如何检查在php中点击的按钮的ID
I have 2 buttons "removeD" and "updateRecord"(by id) and I have written same ajax for them as follows:
$.ajax({
url: 'DB/tableDisplay.php',
type: 'POST',
data: 'id='+uid,
dataType: 'html'
})
But in tableDisplay.php I want to have different functionality for both the buttons.How to check the id of the button clicked in php?
I've tried using :
if(isset($_POST['removeD'])){
}else{
}
But this is not working.
我有2个按钮 但是在tableDisplay.php我 想要为这两个按钮提供不同的功能。如何查看在php中点击的按钮的ID？
我尝试过使用：
“removeD” code>和“updateRecord” code >（按id）我已经为它们编写了相同的ajax，如下所示： p>
$ .ajax（{
url：'DB / tableDisplay.php'，
type ：'POST'，
data：'id ='+ uid，
dataType：'html'
}）
code> pre>
if（isset（$ _ POST ['removeD']））{
} else {
} code>
但这不起作用。 p> \ n div>
$('body').on('click','#id1',function(){
$.ajax({
url : 'url',
data : {variable:values},
type : 'html',
dataType : 'GET/POST',
success : function(data){
console.log('Message after Success');
},
error : function(){
console.log('Error Message')
}
});
});
In your url page you can find whether ajax request is posted or not
if(isset($_REQUEST['variable'])){
write your php code here........
}
Try the following code to detect the button clicked:
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function () {
$('.click-button').on('click',function () {
var button_id = $(this).attr('id');
if(button_id == 'removeD'){
alert('removeD button clicked');
}else if(button_id == 'updateRecord'){
alert('updateRecord button clicked');
}
});
});
</script>
</head>
<input type="button" class="click-button" id="removeD" value="removeD">
<input type="button" class="click-button" id="updateRecord" value="updateRecord">
Try this:
$(document).ready(function(){
$('button').click(function(){
var id = $(this).attr('id');
$.ajax({
url: 'DB/tableDisplay.php',
type: 'POST',
data: {id: id},
dataType: 'html'
})
});
});
You can use target it return which DOM element triggered the event. see below code its too easy and short to get id of clicked element.
$('button').click(function(e){
alert(e.target.id);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="remove">Remove</button><br>
<button id="update">Update</button><br></div>
