JavaScript - Array Searching Problem...probably A Simple Solution But I Can't See It
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 Similar TutorialsCode: <html>

<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");

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? but I just can't figure it out. I have trawled the net for a solution and tried many different things that I have seen but still no luck. Maybe the answer is staring me right in the face and I just can't see it. The code it executing the first time but as the setTimeout tries to start the second loop I get an error 'box is not defined'. Any suggestions and explanations of what I am doing wrong much appreciated! Code: function expand(box) {
var box = document.getElementById(box);
var originalHeight = parseInt(box.style.height);
var inc = 5;
newHeight = (originalHeight + inc);
box.style.height = newHeight + "px";
int = setTimeout('expand(box)',100); }
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>

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? 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. Im new to JavaScript so take it steady, i have an array: <script type="text/javascript"> var colOne [0] = new Array("Copyright", "Council - spending plans - consultation", "Data protection"); var colTwo [1] = new Array("Digital Region", "Freedom of information", "Libraries - online information resources"); var colThree [2] = new Array("Our standards", "Test"}; document.write(colOne[0]); </script> anyone can tell why it does not work? Ok...this is gonna sound very stupid to you guys, but I don't get one part of this code. Code: function range(upto) {
var result = [];
for (var i = 0; i <= upto; i++)
result[i] = i;
return result;
}
show(range(4));
What does result[i]=i mean? I know it adds the value of i into the array, but how? Why couldn't you just write it as result[i] or result[] = i? I have inherited some code, and cannot get it to work. Note the bold section in the OBJECT tag below. I believe this is where the issue is. Code: <script language="JavaScript">
var camArray = new Array();
camArray['Dolliver'] = "http://video.dot.ca.gov/asx/D5-Bello-at-101.asx";
camArray['Mattie'] = "http://video.dot.ca.gov/asx/D5-Mattie-Rd-at-101.asx";
camera="Dolliver";
var camHTMLd = "<object id='MediaPlayer' width=320 height=240 classid='CLSID:22D6f312-B0F6-11D0-94AB-0080C74C7E95' standby='Loading Windows Media Player components...' type='application/x-oleobject' codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,7,1112'><param name='filename' value='"+camArray[camera]+"'><param name='Showcontrols' value='False'><param name='autoStart' value='True'><embed type='application/x-mplayer2' src='"+camArray[camera]+"' width=320 height=240></embed></object>"
function changeCam(camera){
document.getElementById("caltransCamera").innerHTML = camHTMLd;
//alert(camHTMLd+camArray[camera]);
}
</script>
Then in the page, I have the following code: <a href="javascript:changeCam('Mattie');">101 at Mattie Road</a> It SHOULD open and start displaying the MATTIE cam, but it reloads the default Dolliver. What am I missing? Thank you in advance. hi there i'm a newb so be nice lol --> I want to use javascript in an array to submit content. I have some php background so using some techniques I worked this out. >> I need to select bathroom details and the script needs to be user friendly, however I have multiple bathrooms that can be selected. So based on a drop down list I need to select the bathrooms needed and then I will get more options as stated below.

