JavaScript - Need To Make A Website With The Following Functions, Please Help.. *total Newbie*
Hi!
I'm as new as they come when it deals with website development but forums have been useful to me in the past and I'm hoping I can get some kind of direction from all the wonderful people on this forum! I have an idea for a website that I'd like to pursue, and it would need functions such as: -Live news feed -Member logins, profiles, ability to rate/leave feedback for members -Mobile phone friendly -Comment on postings -Create an intro video (maybe even with animated stick figures to explain how the site works) -Accept paypal or other payment method -And basically, need to understand the monthly maintenance cost of all these functions, how to minimize expenses, etc. I know it seems far fetched for a newbie! But I need to know if this is possible.. how would I begin implementing a site like this.. Do I need to find a programmer to code it from scratch? Are there pre-written scripts available for all the functions I listed? What can I expect the costs to be? What's the best way to move forward? Similar Tutorialshi. i know a little php, but new to javascript. much of the syntax is identical. in reading the new rhino book (flanagan 6th), he gives the following example: Code: var square = function(x) {
return x*x;
};
okay, but then he does this: Code: square(plus1(y)) as an example of "invoking two functions in one expresson". (Prior he gives an example of defining a function with plus1, which is how I normally think of functions.) uh, square is a *variable*, but he is using it as a FUNCTION. Can somebody help me understand how this can be? how it works? I'm having trouble conceptualizng how we use a variable as a function. Hi Everyone I am trying to write some code to create an object in JS that contains the x,y coords for a shape i wish to draw. I create the shape, and then in a draw function I draw the shape to the screen from the object I created erlier. Trouble it is does not seem to work :S have anyone got and ideas? Code: var myShape = new newShape(200,200);
function init() {
canvas = document.getElementById("canvas");
ctx = canvas.getContext("2d");
return setInterval(draw, 50);
} // init
function newShape(x,y){
this.un_X=x
this.un_Y=y
function drawAll() {
ctx.beginPath();
ctx.arc(un_X,un_Y,30,0,Math.PI*2,true);
ctx.closePath();
ctx.stroke();
} // drawAll
} // newShape
function draw() {
ctx.clearRect(0, 0, WIDTH, HEIGHT);
myShape.drawAll();
} // draw
init();
Thanks in advance Is it possible to make a variable available to other functions outside a function So to make it global from within a function without using a callback Code: function() {
var something = 'hello';
}
function(something) {
document.write(something);
}
something like that possible?? I am working on a site and in the process borrowed some js from some one to get dropdown menus to work, but after a while got reports from people who tested my site of some problems and decided to verify all my code, and i have fixed most bugs but the one listed in the title. Code: sfHover = function() {
var sfEls = document.getElementById("nav").getElementsByTagName("LI");
for (var i=0; i<sfEls.length; i++) {
sfEls[i].onmouseover=function() {
this.className+=" sfhover";
};
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
};
}
};
if (window.attachEvent) {window.attachEvent("onload", sfHover);}
and i am verifying it on jslint the error i get is: Quote: Error: Problem at line 6 character 10: Don't make functions within a loop. }; Problem at line 9 character 10: Don't make functions within a loop. }; Implied global: sfHover 1,12, document 2, window 12 any help will be appreciated, and I'm sure this isn't complex but i don't know much js and want to keep it the same. I'm new to wordpress, I've just made a website and I want to make small modification: I want to remove the buttons in red. I thought it was CSS. But I've discovered that JS can't be overwritten by CSS so here I am. In firebug, I can see this: element.style { display: block; } When I change it to "display: none" buttons do disappear but I don't know in which file to find this sentence. A JS file is attached as txt. Can anybody give me a hand? This is the site: http://franciscourrea.com/sitio/ buttons by panchoskywalker, on Flickr Hello, Actually i know nothing about javascript. i have form and i need help to make javascript this is the form: </head> <SCRIPT language = "javascript"> function checkTotal() { function calculate() { A = parseFloat(document.form1.Qty.value); B = document.form1.selection.value; ---> 'please help i don't know the script command about onClick' and onChange combination' C = (A + B) * document.form1.total.value = C; } </SCRIPT> <body> <form name="form1" method="post" action=""> <table width="66%" border="0" id="form_table"> <caption> My Form </caption> <tr> <th width="41%"> <p>Qty ›</p></th> <td width="59%"><p> <input type="text" size="7" name="Qty"> <select name="selection" id="selection" onChange='Value'> <option value"1.00">Doll 1</option> <option value"2.00">Doll 2</option> <option value"3.00">Doll 3</option> <option value"4.00">Doll 4</option> </select> <br> Enter Qty and selection</p></td> </tr> <tr> <th>Merchandise ›</th> <td> <p> <input type="radio" name="None" value="0.00" onClick=""> None<br> <input type="radio" name="Key Chain 1" value="2.00" onClick=""checked> Key Chain 1<br> <input type="radio" name="Key Chain 2" value="3.00" onClick="" /> Key Chain 2</p></td> </tr> <tr> <th>Additional ›</th> <td><input type="checkbox" name="Story Book" value="4.00" onClick="" checked="checked" /> Story Book <br> <input type="checkbox" name="Mug" value="3.00" onClick="" /> Mug <br></td> </tr> <tr> <th>TOTAL›</th> <td><input type="text" style="background-color: #DCDDDD;" size="17" value="" name="Total" /></td> </tr> <tr> <th> </th> <td> <input type="submit" name="submit" value="Calculate" onClick = "javascript:calculate()"> <input type="reset" value="Reset"> </td> </tr> </table> </form> </body> </html> i need to get result from TOTAL checkout(input text) that sum from the value of options above (dropdown menu, checkbox, and radio button) multiplied by tax (4%) Coding master please help. Thank you very much. Good day! I am new in javascript function. I have Javascript code for auto calculate here is the code: Code: <script type="text/javascript" language="javascript">
function autocalearn(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, TotEarn = a = 0;
for (a; a < arguments.length; ++a) //loop through text elements
{
field = arguments[a];
val = parseFloat(field.value); //get value
if (!isNaN(val)) //number?
{
TotEarn += val; //accumulate
}
}
var tot=Number(TotEarn) + Number(document.getElementById('Amount').value);
oForm.TotEarn.value = tot.toFixed(2);
//oForm.TotEarn.value = TotEarn.toFixed(2); //out
}
</script>
<!--Total Deduction AutoCompute-->
<script type="text/javascript" language="javascript">
function autocalded(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, TotalDed = a = 0;
for (a; a < arguments.length; ++a) //loop through text elements
{
field = arguments[a];
val = parseFloat(field.value); //get value
if (!isNaN(val)) //number?
{
TotalDed += val; //accumulate
}
}
//oForm.TotalDed.value = TotalDed.toFixed(2); //out
var totded=Number(TotalDed) + Number(document.getElementById('Deductions').value);
oForm.TotalDed.value = totded.toFixed(2);
}
</script>
and now my problem is...I have a textbox for the overall total, and i want it automatic subtract the total earn and total deduction.. I will attach my codes for further understanding. Thank you in advance Can you tell me a similar way to do this? Greetings! I am currently working on my own company's website I am currently working with the FAQ page and I need to make a simple textbox, where visitors can type and ask a question and submit it, the question the visitor typed needs to be read by javascript from a seperate xml file which should be read with javascript. Now i dont know how to start with this and I would appreciate if someone could give me a lead on what things i should do and etc. Best regards Obs I heard that when we put javascript in website, then site takes time to open, is it correct ? If yes then which script is good for website.
hi everyone! i downloaded a Facebook Page template recently. the template works great, but i wanted to add one thing. here is the demo of the code: http://www.facebooktemplates2u.com/d...best_business/ here is where you can download the template: http://www.schoolofrok.com/facebook/html.zip/ anyhow, the part i want to change is the link that directs it to the content. for example, when you scroll over About Us, the little pop up from the bottom comes out. when you click it, it takes you to the About Us content. what i wanted to do, is make it so that when you click the whole jpg, it can take you to the content also. i noticed that the small link that pops up is too tiny and people get confused on where to click. any suggestions? TIA! Ok, so if you navigate ovr to my website "http://www.mancunianmacca.co.cc" you will notice that a box pops up asking for your name. When you type it in it adds it to the page. Is there a way I can get this to remember the users input and only ask them once then remember. Like cookie or anything. If you need any extra things. Just ask.
