Sending url using ajax on codeigniter - ajax

Question

I have this Ajax script where I pass a link to the data variable link, but I
get a 412 error.
$(function() {
$(".check-multi").change(function() {
$.ajax({
type: "POST",
url: "<?php echo site_url('adm/updateproperty'); ?>",
async: true,
data: {
link: $(this).data('link')
},
success: function(msg) {
alert('Success');
if (msg != 'success') {
alert('Fail');
}
}
});
});
});
I have tried
link: encodeURI($(this).data('link'))
And
link: encodeURIComponent($(this).data('link'))
as is suggested on other threads but I still get the 412 error message.

Answer 1

Hope this will help you :
you have added newline character to json data that is why you got error
Do like this :
var link = $(this).data('link');
data: {"link" : link},
/*----OR do this -----*/
data: {"link" : $(this).data('link')},
instead of this :
data: {
link: $(this).data('link')
},
Whole code should be like this :
var link = $(this).data('link');
/*console.log(link)*/
$.ajax({
type: "POST",
url: "<?php echo site_url('adm/updateproperty'); ?>",
async: true,
data: {"link" : link },
success: function(msg) {
alert('Success');
if (msg != 'success') {
alert('Fail');
}
}
});

Please change your code in data options. Use this way
data: {"id": ID},
i.e. store the value in a variable and send that variable in data option. If we assume
ID=$(this).data('link');`
Then the code will be as follows:
$(function() {
$(".check-multi").change(function() {
$.ajax({
type: "POST",
url: "<?php echo site_url('adm/updateproperty'); ?>",
async: true,
data: {"id":ID},
success: function(msg) {
alert('Success');
if (msg != 'success') {
alert('Fail');
}
}
});
});
});
Please check it.