CURRENTLY I have a drop down list from 1 to 6 when a bathroom is selected lets say 3 then it SHOULD display full - bath - shower - PER EACH BATHROOM if bath and shower is selected they disappear and full remains ticked if u tick full bath and shower disappear. included a sub cat. that changes based on the above selection this works in html but The bathroom varibles in the javascript need to be changed to suite a changing varible I based what I understand that an array will need to be added but how to i adjust the script correctly. I might work it out just have a bit of overload at the moment. Thanks in advance Okay, I am taking a js class and there is one minor bug that is driving me crazy with this assignment. First, here is the code I wrote, then my question: Code: var games = ["Jacks","Chutes and Ladders","Extreme Uno","Bopit","Barbie Doll"];
var price = [4.00,15.99,25.00,27.99,32.00];
var inventory = [40,15,30,20,40];
//I could not figure out how to make this work without assigning values first. It was giving NaN.
var subtotal = [0,0,0,0,0];
var qtySold = [0,0,0,0,0];
function chooseItem() {
var answer = 0;
while (answer != 6) {
var orderForm = "Choose a number below:\n";
for (var i=0; i<games.length; i++) {
orderForm = orderForm + (i + 1) + ".) " + games[i] + ": # in stock: " + inventory[i] + "\n";
}
orderForm = orderForm + "6.) Show Sales Summary";
answer = prompt(orderForm);
answer = parseFloat(answer);
if(answer != 6 && answer >= 1 && answer < games.length+1) {
var qty = prompt("How many " + games[answer-1] + " would you like?");
qtySold[answer-1] = parseFloat(qtySold[answer-1]) + parseFloat(qty);
subtotal[answer-1] = qtySold[answer-1] * price[answer-1];
} else if (answer < 1 || answer > 6) {
alert("Invalid Answer");
} else {
alert("Click OK to see your summary:");
}
}
var summary = "Your Sales: \n";
for (var j=0; j<qtySold.length; j++) {
summary = summary + qtySold[j] + " " + games[j] + " at " + currency(price[j]) + " each for a total of " + currency(subtotal[j]) + "\n";
}
alert(summary);
}
So basically, the arrays subtotal and qtySold need to retain values in case the "customer" chooses to add more of the same item in each order. What you see above works; however, when I alert the summary, it lists all of the items, even if there were none ordered. It simply says 0, but that is not what I want. Basically, I only want the total to reflect only the items that were actually selected. I do not what to do it this way: Code: var subtotal = [0,0,0,0,0]; var qtySold = [0,0,0,0,0]; I can effectively do this by NOT assigning any values to the qtySold array in the beginning: i.e. doing it this way: Code: var subtotal = new Array(); var qtySold = new Array(); The only problem is that when I do this, I get NaN at this point: Code: qtySold[answer-1] = parseFloat(qtySold[answer-1]) + parseFloat(qty); subtotal[answer-1] = qtySold[answer-1] * price[answer-1]; obviously, this is because I am referencing qtySold[answer-1] directly in the loop - so the first time through, there is nothing assigned. I can't (just before this line) assign 0 to each array item - to get it defined because if the user goes back in and adds more, it will always reset the number back to 0, which is not what I wanted. I tried adding an if..else statement instead, but cannot figure out how to get that to work? What are my options here? Thanks! Mike Ok guys, im willing to pay for the solution, got to get this site finished today!! Im having some trouble with a site im working on. In a nutshell, im using a navigation bar with dropdown and JS Fadeshow. When using the navbar dropdown, it goes BEHIND the fade show. If anyone could advise it would be great! I didnt attach the code as i think the best thing to do is just take a look yourself. Its alhambrarenovations. COM Thanks in advance Tell me what other info you need and i'll suply it. Hi all, I'm pretty new to javascript coding and was trying to make a fading image slideshow. i have found one on dynamicdrive modified it, all looks fine.

var the_rad_val=n;
if (the_rad_val.value='n')
{
function removeLink();
}
else
{
function restoreLink();
}
</script>
The 2 functions a Code: function removeLink() {
document.getElementById("mydiv").style.visibility = "hidden";
}
function restoreLink() {
document.getElementById("mydiv").style.visibility = "visible";
} // end function
Guess I did something wrong because the "mydiv" is visible when it shouldn't be Can someone help me out as I am not too good with javascript . Thank you. . Hey guys, I'm new to jquery and I'm sure this is a VERY simple problem.. Here's my code Quote: <style type="text/css"> #box { background: red; width: 300px; height: 300px; display: none; } </style> <script type="text/javascript"> $(function() { $('a').click(function() { $('#box').slideDown(4000); }); }); </script> </head> <body> <div id="box"></div> <a href="#">Click Me!</a> </body> </html> As you can see it's pretty simple, I've made the box slideIn. My problem is I want to make a separate button to slide it back out, but because I've used the "a" tag it's associating all links with the same function, how do I get around this? I'm sure it's really simple! Thanks Hi, javascript method downloadUrl() is very very slow at chrome. means, i am not able to see the data from mysql server at chrome browser.. But this works fine at IE. Pls suggest me with some alternative javascript methods.. thanks, VK I am a govt. employee wanting to make a multi-user database. This is a replacement for the current solution: 1. Single-user Excel sheet on a shared network folder. Here are my design limits: 1. The system uses Windows XP only. 2. I do not have communication with the network admins. 3. I will never have permission to install servers anywhere. They are forbidden. 4. I do not have permission to install any software on any computer. 5. My group only has access to one shared network folder. I've brainstormed some solutions, including: A. Marrying a VB Application with SQLite, with the SQLite file sitting in the shared folder. B. Using how to use SharePoint to develop my application. C. Using Microsoft Access as a client-side GUI which connects to another .mdb on the shared folder. D. Using Internet Explorer with Javascript and ADO ActiveX Objects to manipulate records in a .mdb on the shared folder. I choose D. Choice A is out because I can not install any software development tools. B may not work for me because my database is heirarchical in nature and I want more control over the GUI. Same reason for C, and Access is a little micky-mouse. Amazingly, the security settings on IE allow the creation of ActiveX objects through Javascript. I can also develop with javascript because I have Wordpad. To test the code I can simply run it by launching the HTML. This allows users to open the same HTML file in the shared folder instead of distributing front-ends. The javascript must all be client-side, including all data manipulation. However, I am not concerned about security issues because only our group will be using the system, and all traffic is already contained within Navy networks. So I don't care if I use window.location for storing variables since it works for this case. Does anyone have anything to say about this? I'm looking for pointers, gotchas, guidelines, and any other, better solutions. Thanks. |
