How to send data without refreshing page in laravel?
提问by Hemanth
I need send data to the database without refreshing page.
我需要在不刷新页面的情况下将数据发送到数据库。
Home Blade :
家庭刀片：
<form class="chat" id="message" action="#" method="post">
<input type="hidden" name="_token" id="_token" value="{{ csrf_token() }}">
<li>
<div class="panel-footer">
<div class="input-group">
<input type="text" name="message" class="" placeholder="Type your message here..." />
<span class="input-group-btn">
<button type="submit" class=" btn-success btn-sm searchButton" id="save" >
Send
</button>
</span>
</div>
</div>
</li>
</form>
Controller :
控制器 ：
public function message(Request $data)
{
$ins = $data->all();
unset($ins['_token']);
$store = DB::table("chatbox")->insert([$ins]);
return Redirect('Users/home')->with('message',"success");
}
Ajax :
阿贾克斯：
<script>
$(document).on("click", ".save", function() {
$.ajax({
type: "post",
url: '/Users/message',
data: $(".message").serialize(),
success: function(store) {
},
error: function() {
}
});
});
</script>
At present when I send data it is automatically refreshing the whole page but only the particular form need to be refreshed.
目前，当我发送数据时，它会自动刷新整个页面，但只需要刷新特定的表单。

You should change the type of the button from submitto buttonlike :
您应该将按钮的类型从更改submit为buttonlike ：
<button type="button" class=" btn-success btn-sm searchButton" id="save" >end</button>
Or prevent the default action (submit) using e.preventDefault();like :
或者submit使用e.preventDefault();like阻止默认操作 ( ) ：
$(document).on("click",".save",function(){
e.preventDefault(); //Prevent page from submiting
...
...
});
NOTE :Note also that you don't have button with class savebut with id saveso the event handler should looks like :
注意：另请注意，您没有带 classsave但带 id 的按钮，save因此事件处理程序应如下所示：
$(document).on("click", "#save", function(){

You have to handle function inside javascript/jquery form submitfuntion and use e.preventDefault()to stop HTML to submit the form.
您必须在 javascript/jquery 表单submit功能中处理函数并使用e.preventDefault()停止 HTML 来提交表单。
Try your ajax code in the below code type.
在下面的代码类型中尝试您的 ajax 代码。
$('#message').submit(function(e) {
e.preventDefault();
//your ajax funtion here
});
You can reset/refresh your form in success function
您可以在成功功能中重置/刷新表单
$("#message").trigger("reset");

You need to prevent the default form submission, and use the script instead
您需要阻止默认表单提交，并使用脚本代替
$(document).on("click", "#save", function(e) {
e.preventDefault(); // Prevent Default form Submission
$.ajax({
type:"post",
url: '/Users/message',
data: $("#message").serialize(),
success:function(store) {
location.href = store;
},
error:function() {
}
});
});
and instead of returning a redirect, return the url from the controller and let the script handle the redirect
并且不返回重定向，而是从控制器返回 url 并让脚本处理重定向
public function message(Request $data)
{
$ins = $data->all();
unset($ins['_token']);
$store = DB::table("chatbox")->insert([$ins]);
session()->flash('message', 'success');
return url('Users/home');
}
回答by common sense
Remove return Redirect('Users/home')->with('message',"success");and just return an array like
删除return Redirect('Users/home')->with('message',"success");并返回一个数组，如
return ['message' => 'success'];
