我为MySQL数据库创建了一个管理面板,当我单击“编辑”按钮时,我想打印Bootstrap multi select中的所有数据。如果我不使用Bootstrap多项选择,而仅使用普通的多项选择,那么它将起作用。我该怎么办?
这是它的样子(在按钮中,它显示当前数据,但是当我打开时,它没有显示在选择菜单中):
<select name="classification[]" id="classification" multiple="multiple">
<?php
while($row = $classificationResult -> fetch_array()) {
?>
<option value="<?php echo $row['classification_id'];?>"><?php echo $row['name'];?></option>
<?php
}
?>
</select>
<script>
// If I didn't add the multi select jquery, it's working
$('#classification').multiselect({
nonSelectedText: 'Select Framework',
maxHeight : 400,
includeSelectAllOption : false,
enableFiltering : false,
buttonWidth : '100%',
dropRight : true
});
$(document).on('click', '.edit_data', function(){
$("#classification option").prop("selected", false);
var data_id = $(this).attr("id");
$.ajax({
url:"fetchRole.php",
method:"POST",
data:{'data_id':data_id},
dataType:"json",
success:function(data){
$.each(data.classifications, function(i, e) {
$("#classification option[value='" + e + "']").prop("selected", true);
});
$('#data_id').val(data.id);
$('#insert').val("Edit");
$('#add_data_Modal').modal('show');
}
});
});
</script>
$query2 = $conn -> prepare("SELECT classification.classification_id AS class_id
FROM classification
LEFT JOIN role_classification ON classification.classification_id = role_classification.classification_id
WHERE role_classification.role_id = ?");
$query2 -> bind_param('i', $role['id']);
$query2 -> execute();
$result2 = $query2 -> get_result();
$query2 -> close();
while ($classification = $result2 -> fetch_assoc()) {
$classificationIdList[] = $classification["class_id"];
}
$return = array_merge($role, ["classifications" => $classificationIdList]);
echo json_encode($return);

使用.prop("selected", true)
设置新的选定选项后,您需要刷新多选。
$.each(data.classifications, function(i, e) {
$("#classification option[value='" + e + "']").prop("selected", true);
});
$('#classification').multiselect('refresh');
refresh
方法的说明:
此方法用于根据以下内容刷新选中的复选框: 选择中当前选择的选项。
