This example builds upon the <a href="events.html">Events</a> example, by demonstrating how you can use the select event to set the state of a text box on the page.

<p>It also demonstates how to limit the dates which can be selected using the mindate/maxdate properties and how the current page and selected date can be set on the Calendar after it is first rendered.</p>

<h2 class="first">Setting up the Calendar</h2>
|
|
|
|
<p>In this example, we will build a Calendar that can accept selections on any date from 1/1/2006 to 12/31/2008, and we will set up a text field that will be updated whenever the Calendar's selected date is changed. In addition, we will provide a button that can be used to update the Calendar with whatever date the user types into a text field provided on the page.</p>
|
|
<p>First, we will construct the Calendar with the minimum and maximum dates specified:</p>
|
|
|
|
<textarea name="code" class="JScript" cols="60" rows="1">
|
|
YAHOO.example.calendar.cal1 = new YAHOO.widget.Calendar("cal1","cal1Container",
|
|
{ mindate:"1/1/2006",
|
|
maxdate:"12/31/2008" });
|
|
</textarea>
|
|
|
|
<p>Next, we will place our markup, which includes a standard container for the Calendar, and the form with a text field and button:</p>
|
|
|
|
<textarea name="code" class="HTML" cols="60" rows="1">
|
|
<div id="cal1Container"></div>
|
|
|
|
<form name="dates">
|
|
<input type="text" name="date1" id="date1" />
|
|
<button type="button" id="update">< Update Calendar</button>
|
|
</form>
|
|
</textarea>
|
|
|
|
<p>Now, we must define a handler that will fire when the user changes the selected date on the Calendar. This function will be named <em>handleSelect</em>, and will be subscribed to the Calendar's <em>selectEvent</em>:</p>
|
|
|
|
<textarea name="code" class="JScript" cols="60" rows="1">
|
|
function handleSelect(type,args,obj) {
|
|
var dates = args[0];
|
|
var date = dates[0];
|
|
var year = date[0], month = date[1], day = date[2];
|
|
|
|
var txtDate1 = document.getElementById("date1");
|
|
txtDate1.value = month + "/" + day + "/" + year;
|
|
}
|
|
|
|
YAHOO.example.calendar.cal1.selectEvent.subscribe(handleSelect, YAHOO.example.calendar.cal1, true);
|
|
</textarea>
|
|
|
|
<p>The <em>handleSelect</em> function receives an array of selected dates as an argument. Since this Calendar is only single-select, we will only need to retrieve the first (and only) item in the array. The date argument is passed as an easily sorted Integer array in the format: [yyyy, mm, dd]. The <em>handleSelect</em> function takes these values and prints them into a text field which we will define in a later step. It's also necessary to subscribe the function to the <em>selectEvent</em> on the Calendar so that it will be fired when a selection is made.</p>
|
|
|
|
<p>
|
|
Next, we will define a function called <em>updateCal</em>, which will be used to update the Calendar with the value that is typed into the text field. This function will be called via a button that will be created in our markup a little later.
|
|
</p>
|
|
<p>
|
|
Note that on <em>line 7</em> we test whether or not any dates are actually selected after calling the select() method, since the date the user is trying to select may lie outside the min/max dates defined for the Calendar in which case the Calendar's selected date will not be changed (and a selectEvent will not be fired).
|
|
</p>
|
|
|
|
<textarea name="code" class="JScript" cols="60" rows="1">
|
|
function updateCal() {
|
|
var txtDate1 = document.getElementById("date1");
|
|
|
|
if (txtDate1.value != "") {
|
|
YAHOO.example.calendar.cal1.select(txtDate1.value);
|
|
var selectedDates = YAHOO.example.calendar.cal1.getSelectedDates();
|
|
if (selectedDates.length > 0) {
|
|
var firstDate = selectedDates[0];
|
|
YAHOO.example.calendar.cal1.cfg.setProperty("pagedate", (firstDate.getMonth()+1) + "/" + firstDate.getFullYear());
|
|
YAHOO.example.calendar.cal1.render();
|
|
} else {
|
|
alert("Cannot select a date before 1/1/2006 or after 12/31/2008");
|
|
}
|
|
|
|
}
|
|
}
|
|
</textarea>
|
|
|
|
<p>The <em>updateCal</em> function does two key things. First, it grabs the value from the text field and uses it to make a new selection on the Calendar. Next, it changes the visible page of the Calendar to the Calendar's earliest selected date, so that the selection will be clear to the user.</p>
