How to pass parameters in Impromptu callback?
I'm using jQuery Impromptu as a pop window. The raw code is as follow:
function f1(pa1, pa2){
$.prompt("need to开发者_StackOverflow中文版 delete?",{
callback: callbackfunc,
button: {OK: true, Cancel: false}
});
}
function callbackfunc(v,m,f){
if(v){
// want to process the pa1 and pa2.
}
}
How to process pa1 and pa2 inside the callback?
I use what you want in a project. See this:
function removePhoto(id){
var txt = 'Are you sure you want to remove this photo?<input type="hidden" id="photoid" name="photoid" value="'+ id +'" />';
$.prompt(txt,{
buttons:{Delete:true, Cancel:false},
callback: function(v,m,f){
if(v){
var pid = f.photoid;
//Here is where you would do an ajax post to remove the user
//also you might want to print out true/false from your .php
//file and verify it has been removed before removing from the
//html. if false dont remove, $promt() the error.
$.get('<?php echo base_url(); ?>index.php/ajaxed/del_photo/'+pid, function(data){
if(data != 'false'){
$.prompt('The photo was successfuly deleted...', { callback: function() {
photosEdit--;
if(photosEdit == 0) {
window.location = "<?php echo base_url(); ?>index.php<?php echo ($row_p->aid == 0 ? "/gallery/view/me" : "albums/view/".$this->dx_auth->get_user_id()."/".$row_p->aid); ?>";
} else {
$("div#editWrapper_"+pid).hide("slow", function() { $(this).remove();});
}
} });
//recirect history-1
}else{ $.prompt('An error occured while removing this photo...'); }
});
}
else{}
}
});
}
I solve my problem like this:
function f1(pa1, pa2){
$.prompt("need to delete?",{
callback: function(v, m, f){
if(v){
// process of pa1, pa2...
}
},
button: {OK: true, Cancel: false}
});
}
It's OK if there is less parameters to process. however, if the callback function is too complex, and there are much parameters, this method is a not good.
I hope somebody could give me a better suggestion.
If your code on the callback method is getting complex, the best way to do this is:
var g_pa1,g_pa2; // General variables
function f1(pa1, pa2){
g_pa1 = pa1;
g_pa2 = pa2;
$.prompt("need to delete?",{
callback: callbackfunc,
button: {OK: true, Cancel: false}
});
}
function callbackfunc(v,m,f){
if(v){
//PROCESS YOUR g_pa1 and g_pa2
g_pa1 = null;
g_pa2 = null;
}
}
I'm not sure if the plugin changed this or there was a wrong documentation somewhere, but the callback is submit nowadays and it takes 4 arguments instead of 3: event, value, message, formVals:
buttons: { Cancel: false, Next: true },
submit:function(e,v,m,f){ }
Adapting @Oytun Tez excelent answer, I've made this example:
<html>
<head>
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="impromptu.js"></script>
<link rel="stylesheet" media="all" type="text/css" href="impromptu.css" />
<script type="text/javascript">
function removePhoto( id )
{
var txt = 'Are you sure you want to remove this photo?<input type="hidden" id="photoid" name="photoid" value="'+ id +'" />';
$.prompt( txt,
{
title: "Remove Photo",
buttons:{ Delete:true, Cancel:false },
submit: function( event, value, message, formVals )
{
if( value )
{
var pid = formVals.photoid;
console.log('pid: ' + pid );
}
}
});
}
$(document).ready( function()
{
$('.btn').on('click', function( e )
{
removePhoto( $(this).data('id') );
});
});
</script>
</head>
<body>
<input class="btn" type="button" value="Remove photo 1" data-id="1" />
<input class="btn" type="button" value="Remove photo 2" data-id="2" />
</body>
</html>
