我正在使用Select2选择框.
问题
占位符未显示在select2中.它始终显示在select2中选择的第一个选项.它会自动选择我想要显示占位符而不是它的第一个选项.
我的代码：
脚本：
<script type="text/javascript">
$(document).ready(function () {
var data = $('#test_skill').select2({
placeholder: "Please select an skill",allowClear: true
});
});
// I have also tried this: This is also not working
$('#test_skill').select2({
placeholder: {
id: '-1',// the value of the option
text: 'Please select an skill'
}
});
</script>
HTML：
<select class="skills_select2" required name="test_skill" id="test_skill">
<option value="1">TEST1</option>
<option value="2">TEST2</option>
<option value="3">TEST3</option>
</select>
解决方法
只需输入< option>< / option>在第一名选择：
$(document).ready(function() {
$selectElement = $('#test_skill').select2({
placeholder: "Please select an skill",allowClear: true
});
});
.skills_select2 {
width: 120px;
}
