<div>
<div class="mycontainer">
<table width="50%">
<tr>
<td width="50%">組:
<select id="group" name="group" style="width: 70%">
</select>
</td>
<td width="=50%">成員:
<select id="tester" name="tester" style="width: 70%">
</select>
</td >
</tr>
</table>
</div>
</div>
</body>
</html>
javascript:
<script>
$('#group').select2({
placeholder: 'select a group',
ajax: {
url: "/group",
dataType: 'json',
processResults: function(data) {
return {
results: $.map(data, function(item) {
return {
text: item.text,
id: item.id
}
})
};
},
}
});
$('#tester').select2({
placeholder: 'select a tester'
});
// group被選擇時,tester從後臺獲取資料並展示到前端
$('#group').on('select2:select', function(evt) {
//清空select2的options
$("#tester").empty();
$('#tester').select2({
placeholder: 'select a tester',
ajax: {
url: "/tester",
type: 'get',
dataType: 'json',
data: {
'group': $("#select2-group-container").html()
},
processResults: function(data) {
return {
results: $.map(data, function(item) {
return {
text: item.text,
id: item.id
}
})
};
},
}
});
});
</script>
效果如下:
