当日期选择器的值更改时调用一个函数 [英] Call a function when values of the date picker changes
问题描述
我保留会话变量以将日期存储在我的网站中.如:
I am keeping session variables to store dates in my website. Such as:
<php $_SESSION['checkin'];
$_SESSION['checkout']; ?>
但是当有人更改日期选择器的日期时,应根据所选值修改会话变量值.我试图使用ajax调用来设置变量.这是上述任务的HTML代码和javascript函数.
But when someone changed the dates of the date picker, session variable values should be modified according to the selected values. I was trying to use an ajax call to set variables.This is the HTML code and the javascript function for the above-mentioned task.
HTML代码
HTML Code
<div id="reportrange" class="selectbox " style="border: 1px solid #ddd; border-radius: 4px; padding:5px; background: #fff; cursor: pointer; margin: 0 0 4px 0;overflow: hidden; white-space: nowrap;">
<i class="glyphicon glyphicon-calendar fa fa-calendar"></i>
<input type="hidden" onchange="changeSession()" name="selectdaterange" id="selectdaterange" value="<?php echo $_SESSION['checkin'] ?> - <?php echo $_SESSION['checkout']?>" disabled/>
</div>
JAVASCRIPT代码
JAVASCRIPT Code
<script type="text/javascript">
$(function() {
alert("dhgfhgfhf");
// var start = moment().add(1, 'days');
// var end = moment().add(2, 'days');
var start = moment('<?php echo $_SESSION['
checkin '] ?>', 'MM/DD/YYYY');
var end = moment('<?php echo $_SESSION['
checkout '] ?>', 'MM/DD/YYYY');
var min_date = moment().add(1, 'days');
function cb(start, end) {
$('#selectdaterange').val(start.format('MM/DD/YYYY') + ' - ' + end.format('MM/DD/YYYY'));
$('#reportrange span').html(start.format('MMMM D, YYYY') + ' - ' + end.format('MMMM D, YYYY'));
// changeSession(); // alert (start.format('MMMM D, YYYY') + ' - ' + end.format('MMMM D, YYYY'));
}
$('#reportrange').daterangepicker({
"autoApply": true,
"startDate": start,
"endDate": end,
"minDate": min_date,
"opens": "center"
}, cb);
cb(start, end);
});
function changeSession() {
alert("gfgf");
var start = document.getElementsByName('daterangepicker_start').value;
var end = document.getElementsByName('daterangepicker_end').value;
$.ajax({
type: 'POST',
data: 'checkin=' + start + '&checkout=' + end,
url: "<?php echo base_url(); ?>index.php/DateController/setHotelPageDate",
dataType: 'json',
cache: false,
success: function(response) {
alert("response.message");
}
});
}
</script>
但是不幸的是,我尝试使用 在变更事件上.但这不起作用.如果真的很感谢 有人可以帮助我.
But unfortunately, I tried to call this sessionChange() function using on change event. But it's not working. It would be really grateful if someone could help me with this.
推荐答案
如果您使用的是jQuery,建议您一路使用它.使用.change()
捕获更改事件.从输入元素中删除onchange=
.
If you are using jQuery, I suggest you use it all the way. Use .change()
to catch the change event. Remove the onchange=
from the input element.
$(document).ready(function() {
$("#selectdaterange").change(function changeSession() {
alert("gfgf");
var start = document.getElementsByName('daterangepicker_start').value;
var end = document.getElementsByName('daterangepicker_end').value;
$.ajax({
type: 'POST',
data: 'checkin=' + start + '&checkout=' + end,
url: "<?php echo base_url(); ?>index.php/DateController/setHotelPageDate",
dataType: 'json',
cache: false,
success: function(response) {
alert("response.message");
}
});
});
});
还请注意,更改事件仅在模糊发生后才会触发.
Also note that change event will only fire after blur happens.
