JavaScript - Confirm/searching/counting An Array
I feel stupid for asking a question about searching arrays, when there's a very similar thread that has been answered just recently on the first page; however, I'm still having trouble contemplating my own scenario.
Basically, my program prompts the user for the length of the array and then asks the user to fill the array with words. Here is where I need help: I want to confirm if the user wants to search the array for those words. If so, the user will then be prompted to enter the word he wishes to search for; if found, the location of that word will be reported and the number of times the word has been searched for will be kept track of in a separate array. Here is what I have so far: Code: /* -- phase 3 ------------------------------------------------------
search for words the user asks for
*/
// search variables
var response;
var search;
while (true) {
// confirmation protocol
response = confirm("Do you wish to search the lexicon for a word?")
if (response) {
search = prompt("What word would you like to search for?");
// alert("search");
}
else {
alert("Thank you for wasting my time.");
break;
}
// begin search protocol
for (i=0; i<words.length; i++) {
if (search==words[i]) { alert("Word found at" +i+);}
} // end for loop
else {alert("word not found.");}
// counter array/accumulator
var hits = new Array(words.length);
hits[i] = 0;
for (i=0; i<words.length; i++) {
if (words[i] == search) {
hits[i] = hits[i] + 1;
alert("This word has been searched for " +hits[i]+ "times.");
}
} // end for loop
} // end while
The problem with my search seems to be that the search is parsed through the for loop; if it finds the word it alerts me that it was found at i location, but then it continues through and sees that the search does not equal the other values in the array and reports it's not found as well. My counter array is completely off, and I'm really at a loss to figure it out. I can see that the problem might be that each new search resets the hits[i] to equal 0, so no matter how many times a word is searched for, it returns a count of 1. I really want this array to track the number of hits for each word searched for, but have no clue why it's not working. Thanks for any help I can get; and please, feel free to critique my coding style, I definitely need to improve. Similar TutorialsHi all, I have an array holding 100 randomly generated integers between 0-9 inclusive...firstArray[99] how do i use a second array to keep count of how many times each integer is generated..secondArray[9] All right, to start, I'll summarize what I'm doing currently... - Asks the User to select a date (year, month, day) via drop-down boxes - Converts whatever the user inputs to a formal that will match a string value found in an imported array in a .js file ... And what I'm having trouble with: - Searching through the imported array for a matching value - Printing whatever block of the array matches the value, as well as any others that also match the value. For starters, because the array I'm working with is enormous, I'll just make one up here that is still in the same format. In working with the main code, assume that this is the cdr.js file: Code: var cdr = [
{
"callid": "Guest User1",
"start": "2009-05-11 15:08:40",
"end": "2009-05-11 15:09:46",
"duration": "66",
},
{
"callid": "Guest User2",
"start": "2009-05-11 16:09:40",
"end": "2009-05-11 16:09:47",
"duration": "7",
},
{
"callid": "Guest User3",
"start": "2009-05-12 12:10:30",
"end": "2009-05-12 12:10:56",
"duration": "26",
},
{
"callid": "Guest User4",
"start": "2009-05-13 17:25:30",
"end": "2009-05-13 17:26:30",
"duration": "60",
}
];
So basically I want the search to be based on that "start" value, though only the date (which I assume would be doable by using .substring()) Now here is the actual code of the program: Code: <html>
<head>
<script type="text/javascript" src="cdr.js"></script>
<script>
function init()
{
// Grab the values that the user has entered
var theYear = (document.myForm.inputYear.value);
var theMonth = (document.myForm.inputMonth.value);
var theDay = (document.myForm.inputDay.value);
// Convert them to something that will match the string
theDate = (theYear + "-" + theMonth + "-" + theDay);
// The search needs to go here
}
</script>
<head>
<body>
Select a date which you would like to view the call statistics of:
<form name="myForm">
<select name ="inputYear">
<option value="2009">2009</option> <option value="2008">2008</option> <option value="2007">2007</option> <option value="2006">2006</option> <option value="2005">2005</option> <option value="2004">2004</option>
