JavaScript - My Rollover Images Have Spaces In Between Them And I Need Them To Touch...

I'd be grateful for any help please. I've just started to build my first ever sencha app and am pleased with the results so far, but am now stuck on one thing. I've built a search form and want to be able to display the results on the same page, but this is where I'm stuck. The form works and sends the results using GET, but it doesn't send it to the correct place. I want to show it on the same page (I've built a php file called search.php to handle the results), but it reloads the whole app with the variables in the url.

I've tested all of the code away from the app and it works perfectly so I know the problem isn't with the code, but more with my lack of understanding of Sencha so would be extremely grateful for any help.
Code:

searchForms = new Ext.TabPanel({
    fullscreen: true,
    title: 'Search',
    displayField: 'text',
    sto  searchForm,
    iconCls: 'search',  
    items: [{
        id: 'searchSubmit',
        xtype: 'form',
        standardSubmit : true,
        scroll: 'vertical',
        items: [{
            xtype: 'fieldset',
            title: 'Keywords',
            defaults: {
                // labelAlign: 'right'
                labelWidth: '35%'
            },
            items: [{
                xtype: 'textfield',
                name: 'keywords',
             id: 'keywords',
                placeHolder: 'EG: Music, TV',
                autoCapitalize : true,
                required: true,
                useClearIcon: true
            }]
        }, {
            xtype: 'fieldset',
            title: 'Advanced Search',
            items: [{
                    xtype: 'selectfield',
                name: 'genre',
             id: 'genre',
                label: 'Genre',
                options: [{
text: 'All',
value: ' '
text: 'Country',
value: '1'
text: 'Sci-Fi',
value: '2'
text: 'Western',
value: '3'
                }]
            }, {
                xtype: 'selectfield',
                name: 'media',
             id: 'media',
                label: 'Media',
                options: [{
text: 'All',
value: ' '
text: 'Music',
value: '1'
text: 'TV',
value: '2'
text: 'Movie',
value: '3'
                }]
            }]
        }, {
            layout: 'vbox',
            defaults: {xtype: 'button', flex: 1, style: 'margin: .5em;'},
            items: [{
                text: 'Search',
                 ui: 'confirm',
                scope: this,
                hasDisabled: false,
                handler: function(){
                    searchForms.submit({
                    url: 'search.php'
                });
                }
            }, {
                text: 'Reset',
                ui: 'decline',
                handler: function(){
                    searchForms.reset();
                }
            }]
        }]
    }]
});

I've then tried to use this to display the results on the same page, but as I say this just doesn't work. It doesn't call the search.php page at all.

I've made sure all of the files (except the index.js file which is in a js folder) are in the same directory as the index.html file.

I've also tried to load the file in the app seperately by using:

Code:

 
Ext.regModel('mobile', {
    fields: [
       {name: 'text',        type: 'string'}
    ]
});

var searchForm = new Ext.data.TreeStore({
    model: 'mobile',
    proxy: {
        type: 'ajax',
        url: 'search.php?keywords=test',
        reader: {
            type: 'tree',
            root: 'items'
        }
    }
});

and that works perfectly so I know that all of the php stuff is working and does work with Sencha Touch, but I'm just not sure how to get it to only work when somebody clicks 'search'

I'd be grateful for any help with this as I've spent days searching the web to get this fix, but nothing seems to be working

I don't know if this is of help, but the main javascript file is:

i am new to sencha touch,and i created a login form which accepts user id and password and a login button,so when i click on login button i should get the user id value as a alert.and the code is
Code:

Ext.setup ({
onReady: function () {

    var myform=new Ext.form.FormPanel({
    id:'form',
    fullscreen:true,
    standardSubmit:true,
    dockedItems:[{
    Dock:'top',
    xtype:'toolbar',
    height:40,
    title:'Tool Bar',
    id:'login',
    }
    ],
    items:[{
 xtype:'textfield',
 name:'id',

 width:'50%',
 align:'center',
 label:'User Id'
 },
 {
 xtype:'textfield',
 name:'pwd',
 id:'pwd',
 width:'50%',
 align:'center',
 label:'Password'
 },

 {
  xtype:'button',
  ui:'round',
  width:'50%',
  text:'Login',
  align:'center',
  handler:function()
  {
    gettingvalues();/* var fields = form.getValues();
    console.log(fields['name']); */

  }
 }
 ],

    });

    gettingvalues=function()
    {
      var fields=myform.getValues();
      Ext.Msg.alert(fields['id'].getValue()); 
    }


}
});

But am not getting any value in alert,what i have to do. and after that i want to send those values to our local server which requires id and password,it will be in the format of... oururl?action=login&id=xyz&pwd=xyz, in this it will accepts and returns the response,so for that what i have to write, please let me know as soon as possible. Thanks in advance.