Hello, I would like to know how to make a website (in this case, a parent div) viewable only if JavaScript is enabled? I tried to develop a code that can do this, but could not find the solution. Code: <html>
<head>
<script type="text/javascript">
window.onload=function()
var="true"
if(JavaScript.enabled)
{
document.getElementById('true')
}
OnClick()
{document.getElementById('toggle').onclick=function()
{document.getElementById('jahava').style.display=(document.getElementById('jahava').style.display!='none')?'none':'';}}
</script>
</head>
<body>
<noscript>You must have JavaScript enabled to view the website.</noscript>
<div id="jahava">Contents Here</div>
</body>
</html>
Ok so im new to javascript and I have a button in an interface for an app. It's like drag and drop and i want this button to link you to a certain website searching for what the user types in the searchField1 box. The button is button16. Such as you type dogs into the text box and you click the google button among other search engines and it will redirect you to a google search doing a search for dogs. But how do I make this button search google and search for whats in searchField1. I would really appreciate the help. Im looking everywhere to learn this but just cant find it. If you could tell me how or send me a link to a tutorial that would be great. Thanks! Here is the code: I don't know where and what to add to do that. Please help. Hi, I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing. Can anyone see what I'm doing wrong? Code: function testWrapper()
{
function frequencyWrapperOne()
{
var numberArrayOne = new Array(0,0,0);
for (var i = 0; i < 1000; i = i + 1)
{
var chosenNumber = Math.floor(Math.random() * 3);
if (chosenNumber == 0)
{
numberArrayOne[0] = numberArrayOne[0] + 1;
}
if (chosenNumber == 1)
{
numberArrayOne[1] = numberArrayOne[1] + 1;
}
if (chosenNumber == 2)
{
numberArrayOne[2] = numberArrayOne[2] + 1;
}
}
return window.alert(numberArrayOne.join(','));
}
}
testWrapper();
Thanks. Is there a way to activate a function from another function? It has to be in the script tag, it can't be in the HTML section. Can I use something similar to this following code? If not, can anyone give me some help? I have tried to do it various ways, and have looked it up a few times, but to no avail. Can I use something similar to this following code? If not, can anyone give me some help? if (condition) {activate functionname();} Any help I can get would be appreciated. Thanks a lot to anyone who can help. Ok here is what I have so far, my ending part of my Call Function I think is ok. for my main function. I think I misplaced the { and } I will show you all the codes I have for my main function this is what I have I think I did misplace something but I can not pin point where that one small things should be Code: unction showResults(race,name,party,votes)
{ // script element to display the results of a particular race
var totalV = totalVotes(votes);
document.write("<h2>" + race + "</h2>");
document.write("<table cellspacing='0'>");
document.write("<tr>");
document.write("<th>Candidate</th>");
document.write("<th class ='num'>Votes</th>");
document.write("<th class='num'>%</th>");
document.write("</tr>");
}
for (var i=0; i < name.length; i++)
{
document.write("<tr>");
document.write("<td>" name[i] + "(" + party[i] + ")</td>");
document.write("td class='num'>" + votes[i] + "</td>");
var percent=calcPercent(votes[i], totalV)
document.write("<td class='num'>(" + percent +"%)</td>");
createBar(party[i],percent)
document.write("</tr>");
}
document.write("</table>");
}
</script>
Just wondering if i misplaced any ; or { or } anywhere suggestions? Here is my call function Code: <script type="text/javascript"> showResults(race[0],name1,party1,votes1); showResults(race[1],name2,party2,votes2); showResults(race[2],name3,party3,votes3); showResults(race[3],name4,party4,votes4); showResults(race[4],name5,party5,votes5); </script> I been going over this, I can not seem to figure out what { i might be missing? Thanks Dear Coders var amount1=12,345,678.10 var amount1=87,246,125.00 I want to sum amount1+amount2 as 99,591,803.10 Please help <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=us-ascii"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=us-ascii"> Code: <script type='text/javascript'>