</select>
<select name ="inputMonth">
<option value="01">January</option> <option value="02">Februrary</option> <option value="03">March</option> <option value="04">April</option> <option value="05">May</option> <option value="06">June</option> <option value="07">July</option> <option value="08">August</option> <option value="09">September</option> <option value="10">October</option> <option value="11">November</option> <option value="12">December</option>
</select>
<select name = "inputDay">
<option value="01">1</option> <option value="02">2</option> <option value="03">3</option> <option value="04">4</option> <option value="05">5</option> <option value="06">6</option> <option value="07">7</option> <option value="08">8</option> <option value="09">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> <option value="13">13</option> <option value="14">14</option> <option value="15">15</option> <option value="16">16</option> <option value="17">17</option> <option value="18">18</option> <option value="19">19</option> <option value="20">20</option> <option value="21">21</option> <option value="22">22</option> <option value="23">23</option> <option value="24">24</option> <option value="25">25</option> <option value="26">26</option> <option value="27">27</option> <option value="28">28</option> <option value="29">29</option> <option value="30">30</option> <option value="31">31</option>
</select>
<input type="button" onclick="init()" value="View Date">
</form>
</body>
</html>
I've essentially left the section where the search code needs to be blank as I'm not even sure where to begin. Any help would be appreciated. Hi guys, I have an array which looks like this: var v=["It is my birthday today. ","How are you today. ","The weather is nice today. "]; I then, by using a function need to search for a specific word in the array, and if it is there, it alerts the word and "found", and if it isnt, it alerts the word and "not found". In the function below, a is the string/word which will be searched for in the array, and b is the array location to be searched. Therefore, if wordfind("birthday",0) was typed in, the value would be found. However, the code I have below is not working as I do not know how to make it so it knows that b is the array index to be searched and that a is the string value that will be searched for. Code: function wordfind(a,b){
var find = b.search(a)
if(find==-1) alert(a+" not found")
else alert(a+" found")
}
wordfind("birthday",0)
Any help on this would be fantastic, Mike Hi, I am trying to search an array for a string and then if it is found alert it. I have found examples of how to iterate the array and how to use .IndexOf to return a true false statement as to whether the array includes the string, but i don't know what to do after that and how to display the string if its found. Any help appreciated.. Thanks hey guys im not new to javascript but arrays still confuse me exspecialy when put into loops ok say i had 2 arrays i have used jquerry to extract a question lets say this is the question How long is a piece of string? the answer is for this example infinite so what i want to do is search the question trough a array with 21984 and more in the future when it finds the match it then looks at the answers array at the same array length as where the question was found then sends the answer to a variable for later use could someone give me a example on how to do this please? Code: <html>
<body>
<script type="text/javascript">
var Items = new Array
Items [0] = ["a", "b"];
Items [1] = ["c", "d"];
var i = 0;
if(Items [i++][0] == "c"){
document.write("hello");
}
</script>
</script>
<body>
</body>
</html>
so im trying to search an array with this function its not working i tried using firebug but it showed no errors. I think its the i++ part i want to increment i each time it tries it. WAIT SORRY I SOLVED IT I solved it you can put in Pistol or shotgun for name Code: <html>
<body>
<script type="text/javascript">
var Items = new Array
Items [0] = ["Pistol", "50", "2000"];
Items [1] = ["shotgun", "5000","1000"];
var i = 0;
function chek(){
if(Items [i][0] == document.getElementById("name").value){
document.getElementById("a").value = Items [i] [1];
document.getElementById("acc").value = Items [i] [2];
i=0;
}
else {
i++
}
}
</script>
</script>
<body>
Dammage<input type="text" id="a" />
<br/>
ACC<input type="text" id="acc" />
<br/>
Name<input type="text" id="name" />
<br/>
<input type="button" onclick="chek();" value="Chek" />
</body>
</html>
