can then bind that to your <h1> like so:
<h1>${selectedUser.name}</h1>
I'm using VBA to open a website, login, and navigate to a certain page. There is a dropdown with 8 options.
I used this code to change the dropdown to the value I want, but it always reverts back to the default as I continue. How do I lock this change in?
Set Element = IE.Document.getElementsByName("date_range")
Element.Item(0).Value = "custom"
Here's the page code:
<div class="SelectInput">
<select class="SelectInput-select" name="date_range">
<option value="all_time">All Time</option>
<option value="today">Today</option>
<option value="yesterday">Yesterday</option>
<option value="this_month">Month to date</option>
<option value="last_month">Last Month</option>
<option value="this_year">Year to date</option>
<option value="last_year">Last year</option>
<option value="custom">Between...</option>
</select>
<div class="SelectInput-arrows">...</div>
</div>
Thanks,

What is the correct way to bind a select element to an object (rather than a string value) but still have the HTML element submit a string value?
I've managed to get this working, but it almost seems like I'm exploiting a bug:
<select v-model="selected" v-on:change="price=selected.price">
<option v-for="item in items" v-bind:value="item" value="{{ item.id }}">{{ item.name }}</option>
</select>
This works as intended: the "selected" property is attached to the "item" object, but the form POSTs just the item's ID. However, if I reverse the order of the HTML attributes, so that value={{ item.id }} comes before v-bind:value="item", then the form POSTs "[Object]" rather than, e.g., "3".
The fact that it's so fragile makes me think I'm doing something wrong.
So what's the right way to handle this?
I had a similar situation in which I built several vue components that could be used both within a vue component or within a standard form.
<select v-model="selected" v-on:change="price=selected.price">
<option v-for="item in items" :value="JSON.stringify(item)">{{ item.name }}</option>
</select>
Appears to be what you are after. I also had success using a computed property or filter but I decided that stringify was most readable.
I fixed it by using this approach:
<select v-model="product">
<option v-for="obj in choices" :value="obj">{{ obj.name }}</option>
</select>
<input type="hidden" name="product" :value="choice.id">
In summary: don't give your select a name but give that name to your hidden input and provide the ID as value on that element instead.
I see in both the cases, HTML being rendered as following:
<select>
<option value="[object Object]">name1</option>
<option value="[object Object]">name2</option>
<option value="[object Object]">name3</option>
<option value="[object Object]">name4</option>
</select>
Case 1 : v-bind:value="item" value="{{ item.id }}" : fiddle
Case 2 : value="{{ item.id }}" v-bind:value="item" : fiddle
So both the cases are equivalent as far as HTML being rendered. Ideal way to do it without confusion will be just using v-bind:value="item" like following:
<select v-model="selected" v-on:change="price=selected.price">
<option v-for="item in items" v-bind:value="item">{{ item.name }}</option>
</select>
You should v-bind to item or item.id depending on what you want to assign to selected variable.