Hi developers

Needing some help.

My javascript/css drop down menu is not working on the ipad or other touch screen devices. It works fine on laptops & desktops which use a mouse.

I've discovered that this is because touchscreen devices like the Ipad do not recognise the onmouseover/onmouseout event handler that my script relies on. Is there any way I can modify my script so that it is compatiable both with traditional devices and touchscreen devices?

The code I am using is:
<script type="text/javascript"><!--
var timeout = 500;
var closetimer = 0;
var ddmenuitem = 0;

// open hidden layer
function mopen(id)
{
// cancel close timer
mcancelclosetime();

// close old layer
if(ddmenuitem) ddmenuitem.style.visibility = 'hidden';

// get new layer and show it
ddmenuitem = document.getElementById(id);
ddmenuitem.style.visibility = 'visible';

}
// close showed layer
function mclose()
{
if(ddmenuitem) ddmenuitem.style.visibility = 'hidden';
}

// go close timer
function mclosetime()
{
closetimer = window.setTimeout(mclose, timeout);
}

// cancel close timer
function mcancelclosetime()
{
if(closetimer)
{
window.clearTimeout(closetimer);
closetimer = null;
}
}

// close layer when click-out
document.onclick = mclose;

//--></script>

Which drives the following html:

<ul id="links">

<li><a href="whats_new/whats_new.html">what's new</a></li>

<li><a href="#"

onmouseover="mopen('m1')"

onmouseout="mclosetime()">clothing</a>

<div id="m1"

onmouseover="mcancelclosetime()"

onmouseout="mclosetime()">

<a href="clothing/clothing_page1.html">clothing</a>

</div>

</li>

<li><a href="#"

onmouseover="mopen('m2')"

onmouseout="mclosetime()">accessories</a>

<div id="m2"

onmouseover="mcancelclosetime()"

onmouseout="mclosetime()">

<a href="bags/bags_page1.html">bags</a>

<a href="jewellery/jewellery_page1.html">jewellery</a>

</div>

</li>
</ul>

Any suggestions would be much appreciated.

Thank you.

Edit2:: This is what I got to work.
Code:

<INPUT class=touch type=button value='UP' onMouseDown="up=true;" onMouseUp="up=false;">
<INPUT class=touch type=button value='DOWN' onMouseDown="down=true;" onMouseUp="down=false;">

Then added a check to see if (up==true) {move up code}
else if (down==true) {move down code}
etc


Edit::

Basically Code:

<INPUT class=touch type=button value='38' onMouseDown="movingUP();">

Then in JS Code:

function movingUP(){
 window.event.keyCode = 38;
}

But what do I put in movingUP() to send keyCode 38 when while the button is being clicked?????????????????????





Trying to add 8 icons of W,A,S,D, LEFT, RIGHT, UP, DOWN which upon click/touch will input the relative command to the screen canvas for mobiles that don't have a keyboard.

They aren't clicking on the canvas. I need some buttons/icons/images outside the canvas probably in a div, that send input events as an alternative to a keyboard...Something that can be clicked and held down to repeatedly spam that key to walk in that direction.

I have script to click icons from a keyboard and output the clicked key to a text field, but I don't know how to tie it into my keyboard listener in my game..

