<script>
$('#brand_id').on('change',function(e){
console.log(e);
var brand_id = e.target.value;
//ajax
$.get('/product_id?brand_id =' + brand_id, function(data));
//success data
$.each(data, function(upload_form, product_cat){
$('product_category').empty();
$('product_category').append('<option value="'+ product_cat.id +'">'+ product_cat.product_hierarchy +'</option>');
});
});
上面是我的Jquery代码检查这个,并指出我是什么问题。
<form enctype="multipart/form-data" action="{{action('BrandController@upload_csv')}}" method="post">
Brand Code
<select name="brand_id" id="brand_id" Select="" class="form-control">
<option value="">--Select Brand Code--</option>
<?php foreach ($brands as $row) { ?>
<option value="<?= $row->brand_id ?>"><?= $row->brand_name ?></option>
<?php } ?>
</select>
Product Id
<select name="product_category" id="product_category" Select="" class="form-control">
</select>
Status
<select name="status" Select="" class="form-control">
<option value="">--Select Product Status--</option>
<option value="1">Yes</option>
<option value="0">No</option>
</select>
<input type="hidden" name="_token" value="<?= csrf_token(); ?>">
Upload Valid csv file
<input type="file" name="csv" required class="form-control">
<br/>
<input type="submit" value="Upload" class="btn btn-primary">
</form>
这是我的表格。在表单中有一个选择,其中onchange元素我想在下一个选择中显示子类别。下面是我的路线文件代码。
Route :: get('/ product_id',function(){ $ brand_id =输入:: get('brand_id');
$product_id = product_hierarchy::where('bcategory_code','=',1)->get();
return Response::json($product_id);
});
答案 0 :(得分:1)
在Laravel 5.2
中,我们必须传递csrf
令牌来执行请求。
试试这样......
<script>
$('#brand_id').on('change',function(e){
console.log(e);
var brand_id = e.target.value;
//ajax
$.get('/product_id?brand_id =' + brand_id,{"_token":$("input[name='_token']").val()}, function(data));
//success data
$.each(data, function(upload_form, product_cat){
$('product_category').empty();
$('product_category').append('<option value="'+ product_cat.id +'">'+ product_cat.product_hierarchy +'</option>');
});
});
</script>
我只是将这行代码添加到您的获取请求中:
{ "_token" : $("input[name='_token']").val() }
祝你好运..快乐的编码!!!
