Jquery on Blur and on input conflict

I created a small AutoComplete object and list my results as a list of li elements. I have an this.on('input', function () {}); event that handles when you choose an item in the list and works fine. Now I want to add an blur event to hide results. Adding the blur events stops the input event from working.
$.fn.autoComplete = function () {
this.on('input', function () {
AutoComplete(self.val());
});
this.on('blur', function () {
$('#' + settings.resultsDivId).hide();
});
function AutoComplete(term) {
// ajax call
});
};

This worked in the following JSFiddle - it looks like you have an error after your AutoComplete function (it ends with ");"): https://jsfiddle.net/ek5v59t6/
$(function() {
$('input').autoComplete();
});
$.fn.autoComplete = function () {
this.on('input', function () {
console.log('input fired');
AutoComplete($(this).val());
});
this.on('blur', function () {
console.log('blur fired');
$('#results').hide();
});
function AutoComplete(term) {
$('#results').show();
}
};

Why is the jQuery on("click", "button", ...) running before the button is clicked?

I'm just learning jquery, and I'm running into behavior I don't understand. I have:
html:
<div id="tour" data-location="london">
<button>Get Photos</button>
<ul class="photos"></ul>
</div>
and
jquery:
var tour = {
init: function () {
$("#tour").on("click", "button", alert("clicked"));
}
};
$(document).ready(function () {
alert("hello");
tour.init();
});
The "hello" alert is appearing after the dom is loaded, as I would expect. However the "clicked" alert is firing as well, and does not subsequently fire when the button is pressed.
http://jsfiddle.net/abalter/295sgf5c/2/

If you want it to be executed when clicking on the button, you would need to wrap it in a function:
Updated Example
var tour = {
init: function () {
$("#tour").on("click", "button", function () {
alert("clicked")
});
}
};

See this fiddle.
Your callback needs to be a function, like this:
var tour = {
init: function () {
$("#tour").on("click", "button", function(e){alert("clicked")});
}
};

(document).ready is a global scope?

Guys i have this function inside my script.js:
$(document).ready(function() {
function alert() {
alert('AAAAAAAA');
}
});
And i am trying to call here in my index.html:
$('.something').on('click', function() {
e.preventDefault();
alert();
});
But is showing my this error - alert is not defined.
But when i take off the document ready in the external script, the click handler will work. Why is that?
The document ready is creating a separate scope?

Using $(document).ready() creates a new function scope (note the function() after the .ready), so when you call
$(document).ready(function() {
function alert() {
alert('AAAAAAAA');
}
});
alert is only defined within the document.ready block. There are two ways to solve this issue:
Define the function outside of the document.ready block:
function customAlert() {
alert('AAAAAAAA');
}
Attach the function to the window object:
$(document).ready(function() {
window.customAlert = function() {
alert('AAAAAAAA');
};
});

Include the click event into the document.ready
Check it here http://jsfiddle.net/fbrcm45q/1/
$(document).ready(function() {
function showAlert() {
alert('AAAAAAAA');
}
$('.something').on('click', function(e) {
e.preventDefault();
showAlert();
});
});

First of all e.preventDefault is a function so you have to add braces at the end:
e.preventDefault()
Second alert is a function in javascrpt, so you need to rename your function to something else, for example:
$(document).ready(function() {
function special_alert() {
alert('AAAAAAAA');
}
});
and:
$('.something').on('click', function() {
e.preventDefault();
special_alert();
});

How to call javascript function from ScriptManager.RegisterStartupScript?

I have the following javascript code:
<script type="text/javascript" language="javascript">
$(document).ready(
function () {
// THIS IS FOR HIDE ALL DETAILS ROW
$(".SUBDIV table tr:not(:first-child)").not("tr tr").hide();
$(".SUBDIV .btncolexp").click(function () {
$(this).closest('tr').next('tr').toggle();
//this is for change img of btncolexp button
if ($(this).attr('class').toString() == "btncolexp collapse") {
$(this).addClass('expand');
$(this).removeClass('collapse');
}
else {
$(this).removeClass('expand');
$(this).addClass('collapse');
}
});
function expand_all() {
$(this).closest('tr').next('tr').toggle();
};
});
</script>
I want to call expand_all function via code-behind .
I know I can use something like this, but it does not work and I don't understand used parameters:
ScriptManager.RegisterStartupScript(Me, GetType(String), "Error", "expand_all();", True)
Can you help me?

Because you have your expand_all function defined within anonymous $.ready event context. Put your code outside and it should work.
function expand_all(){
alert('test B');
}
$(document).ready(
function () {
// this won't work
function expand_all() {
alert('test A');
};
});
// will show test B
expand_all();
check this:
http://jsfiddle.net/jrrymg0g/

Your method expand_all only exists within the scope of the function inside $(document).ready(...), in order for you to call it from ScriptManager.RegisterStartupScript it needs to be at the window level, simply move that function outside the $(document).ready(...)
<script type="text/javascript" language="javascript">
$(document).ready(
function () {
....
});
function expand_all() {
$(this).closest('tr').next('tr').toggle();
};
</script>

JS Jquery Namespace Calling Functions

Ok terrible title but I couldn't think of another description.
I have the following code:
jQuery( document ).ready( function( $ )
{
$.myNamespace = {
init: function()
{
$('.button').click(function() {
this.anotherFunction();
});
},
anotherFunction: function()
{
alert('insidefunction');
}
}
$.myNamespace.init();
});
As you can see I am trying to call anotherFunction from inside init and have there the two ways I tried but didn't work. So how am I able to call that function or is my concept wrong?

jQuery( document ).ready( function( $ )
{
$.myNamespace = {
init: function()
{
var a=this;
$('.button').click(function() {
a.anotherFunction();
});
},
anotherFunction: function()
{
alert('insidefunction');
}
}
$.myNamespace.init();
});
http://jsfiddle.net/ZpAtm/2/

Absolutely calling it within the click handler changes things, as this inside any jQuery event handler is set to the element that caused the event.
Instead, try using the following pattern:
jQuery(document).ready(function($) {
$.myNamespace = (function() {
function init() {
$('.button').click(function() {
anotherFunction();
});
}
function anotherFunction() {
alert('insidefunction');
}
// return an object with all the functions you want
// available publically as properties. Don't include
// any "private" functions.
return {
init: init,
anotherFunction: anotherFunction
};
})();
$.myNamespace.init();
});​
