how will i take this javascript variable var textBoxVal = $(this).val() in my controller function.
controller:
public function selectallbudget(){
$mydate= $this->input->post('val');
$sendMe = $this->money_m->selectbudget($mydate);
echo json_encode($sendMe);
}
With the help of ajax you can do it.
FIRST: -------------------------------- <!--write this code in you header--> <input type="hidden" value="<?php echo base_url(); ?>" id="baseurl"/>
<!--your javascript code-->
<script type="text/javascript">
var base_url = $('#baseurl').val();
var dateValue = $('#mydate').val();
$.ajax({
url: base_url + "controller_name/function_name", // define here controller then function name
method: 'POST',
data: { date: dateValue }, // pass here your date variable into controller
success:function(result) {
alert(result); // alert your date variable value here
}
});
</script>
<!--your controller function-->
public function budget()
{
$dat = $_POST['date'];
echo $dat;
}
--------------------------------
SECOND: if you want to load any html code then you use this method otherwise above first method
--------------------------------
<!--write this code in you header-->
<input type="hidden" value="<?php echo base_url(); ?>" id="baseurl"/>
<!--your javascript code-->
<script type="text/javascript">
var base_url = $('#baseurl').val();
var dateValue = $('#mydate').val();
$( "#mydate" ).load(
base_url + "controller_name/function_name", // define here controller then function name
{ date: dateValue }, // pass here your date variable into controller
function(){
// write code on success of load function
}
);
</script>
<!--your controller function-->
public function budget()
{
$dat = $_POST['date'];
echo $dat;
}
Your code is almost okay. There is only one change in your controller code:
Controller:
public function selectallbudget(){
//$mydate= $_POST['val']; This is not PHP this is codeigniter
$mydate = $this->input->post('val');
$sendMe = $this->money_m->selectbudget($mydate);
echo json_encode($sendMe);
}
Please make use of ajax. This problem has already been discussed here. Please refer it.
What you're doing wrong here is $(this).val()
to pass on the input's value.
The this
object's scope keeps on changing, and is quite different when you try to access in
data: {
val: $(this).val()
}
It's rather trying to access the current object at hand.
Solution's pretty simple though (since you're already initialising textBoxVal
to the input's value.
$('#mydate').on('click', function () {
var textBoxVal = $(this).val();
$.ajax({
type: 'POST',
url: '<?php echo base_url();?>Money_c/selectallbudget', // link to CI function
data: {
val: textBoxVal
},
success: function (msg) {
console.log(msg);
}
});
});
