Based on Semantic-UI docs, https://semantic-ui.com/modules/dropdown.html#multiple-selections
I have following code inside angular2 template:
<select id="thickness" name="thick" [(ngModel)]="form.thickness" multiple="multiple" class="ui multiple dropdown selection">
<option value="">Выбрать</option>
<option value="100">100 mm</option>
<option value="150">150 mm</option>
<option value="200">200 mm</option>
<option value="250">250 mm</option>
<option value="300">300 mm</option>
<option value="375">375 mm</option>
<option value="400">400 mm</option>
</select>
I'd like to get array of selected values from Select to angular model form.thickness
However, I am getting empty array.
inside ngOnInit I have $('#thickness').dropdown();
console.log($('#thickness').dropdown('get value')); gives empty array;
How to get values from dropdown multiple selection?
Suggesting that your code looks like this:
<div class="ui multiple selection dropdown">
<i class="dropdown icon"></i>
<div class="default text">Tag Multiple Categories</div>
<select multiple="" id="multi-select">
<option value="">Categories</option>
<option value="datastructure">Data Structure</option>
<option value="stack">Stack</option>
<option value="queue">Queue</option>
</select>
</div>
</div>
the following will return an array of selected values:
$("#multi-select").dropdown("get value")
Output:
["stack", "queue"]
Note:
Make sure not to have hidden input field in the html otherwise it returns a string value instead of array of values
You can still use select. Here's how to do it in Aurelia: form.html:
<select id="thickness" name="thick" multiple="" class="ui multiple dropdown selection" value.bind="thickness_selected">
<option value="">Выбрать</option>
<option value="100">100 mm</option>
<option value="150">150 mm</option>
</select>
form.ts:
export class form {
thickness_selected: number[] = [];
submit() {
const self = this;
for (let id of self.thickness_selected) {
console.log(id);
}
}
}
Solved by rewriting code to:
<div id="thickness" class="ui multiple selection dropdown">
<input name="thick" type="hidden">
<i class="dropdown icon"></i>
<div class="default text">Выбрать</div>
<div class="menu">
<div class="item" data-value="100">100 mm</div>
<div class="item" data-value="150">150 mm</div>
<div class="item" data-value="200">200 mm</div>
<div class="item" data-value="250">250 mm</div>
<div class="item" data-value="300">300 mm</div>
<div class="item" data-value="375">375 mm</div>
<div class="item" data-value="400">400 mm</div>
</div>
</div>