Is there anyway to make it more streamline so you dont have to click to increment? Hi guys, I'm trying to write a function such that it can be called, with a particular string specified in the call, and the function will then search a pre-defined array ("pages") of webpage URLs and headers in the form ["[www.sampleurl1.com] Sample Header 1. ", "[www.sampleurl2.com] Sample Header 2. "]; etc. etc., to see if the aforementioned string occurs in the "header" part of any of the indexes of the "pages" array, and then if it does, to alert "Found in x,y,z" where x y and z are the indexes of the "pages" array in which the specified string was found to occur. Here is what I have so far: Code: var pages=["[www.lboro.ac.uk] Loughborough University. ", "[www.oxford.ac.uk] Oxford University. "];
var founds=[]
function findIdxsC(s){
for(i=0;i<pages.length;i++)
if((pages[i].substring(pages[i].indexOf("]") + 1,pages[i].lastIndexOf("."))).match(/s/))
founds.push(pages[i])
}
var array=founds.filter(findIdxsC)
var arr2str=array.toStr;
alert("Found in "+arr2str);
findIdxsC("nIvERsi");
In theory, the above example should alert "Found in 0,1" because I have used the "match" command (so the search is case-insensitive) and the string "niversi" is found in the "header" parts of indexes 0 and 1. However, what it actually alerts is "Found in undefined". As far as I can see the problem lies with either the if-statement(and the associated command to "push" the indexes of "pages" for which the condition applies, to a new array, "founds") or with the filter and toString commands used towards the end. Perhaps it is one of these, or perhaps there is something else I am missing? Either way I would appreciate it if anyone could identify what in my code is causing the "Found in undefined" alert and suggest how I could rectify it, as it's causing me a bit of a headache Many thanks Hi, I am trying to give the user the option of music on my homepage (b/c we've all found it annoying at times...perhaps most times). I have found an "onload" option for the body tag on dotnetspider.com, but it doesn't seem to be working for me. Please take a look and let me know of any improvements I could make. Thx Code: <body onload="loadMusic()">

I amcalling a JS confirm function from my code behind like this: If bResetNewUser Then strMessage = "Your profile was successfully updated. Would you like to be redirected to the Inquiry screen?" ClientScript.RegisterStartupScript(Me.GetType(), "confSQUpdateScript", "ConfirmSQUpdate('" & strMessage & "');", True) My JS function is as follows: function ConfirmSQUpdate(message) { if (confirm(message)) { window.location = "ClaimantInquiry.aspx" }else { window.location = "http://www.labor.vermont.gov/" } } When I click the Update Profile button the first code snippet executes except no confirm message box appears and hence no redirect. The page says there is an error and the error is Object expected on the ClientScript... line. I have this same functionality with alert boxes and they all work. What gives? Hi, when my page loads it starts with a confrim box. If "Cancel" is selected then the rest of the page loads fine. If "Ok" is selected nothing after the confirm box loads. Any ideas. Also, it appears that IE and Firefox have trouble with this type of media and Chrome will only play the audio file for about 15 seconds. Any solutions?

Hello, this is not and advert This is a class i built in javascript What it dose: When users leave a site that has a confirm you want to leave box from the browser Why have i posted: I have seen around on the internet posts about how to do such a thing so i though i would get hits to codding forum when user search for such a thing and any one of codding forum members could help it get better Well this is a nice little object to use insted that dose a light box effect and brings up a Yes/no true/false box you set what you want it to say The JSON Object PHP Code: confirmBox = { 'message' : 'This is a Confirm Box', 'trueTxt' : 'True', 'complete' : true, 're' : '', 'falseTxt' : 'False', 'onTrue' : 'alert("true")', 'onFalse' : 'alert("false")', 'setTrue' : function(ontrue){ this.onTrue = ontrue + "confirmBox.update('true')"; }, 'setFalse' : function(onfalse){ this.onFalse = onfalse + "confirmBox.update('false')"; }, 'setTrueText' : function(trueText){ this.trueTxt = trueText; }, 'setFalseText' : function(falseText){ this.falseTxt = falseText; }, 'setText' : function(text){ this.message = text; }, 'hide' : function(){ var bg = document.getElementById('___confirmBox_bg'); var center = document.getElementById('___confirmBox_center'); var dialog = document.getElementById('___confirmBox_dilog'); center.removeChild(dialog); bg.removeChild(center); document.body.removeChild(bg); }, 'show' : function(){ this.createBG(); this.createCenter(); this.createDialog(); }, 'update' : function(sw){ this.re = sw; }, 'state':function(){ if(this.re = ''){ return false; }else{ return this.re; } }, 'createBG' : function(){ var bg = document.createElement("div"); bg.setAttribute('style', "display: table; position: absolute; top: 0%; left: 0%; width: 100%; height: 100%; background-color: black; z-index:1001; -moz-opacity: 0.8; opacity:.80; filter: alpha(opacity=80);"); bg.setAttribute('id', '___confirmBox_bg'); document.body.appendChild(bg); }, 'createCenter' : function(){ var center = document.createElement('div'); center.setAttribute('style',"#position: absolute; #top: 50%; display: table-cell; vertical-align: middle; margin-left:auto; margin-right:auto;"); center.setAttribute('id', '___confirmBox_center'); document.getElementById('___confirmBox_bg').appendChild(center); }, 'createDialog' : function(){ var dialog = document.createElement('div'); dialog.setAttribute('style', "display:block; width: 300px; padding: 16px; background-color: white; z-index:1003; margin-left:auto; margin-right:auto;"); dialog.setAttribute('id', '___confirmBox_dilog'); dialog.innerHTML = this.message + '<div align="right"><input type="button" onclick="eval(confirmBox.onTrue); confirmBox.hide();" value="' +this.trueTxt + '" /><input type="button" onclick="eval(confirmBox.onFalse); confirmBox.hide();" value="' + this.falseTxt + '" /></div>'; document.getElementById('___confirmBox_center').appendChild(dialog); }, } Then this is how you call it and set propertys Code: <script src="confirmBox.js" type="text/javascript"></script>
<script type="text/javascript">
confirmBox.setText("This is a test"); //Sets the text to show in the box
confirmBox.setTrueText("I can see it"); // sets the text on the return true button
confirmBox.setFalseText("I can't see it"); // sets the text on the return false button
confirmBox.setTrue('alert("Thanks");'); //what to do when true is clicked
confirmBox.setFalse('alert("Your a lier");');// what to do when false is clicked
confirmBox.show(); // Show the confirmBox
</script>
Ok, I need some help with this. When you click the close button on your browser, I want it to have a confirmation. Saying "**Click OK to be redirected to a new page**" something like that. If you click "OK" you are redirected to another page. If you hit CANCEL, then it closes out. It doesn't have to be a confirmation. Just needs to be something that has an option. (Maybe return xx?) Anyways, here's what I've got: Code: <script type="text/javascript" language="javascript">
var sure = false;
var lin = false;
function sureF()
{
if(!sure && !lin)
{
sure = true;
var con = confirm("**Are you sure you want to leave?**")
if(con == true)
{
location.href = "http://www.google.com/"
return con;
}
else
{
alert("Sorry")
}
}
}
window.onbeforeunload = sureF;
</script>
What that does, is when you click close on your browser, it will say "Are you sure you want to leave?" you click "OK", and you get redirected to google .com (How I set it) BUT then a popup comes up saying, "Are you sure you want to navigate away?" which I don't want at all. As you can see, my script is quite messed up. Could you help me out? Thanks. Hi I really really really need your help since I have no idea about this. How can I insert the Javascript Confirmation Alert into the del.php file? I have this del.php file PHP Code: <?php require ("include/config.php"); $id=$_REQUEST['id']; $strSQL = "DELETE FROM change WHERE id = '".$id."' "; $objQuery = odbc_exec($conn,$strSQL); if($objQuery) { echo "<script language='Javascript'>alert('Deleted.'); window.location=\""."index.php?action=syif\"</script>"; } else { echo "Error Delete [".$strSQL."]"; } odbc_close($conn); ?> This is the confirmation javascript Code: <html>
<head>
<script type="text/javascript">
function show_confirm()
{
var r=confirm("Delete?");
if (r==true)
{
alert("Deleted!");
}
else
{
alert("Cancelled!");
}
}
</script>
</head>
<body>
<input type="button" onclick="show_confirm()" value="Show confirm box" />
</body>
</html>
