jquery日期选择器中的字体真棒图标

Question

I am trying to display the fontawesome icon on "buttonText" of jquery date picker but it displays the text and not the icon. Is it correct? I am using jquery 13.

$("#btnDate").datepicker({
            showOn: "button",
            buttonText: "<i class='fa fa-calendar'></i>",
            onSelect: function (selected) {
            }
        });

Answer 1

You could add the icon after setting the datepicker :

 $("#btnDate").datepicker({ showOn: 'button', buttonText: "", }).next('button').append('<i class="fa fa-calendar"></i>');

Answer 2

Datepicker created an element:

<img class="ui-datepicker-trigger" />

When you define the Text, it is added to the alt and title attributes. Like so:

<img class="ui-datepicker-trigger" src="images/calendar.gif" alt="Select date" title="Select date">

This is why your attempt is not working.

A click event is assigned to this that opens the datepicker. Since it's an image, you can't simply assign a Font Awesome Class to it.

Consider the following.

 $(function() { $("#datepicker").datepicker({ showOn: "button", buttonImageOnly: true, buttonText: "Select date" }); var newButton = $("<span>", { class: "ui-datepicker-trigger fa fa-calendar" }).click(function() { $(this).toggleClass("closed"); if ($(this).hasClass("closed")) { $("#datepicker").datepicker("show"); } else { $("#datepicker").datepicker("hide"); } }); $("img.ui-datepicker-trigger").replaceWith(newButton); });

Using .replaceWith() will do what you need to have done. It will not copy the event , so we have to recreate it.
