jQuery: enabling/disabling datepicker
提问by A K
In my php-file, I want to use the jQuery Datepicker.
在我的 php 文件中，我想使用 jQuery Datepicker。
When my file loads, I create the Datepicker disabled.
当我的文件加载时，我创建了禁用的 Datepicker。
Then, when a special field in my php-file (it is a form) is filled, I want to enable the Datepicker.
然后，当我的 php 文件（它是一个表单）中的一个特殊字段被填充时，我想启用 Datepicker。
So, initially my Datepicker looks like this:
所以，最初我的 Datepicker 看起来像这样：
$("#from").datepicker({
showOn: "both",
buttonImage: "calendar.gif",
buttonImageOnly: true,
buttonText: "Kalender",
showAnim: "drop",
dateFormat: "dd.mm.yy",
changeMonth: true,
changeYear: true,
showButtonPanel: true,
showWeek: true,
firstDay: 1,
dayNamesMin: ["So", "Mo", "Di", "Mi", "Do", "Fr", "Sa"],
weekHeader: "KW",
disabled: true,
onClose: function(selectedDate) {
$("#to").datepicker("option", "minDate", selectedDate);
}
});
This works just fine, no problem so far. The problem comes, when I want to disable the field.
这工作得很好，到目前为止没有问题。问题来了，当我想禁用该字段时。
If a special field is filled, I call $("#from").datepicker('enable');
如果填写了特殊字段，我会打电话 $("#from").datepicker('enable');
This also works fine, BUT now I want to disable it again if the special field I mentioned it empty again.
这也可以正常工作，但现在我想再次禁用它，如果我提到的特殊字段再次为空。
Then I use $("#from").datepicker('disable');and the field itself is grayed, but I can still use the field to enter values, the calender pops up and even the calender-image next to the box is clickable.
然后我使用$("#from").datepicker('disable');，字段本身变灰，但我仍然可以使用该字段输入值，日历弹出，甚至框旁边的日历图像也是可点击的。
Anyone has an idea why this is the case? Am I missing something?
任何人都知道为什么会这样？我错过了什么吗？

$("#from").datepicker('disable');should work, but you can also try this:
$("#from").datepicker('disable');应该可以，但你也可以试试这个：
$( "#from" ).datepicker( "option", "disabled", true );

Also set the field to disabled when you disable the datePicker e.g
当您禁用 datePicker 例如时，还将该字段设置为禁用
$("input").prop('disabled', true);
To stop the image being clickable you could unbind the click event on that
要停止图像可点击，您可以取消绑定点击事件
$('img#<id or class ref>').unbind('click');

This works for me on toggling enable and disable datepicker of JQuery:
这对我来说在切换启用和禁用 JQuery 的日期选择器时有效：
if (condition) {
$('#ElementID').datepicker(); //Enable datepicker
} else {
//Disable datepicker without the ability to enter any character on text input
$('#ElementID').datepicker('destroy');
$('#ElementID').attr('readonly', true); }
I don't know why but when I use enable/disablein datepicker options, it doesn't behave the way it should be. It only works after you enable and disable it, but once you disable it, it doesn't enable again after, so the code above works perfectly fine for me:
我不知道为什么，但是当我在 datepicker 选项中使用启用/禁用时，它的行为不应该是这样。它仅在您启用和禁用它后才有效，但是一旦您禁用它，它就不会再次启用，因此上面的代码对我来说非常好：
if (condition) {
$('#ElementID').datepicker('enable'); //Enable datepicker
} else {
//Disable datepicker but I cannot enable it again once it goes through this condition
$('#ElementID').datepicker('disable'); }

Datepicker is disabled automatically when the input text field is made disabled or readOnly:
当输入文本字段被禁用或只读时，日期选择器会自动禁用：
$j("#" + CSS.escape("${status.expression}")).datepicker({
showOn: "both",
buttonImageOnly: true,
buttonImage: "<c:url value="/static/js/jquery/1.12.1/images/calendar.gif"/>",
dateFormat: "yymmdd",
beforeShow: function(o, o2) {
var ret = $j("#" + CSS.escape("${status.expression}")).prop("disabled")
|| $j("#" + CSS.escape("${status.expression}")).prop("readOnly");
if (ret){
return false;
}
return o2;
}
});
