I have the following:
<div class="tab-pane" id="message">
<textarea rows="4" cols="50" id="send_message" placeholder="Enter text ..."> </textarea>
<a href="#message" class="btn btn-large btn-info" data-toggle="tab">OK</a>
<a href="#message" class="btn btn-large btn-info" data-toggle="tab">Cancel</a>
</div>
I want to clear the textarea contents when I click the cancel button. I have:
$('#message').on("click", "a", function(){
if($(this).is(":contains(Cancel)")) {
$("#send_message")(
function(){
$(this).val('');
}
);
}
else if($(this).is(":contains(OK)")) {
......
}
});
but this doesn't do anything. How can I fix this.
You can use this:
$('#message').on("click", "a", function () {
if ($(this).is(":contains(Cancel)")) {
$("#send_message").val('');
} else if ($(this).is(":contains(OK)")) { // other code
}
});
In your code you used the selector $("#send_message")
, you cannot just add a function
after that way.The $(this)
you referred in that "wrong placed" function you already "have" by using the id selector. So I used your idea and corrected some things on your code to make it work.
I think there is a bug in your line. It should just be:
$("#send_message").val("")
Here is a fiddle that does what you need. http://jsfiddle.net/PsWHJ/
<div class="tab-pane" id="message">
<textarea rows="4" cols="50" id="send_message" placeholder="Enter text ..."> </textarea>
<a href="#message" class="btn btn-large btn-info" data-toggle="tab">OK</a>
<a href="#message" class="btn btn-large btn-info" data-toggle="tab">Cancel</a>
</div>
$('a','#message').on('click',function(){
if($(this).text() === 'OK'){
alert('Process Form');
}else{
$('#send_message').val("");
}
});
There is another way...
$('#message').on("click", "a", function () {
var jqEl = $(this);
if (jqEl.text() == "Cancel")) {
jqEl.prevAll('textarea').val('');
} else if (jqEl.text() == "OK") {
//Do other stuff...
}
});
Hope it helps