My game code uses:
Code:

// Handle keyboard controls
var keysDown = {};
addEventListener("keydown", function (e) {
 keysDown[e.keyCode] = true;
}, false);
addEventListener("keyup", function (e) {
 delete keysDown[e.keyCode];
}, false);

Then elsewhere I can trigger events when keysDown contains the number of a key that triggers an item like:

Code:

if (38 in keysDown && hero.y > 0 ) { 	// Player holding UP key
 	//walk north code here
	}

Is there a simple way to click on a button and send the "UP" keyCode to the entire screen? Particularly the canvas element......Or get it into my keysDown[e.keyCode];


I found this: Quote:
function addKey(cKey)
{
d = document.forms["foo"].elements["bar"];
d.value = (cKey.value=='backspace') ? d.value.slice(0,-1) : d.value+cKey.value;
}

//elsewhere in html body
<INPUT class=touch type=button value=w onClick="addKey(this)">
which will send 'w' when clicked, and I tried to send '38' instead but it only sends it to 1 element and not the entire screen....so it shows 38 in a text box each time I click it but it doesn't actually send 38 to keys being pressed.

Is there a simple way to do this? I wanted to add a fire button and others I figured I could just put an image with an event but can't figure it out....

Hello all,
I've got a problem with a JS dropdown menu that I'm using. It's an unordered HTML list that is driven by a JS file.

The menu is at Watt You Need Electrical - Offering Electrical Services For Geelong, Bellarine Peninsula & The Surf Coast

Initially when I got the menu template all the top level items and all the list items were coded as links. What I've done is make the Electrical heading just text and the two dropdown list items below it are still links. The menu works both on a desktop with a pointer and also on a mobile device by touch. The problem is that on a mobile device when I touch the Electrical heading the dropdown doesn't appear. The Solar heading and the dropdown below it work fine because the Solar heading is still a link. Obviously I've created the problem by changing the Electrical heading to text from a link but I'd like to be able to have it that way.

I've tested using some online mobile device emulators and it works OK there but when I physically test on an Iphone 5 the bug is there. I haven't been able to get my hands on any other phones or devices to test yet so don't know if it's a problem just with Iphones or Ipads.

I've had a look through the Dropdown.src.js file but it's way beyond me, I've listed both the HTML and JS file below.

Code:

Hey guys,

Lookin' for a little help, not sure if it can even be done? hopefully someone has the answer.

I'm trying to design myself an online portfolio; here's what I got so far...

http://www.gregorymstevens.com/testsite/site.html

As you can see my navigation is represented by each bird on the tree (every bird is a link), when you rollver one of the green birds they turn white, however, I am looking to not only have the green bird rollver to white but ALSO have the "choose a" image on the bottom right change to the corresponding page.

For instance, when the mouse rolls over a bird-- this image:



will turn into this image:



while maintaining the original "white bird" rollover.



Hopefully I'm explaining this correctly -- Any help greatly appreciated!

So <br/> creates a brake but is there a way to make "tab" space?

Hey Guys,

I am a student doing my Cert IV in IT and am having a bit of trouble with some code. I have a form that when a letter is entered it returns a message saying you need to enter numbers in, and am trying to find a way of it checking if there are spaces in the numbers entered at the same time as checking if a number has been entered. My code looks as follows:

Code:

<html>
<head>
<title>Activity 2.25</title>

<script type="text/javascript">
function validateform()
{

	var iPodMoney;
	var CarPrice;
	var flag;
	flag="OK"
        
        element=document.getElementsByTagName('input');
        
        for(counter=0; counter<element.length; counter++)
        {
               switch (element[counter].type)
               {
                       case "submit":
                       break;
                       
                       default:
                               if(isNaN(element[counter].value))
                               {
                                      alert("You will need to enter a number into " + element[counter].name);
				      flag="NotOK"
                               }
					else
					{
						BikeMoney=element[0].value;
						TVMoney=element[1].value;
						iPodMoney=element[2].value;
						CarPrice=element[3].value;
					}
               }
               
        }

Hi All,

I have a form in my homepage which takes some values. In that, a text box takes multiple values seperated by spaces. I have allowed only alphanumeric characters in that with the following code.

Code:

function rmsplcharchkdepo()
{
var iChars = "\\\/~!@#$%^&*()=+[]{}|;:?,.\"`'<>";
var un= document.getElementById("deposit").value;
  for (var i = 0; i < document.ipmform.deposit.value.length; i++) {
        if (iChars.indexOf(document.ipmform.deposit.value.charAt(i)) != -1) {
        alert ("Error!! Remove Special Characters.");
        document.getElementById("deposit").value = un.substring(0,0);
        return false;
        }
}
}

How can i trim the multiple spaces entered by the user between values instead of one single space allowed..

