Laravel 4 restful delete a record with a resource controller
提问by Christopher Kikoti
I am new to Laravel framework but I really like it. My biggest problem is I have been searching on how I can delete a single record using resource controller.
我是 Laravel 框架的新手，但我真的很喜欢它。我最大的问题是我一直在寻找如何使用资源控制器删除单个记录。
Controller method:
控制器方法：
public function destroy($id) {
$department = Department::find($id);
$department->delete();
}
Delete link I have tried:
删除我尝试过的链接：
<a class="btn btn-xs btn-danger" data-method="delete" href="{{ URL::to('department/' . $department->id) }}"><i class="icon-remove"></i></a>
Javascript:
Javascript：
<script type="text/javascript">
$(function(){
$('[data-method]').append(function(){
return "\n" +
"form action='" + $(this).attr('href') + "' method='post' style='display: none;'>\n" +
"<input type='hidden' name='_method' value='"+$(this).attr('data-method')+"'>\n" +
"</form>\n"
})
.removeAttr('href')
.attr('style', 'cursor: pointer;')
.attr('onclick', '$(this).find("form").submit();');
});
Now when I click on the delete link, it doesn't work. Any idea on what am I doing wrong, I have been searching for so long.
现在当我点击删除链接时，它不起作用。关于我做错了什么的任何想法，我一直在寻找这么长时间。

Use $.post()to trigger your click instead of that form creation/submission:
使用$.post()触发您的点击而不是该表单创建/提交：
$(document).on("click", "[data-method]", function(e) {
e.preventDefault();
$.post($(this).attr('href'), {/* the id goes here */});
});
Apply the cursor style via CSS. I must admit that I'm not sure if laravel expects a HTTP DELETE instead of a post. And I think you missed to submit the id of the department you want to delete.
通过 CSS 应用光标样式。我必须承认，我不确定 laravel 是否需要 HTTP DELETE 而不是 post。而且我认为您错过了提交要删除的部门的 ID。
[edit] As laravel expects a HTTP DELETE you can't use the $.post() shorthand, but $.ajax()instead:
[编辑] 因为 laravel 需要一个 HTTP DELETE 你不能使用 $.post() 简写，而是使用$.ajax()代替：
$(document).on("click", "[data-method]", function(e) {
e.preventDefault();
$.ajax({
url: $(this).attr('href'),
type: "DELETE",
data: {/* the id goes here */},
success: function(data, textStatus, jqXHR) {
console.log("success");
}
});
});

The destroy()will be called in DELETErequest and not in POSTrequest.
在destroy()将被调用的DELETE请求，而不是POST请求。
So try ,
所以尝试，
<a class="btn btn-xs btn-danger" onclick="deleteDepartment($department->id)" href="javascript:void(0)"><i class="icon-remove"></i></a>
And in javascript,
在 JavaScript 中，
function deleteDepartment(id) {
$.ajax({
url: 'department/'+id,
type: 'DELETE',
success: function(result) {
// Do something with the result
}
});
}

Thanks for the answers guys, it works just as it is I just forgot the opening < when creating a form ie I was mistakenly wrote:
感谢您的回答，它的工作原理就像我在创建表单时忘记了开头 < 即我错误地写道：
"form action='" + $(this).attr('href') + "' method='post' style='display: none;'>\n" +
Instead of:
代替：
"<form action='" + $(this).attr('href') + "' method='post' style='display: none;'>\n" +
