Jquery-ui 数据采集器更改 z-index

小开

最佳答案

Your JS code in the question doesn't work because jQuery resets the style attribute of the datepicker widget every time you call it.

An easy way to override its style's z-index is with a !important CSS rule as already mentioned in another answer. Yet another answer suggests setting position: relative; and z-index on the input element itself which will be automatically copied over to the Datepicker widget.

But, as requested, if for whatever reason you really need to set it dynamically, adding more unnecessary code and processing to your page, you can try this:

$('.date_field').datepicker({
//comment the beforeShow handler if you want to see the ugly overlay
beforeShow: function() {
setTimeout(function(){
$('.ui-datepicker').css('z-index', 99999999999999);
}, 0);
}
});

I created a deferred function object to set the z-index of the widget, after it gets reset'ed by the jQuery UI, every time you call it. It should suffice your needs.

The CSS hack is far less ugly IMO, I reserve a space in my CSS only for jQuery UI tweaks (that's right above the IE6 tweaks in my pages).

There is a more elegant way to do it. Add this CSS:

.date_field {position: relative; z-index:100;}

jQuery will set the calendar's z-index to 101 (one more than the corresponding element). The position field must be absolute, relative or fixed. jQuery searches for the first element's parent, which is absolute/relative/fixed, and takes its' z-index

The datepicker now sets the popup z-index to one more than its associated field, to keep it in front of that field, even if that field is itself in a popup dialog. By default the z-index is 0, so datepicker ends up with 1. Is there a case where this is not showing the datepicker properly? JQuery Forum Post

To get a z-index of 100. You need an input with z-index:99; and JQueryUI will update the datepicker to be z-index:100

<input style="z-index:99;"> or <input class="high-z-index"> and css .high-z-index { z-index: 99; }

You can also specify the z-index to inherit which should inherit from your dialog box and cause jQueryUI to properly detect the z-index.

<input style="z-index:inherit;"> or <input class="inhert-z-index"> and css .inherit-z-index { z-index: inherit; }

You need to use !important clause to force the in-line z-index value using CSS.

.ui-datepicker{z-index: 99 !important};

This worked for me when I was trying to use datepicker in conjunction with a bootstrap modal:

$('input[id^="txtDate"]').datepicker();
$('input[id^="txtDate"]').on('focus', function (e) {
e.preventDefault();
$(this).datepicker('show');
$(this).datepicker('widget').css('z-index', 1051);
});

Of course, change the selector to fit your own need. I set the "z-index" to 1051 because the z-index for the bootstrap modal was set to 1050.

The BEST NATURAL way is to simply put the date-picker element on a "platform" that has a "relative" position and has a higher "z-index" than the element that is showing up above your control...

In my case nothing worked. I needed to add the z-index to the input type that has the datepicker.

<input type="text" class="datepicker form-control" datatype="date" style="z-index: 10000;" id="txtModalDate">

This is for Bootstrap datetimepicker

If your datepicker is hiding because of scroll appears in your div use:

overflow-x: visible !important;
overflow-y: visible !important;

in css of whole div that contain your datepicker and other item such as

.dialogModel{
overflow-x: visible !important;
overflow-y: visible !important;
}

Add this:

    $(document).ready(function()
{
$('#datepickers-container').css('z-index', 999999999);
};