For eg:

TEXTBOX:INDIA USA UK



User should not be able to enter a space at the beginning, multiple spaces between the values and at the end. This is just to avoid unwanted complications at the backend.

In brief i need a script which trim multiple and consecutive spaces to one.

It would be a great help if some one can help me in this.

hi all

i m using the following validation code to validate email id
Code:

if (!/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,4})+$/.test(document.getElementById("customer_name").value))
	 {
	msg=msg+"Must Enter a valid Login-id/Email\n";
	document.getElementById("customer_name").focus();
	}

now i need that if the email id contains white blank space in front of email id or end of email id then this validation should pass otherwise not.

at present if there is blank space in front and end of email id then the validation doesnt passes and gives alert.

what should i add in it to validate it or how can it automatically remove white spaces before validating.

Hi guys (and gals)

Working on my uni essay, and really struggling here with a resolution to this part of code. Maybe I shouldnt be looking for the answer, but more so on where I am going wrong.

What I am meant to do is replace the spaces in sString with the actual word 'space' i.e hello 'everyone' = 'hellospaceeveryone'

Any help would be appreciated!

Code:

function substituteSpaces(aString)
	{
		sRet = '';
		for (var iA = 0; iA < aString.length; iA++)
		{
		if (iA = 0)
			sRet = sRet + ' ';
			//sRet = sRet + 'space';
		//var nextLetter = aString.charAt(iA);		
		// sRet = sRet + nextLetter;
		}
	}	
	sSpace = substituteSpaces('a string with spaces');
	alert ("Hello");

Hi everyone,

I run a math site and I just recently built a little program to generate math problems. When the user submits the correct answer the program changes the problem and all the steps/hints. Everything works fine except that during the change over there are all these weird blocks (same color as my background) (*FireFox Only). It only lasts for a couple of seconds, but it would be nicer if it smoothly replaced the problem. Here is the test site:

http://www.rootmath.org/test/solving-limits
The program/practice problem is at the bottom, if you don't know how to solve it you can hit "hint" until it gives you the answer. When you enter the correct answer and then click for a new problem you'll see the funky blocks.


Any help/suggestions would be greatly appreciated! Here is the code:


writeProblem() is called when the user gets the right answer and asks for another problem:
Code:

var writeProblem = 	function(){

		//these are neccessary after the first call to writeProblem.
		$(".steps").hide();	
		$("#submit_answer").show();
		$("#next_problem").hide();
		showStep.reset();

		//CLEAR "steps_area"
		var problem_area = document.getElementById('steps_area');
		while(problem_area.firstChild){
			problem_area.removeChild(problem_area.firstChild);
			}
		
		//Create a limit problem
		var limit = limits();
		limit.setDenominator(rand(6,0));
		var denom = limit.getDenominator();
		var randInt = 0//rand(3,0);
		var lim = limit.getType(randInt, denom);
		var step = lim.step(denom);
		answer = lim.getAnswer(); 	 //made global so checkAnswer() can access it
		var x = document.getElementById('problem');
		x.innerHTML = addLatex(lim.problem);
		
		var problem_area = document.getElementById('steps_area');
		//loop over array of steps and print them to steps div
		var length = step.length;
		for(var i=0; i<length; i++){
			var divTag = document.createElement("div");
			divTag.id = "step" + i;
			divTag.className = "steps"; 
			divTag.innerHTML = step[i];
			problem_area.appendChild(divTag);
			MathJax.Hub.Queue(["Typeset",MathJax.Hub,'step' + i]);
		}
		
	//	MathJax Queue for processing latex that javascript filled in
		MathJax.Hub.Queue(["Typeset",MathJax.Hub,'problem']);

Hi

I am trying to make all the cells within a table droppable spaces, using the scriptaculous library. However I am not able to do so, and I am not certain why. The table cells are creating within the javascript. I then try to apply the droppables to the table cells through iteration, through the function when the document loads. It does not seem to be working. The document accesses an external php page and has inline php within a div element. I am uncertain if by having the draggable elements instantiated within the php script, that this would be causing any problem, as I cannot see how this would be, the php draggables all appear to be corresponding to the css in the document. Any help with the droppables would be appreciated. I have set up a css class hover, so that when the draggable passes over the droppable the edges of the droppable area should be turning blue, but this is not happening. Not sure what the problem is.