Hi Guys, I would like to add a confirmation to this: PHP Code: echo "<a href=\"delete.php?dir=$dir&file=$file\" onclick='return del(this, \"$id\")'><img src=\"images/delete.gif\" border=\"0\" /></a>"; However I seem to be struggling, severely! Any help would be greatly appreciated, especially if spelt out if alphabetti spaghetti. Kind Regards, Drew I've been trying to write a script that activates a confirm box when a browser window is closed. I want this to occur only when they try to close the window, not if they click on links on the page to navigate elsewhere. The confirm box then gives the option to continue closing as they intended or, if they click on ok (or cancel if it's easier), navigate to another page I specify. The script below works but it displays a confirm box when you close the window and click on links. Code: <script type="text/javascript">
function show_confirm()
{
var r=confirm("Wait! Would you like check out yahoo?");
if (r==true)
{
window.open("http://www.yahoo.com");
}
else
{
window.close();
}
}
window.onbeforeunload = show_confirm;
</script>
I understand you may be able to create a variable that you then attach to any links on the page you don't want to activate the confirm box. I don't know how to do this. Thank you. Hello, I'm new to Javascript, but have been programming in PHP and other web codes for 4 years now. I was wondering how you would check if a checkbox was ticked, upon its selection and then unhide HTML content, and then hide such content when deselected.. So far I have this: Code:
<script type="text/javascript">
function Agree() {
document.getElementById("stepTwo").className = "";
}
</script>
Which is called by onclick="Agree()" on the select box itself.. I understand an if statement is needed, but how would one go about doing this as my if statements do not appear to be working. Hi, im using this code as a fancybox replacement for confirm. Code: function fancyAlert(msg) {
jQuery.fancybox({
'modal' : true,
'content' : "<div style=\"margin:1px;width:240px;\">"+msg+"<div style=\"text-align:right;margin-top:10px;\"><input style=\"margin:3px;padding:0px;\" type=\"button\" onclick=\"jQuery.fancybox.close();\" value=\"Ok\"></div></div>"
});
}
function fancyConfirm(msg,callback) {
var ret;
jQuery.fancybox({
modal : true,
content : "<div style=\"margin:1px;width:240px;\">"+msg+"<div style=\"text-align:right;margin-top:10px;\"><input id=\"fancyConfirm_cancel\" style=\"margin:3px;padding:0px;\" type=\"button\" value=\"Cancel\"><input id=\"fancyConfirm_ok\" style=\"margin:3px;padding:0px;\" type=\"button\" value=\"Ok\"></div></div>",
onComplete : function() {
jQuery("#fancyConfirm_cancel").click(function() {
ret = false;
jQuery.fancybox.close();
})
jQuery("#fancyConfirm_ok").click(function() {
ret = true;
jQuery.fancybox.close();
})
},
onClosed : function() {
callback.call(this,ret);
}
});
}
function fancyConfirm_text() {
fancyConfirm("Ceci est un test", function(ret) {
alert(ret)
})
}
how can i use fancyConfirm via an onclick in a hyperlink? thanks for your help! I'm working on a bank website that needs disclaimers on their external links. I've searched for a tutorial or a script I could understand but need additional help if anyone is willing.. Here's my page with external links: http://designphilanthropy.org/services/links/ Here's the js I used from the previous bank design (I don't see any code here that will do what I need): Code: <script language="javascript">
<!-- Hide
window.resizeTo(440, 440);
function go() {
var width = screen.width;
var height = screen.height;
if(width<650) {
width = 600;
height = 400;
} else {
width = width - 200;
height = height - 100;
}
window.resizeTo(width, height);
location.href="";
}
// end Hide -->
</script>
And here's the code on the "yes" button: Code: <input type="button" VALUE="YES" onclick="javascript:go();"> The link opens the disclaimer and populates the url in the browser, but I don't know how to write the js for it to continue to the destination after clicking "yes" Any help would be greatly appreciated... how can you do onclick="return getconfirm('do you want to logout?');" onClick="window.location('logout.asp');" on the same button , if confirm then go url else stay here ? thank you ok so all I want to do is allow a user to confirm that they've clicked the deactivate button...if they click 'ok' deactivate the affiliate...else just return to the list what is happening is I click on deactivate and the confirmation pops up (so far so good); if I click ok then it deactivates the affiliate the way it's supposed to - but if I click cancel it still deactivates the affiliate instead of returning to the list Code: <script type="text/javascript">
function confirmation() {
if (confirm("Are you sure you want to deactivate this affiliate? Doing so will deactivate all of its users as well.")){
window.location = "affiliates.php?deactivate='.$_GET['deactivate'].'";
}
else {
window.location = "affiliates.php";
}
}
</script>
any help is greatly appreciated! |
