W3.JS ma’lumotlarni ko‘rsatish
HTML’da ma’lumotlarni ko‘rsatish:
w3.displayObject(selector)
Foydalanish oson
Ma’lumotlaringiz uchun joy ajratish maqsadida istalgan HTML elementga shunchaki {{ }} qavslarini qo‘shing:
Misol
<div id="id01">
{{firstName}} {{lastName}}
</div>
So‘ngra ma’lumotlarni HTML’ingizda ko‘rsatish uchun w3.displayObject’ni chaqiring:
Misol
<script>
var myObject = {"firstName" : "John", "lastName" : "Doe"};
w3.displayObject("id01", myObject);
</script>
Birinchi parametr — foydalaniladigan HTML elementning id’si (id01).
Ikkinchi parametr — ko‘rsatiladigan ma’lumotlar obyekti (myObject).
Kattaroq obyektni ko‘rsatish
W3.JS imkoniyatlarini namoyish qilish uchun kattaroq JavaScript obyektini (myObject) ko‘rsatamiz.
Bu obyekt CustomerName, City va Country xususiyatlariga ega mijoz obyektlaridan iborat massivdir:
myObject
var myObject = {"customers":[
{"CustomerName":"Alfreds Futterkiste","City":"Berlin","Country":"Germany"},
{"CustomerName":"Around the Horn","City":"London","Country":"UK"},
{"CustomerName":"B's Beverages","City":"London","Country":"UK"},
{"CustomerName":"Blauer See Delikatessen","City":"Mannheim","Country":"Germany"},
{"CustomerName":"Bon app'","City":"Marseille","Country":"France"},
{"CustomerName":"Bottom-Dollar Marketse","City":"Tsawassen","Country":"Canada"},
{"CustomerName":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"}
]};
Ochiladigan ro‘yxatni to‘ldirish
Misol
<select id="id01">
<option w3-repeat="customers">{{CustomerName}}</option>
</select>
<script>
w3.displayObject("id01", myObject);
</script>
Ro‘yxatni to‘ldirish
Misol
<ul id="id01">
<li w3-repeat="customers">{{CustomerName}}</li>
</ul>
<script>
w3.displayObject("id01", myObject);
</script>
w3.displayObject’ni w3.includeHTML bilan birgalikda ishlatish
Veb-sahifaga HTML fragmentlarini qo‘shganingizda, qo‘shilgan HTML’ga bog‘liq boshqa funksiyalar HTML to‘liq qo‘shilib bo‘lmaguncha bajarilmasligini ta’minlashingiz kerak.
Kodni "ushlab turish"ning eng oson yo‘li — uni callback funksiyasiga joylashtirish.
Callback funksiyasini w3.includeHTML() funksiyasiga argument sifatida qo‘shish mumkin:
Misol
<div w3-include-html="list.html"></div>
<script>
w3.includeHTML(myCallback);
function myCallback() {
w3.displayObject("id01", myObject);
}
</script>
Belgilash katakchalarini (checkbox) to‘ldirish
Misol
<table id="id01">
<tr w3-repeat="customers">
<td>{{CustomerName}}</td>
<td><input type="checkbox" {{checked}}"></td>
</tr>
</table>
<script>
w3.displayObject("id01", myObject);
</script>
Klasslarni to‘ldirish
Misol
<table id="id01">
<tr w3-repeat="customers" class="{{Color}}">
<td>{{CustomerName}}</td>
</tr>
</table>
<script>
w3.displayObject("id01", myObject);
</script>
Jadvalni to‘ldirish
Misol
<table id="id01">
<tr>
<th>Customer</th>
<th>City</th>
<th>Country</th>
</tr>
<tr w3-repeat="customers">
<td>{{CustomerName}}</td>
<td>{{City}}</td>
<td>{{Country}}</td>
</tr>
</table>
<script>
w3.displayObject("id01", myObject);
</script>
<select> elementini to‘ldirish
Misol
<select id="id01">
<option w3-repeat="x in cars">{{x}}</option>
</select>
<script>
w3.displayObject("id01", {"cars" : ["Volvo", "Ford", "BMW", "Mercedes"]});
</script>
