Jquery datepicker更改事件触发器和输入的默认更改事件
问题描述：
我有datepicker
I have datepicker
<input type='text' class='inp'>
<script>
$('.inp').datepicker();
$(".inp").on("change",function (){
console.log('inp changed');
}
</script>
当我第一次更改.inp手动输入一个值，然后我点击datepicker的打开的日历我得到两个'更改'事件侦听器首先从手动更改，然后从datepicker更改
我如何避免这个？谢谢！
When I first change .inp manually type there a value, then immidiately I click on datepicker's opened calendar. I get two 'change' event listeners. First from manual change, then from datepicker change. How can I avoid this? Thanks!
答
设置您的输入 readOnly ，它将帮助您仅通过图标更改字段的值。
Set your input readOnly, it will help you to change the value of field through icon only.
<input type='text' class='inp' readOnly />
然后使用 onSelect 来获取选定的日期，如下所示：
then use onSelect to get selected date, as following:
$(function() {
$(".inp").datepicker({
onSelect: function(dateText, inst) {
// alert(dateText);
}
});
});
