JavaScript - Ie Says Undefined And Other Browser Come Back With A Value?
this function seems to be working fine in all browser but of course. I'm still a noob at JavaScript and well things like this just doesn't make sense.
when I go to alert this function in IE I get undefined. But other browser gives me a value. What am I doing wrong with this function? Code: function ext() {
var img = document.getElementById('photoSmall');
img = img.src;
if (typeof img == 'string' && img != 'undefined') {
var typeis = img.substr(-4);
if (typeis == '.png' || '.jpg' || '.gif') {
return typeis;
}
}
}
Thanks Jon W Similar TutorialsHello, I need some script to force the browser to reload/refresh when a page is reached from the back button. EG You're on page A -> You click a link onto page B -> You Press Browser back to go onto Page A, it has old content that requires a reload. Now, my page is currently php so I won't bother with my code here as I am looking for any solution (I have also posted in php forum). Any JS solution that will trigger a reload on browser back is appreciated. I have tried a few ideas, most work in Chrome, IE always works, Firefox 4 and Opera 11 wont reload, simply fetching from cache I believe. Thanks. Hi All, I am using a loop slider to scroll 4 pages. When I am on any page and click through the product on that. I go to the product but when I click the back button, it goes to the start of the slider rather then the page where I left it. How to go back in loop slider from a back button to the page where we left the scroller. Instead of going to the start of the scroller. It is annoying to go back again to start of the page and scroll all pages. Any help, Highly appreciated. Regards, Meenakshi. I am trying to write script that allows a user to select a new page using a select menu. But if a user changes mind and clicks Back button. i want a use to see again "Select a New Page" as a first option in the select menu. instead i see the page that was chosen before. in firefox, even when i click Refresh button, the select menu does not go back to its initial format. I tried to use the principle that each time window is loaded, the selected Index would be 0. it is not working. Could anyone give me a hint on how to fix this problem? my script is below. <html> <head> <title>Jump Menu 2</title> <script type="text/javascript"> function new_page() { var selectmenu=document.getElementById("states_form").states_select; selectmenu.onchange=function new_state() { var i=selectmenu.selectedIndex; var state=selectmenu.options[i].value; var new_page="http://www.50states.com/"+state+".htm"; location.href=new_page; window.onload=function select_reload() { i=0; } } } window.onload=new_page; </script> </head> <body> <form id="states_form"> <select name="states_select"> <option value="0"> -- Select a New State--</option> <option value="nebraska"> Nebraska</option> <option value="texas"> Texas</option> <option value="florida">Florida </option> <option value="oregon"> Oregon</option> <option value="wisconsi"> Wisconsin</option> </select> </form> </body> </html> Hi I am trying to trigger an event once the user clicks the browsers back/forward buttons, I have built a system just like facebook where if the user has javascript turned on they get the full feature of the site which includes fast switching for example if someone goes to this page "example.com/index.php" and click a link to contact.php it would change the url to "example.com/index.php#!/contact.php" but what I need to know is if there is any way to change the pages content when the user goes back and forth through the fast switch pages? something like "history.back !== -1" or something like that. If anyone can help please reply, thank you. It's a well documented issue- when you have a page that contains an iframe, and then navigate inside the iframe, hitting the browsers back button will only affect the contents of the iframe and not the entire page. I've been searching all over for solutions and cant find one that works for my current implementation. Anyone have any suggestions? Here is my code: js Code: function ShowPage(frame)
{
frames[0].location = frame+'.html'
frame.contentWindow.location.replace(newUrl);
}
Buttons that change the contents of the iframe Code: <div id="thumb1"><a onmouseover="ShowPage('frame1')"onclick="ShowPage('frame1')" rel="nofollow" target="mainbox"></a></div>
<div id="thumb2"><a onmouseover="ShowPage('frame2')"onclick="ShowPage('frame2')" rel="nofollow" target="mainbox"></a></div>
<div id="thumb3"><a onmouseover="ShowPage('frame3')"onclick="ShowPage('frame3')" rel="nofollow" target="mainbox"></a></div>
and then the iframe itself Code: <iframe src="frame1.html" type="text/html" style="border-width:0; border-style:hidden;" transparency="true" name="mainbox" frameborder="0" scrolling="no" width="700" height="807"> </iframe> Greetings, I am currently using the websites tutorial about browser detection using the navigator. http://www.javascriptkit.com/javatutors/navigator.shtml I am however finding myself unable to detect a pattern in order to learn from. My aim is to use Browser detection to have a CSS file for each browser type, such as Firefox, IE, Opera, Safari and then an overall CSS file if none of the above, to fix numerous flaws. For IE and Firefox using the site's code is all well and good and while I haven't tested it yet I'm wondering how to set up the coding so that it can detect a safari browser. There are lots of slashes and d's and brackets and I do find myself unable to understand their purpose. So if someone can explain how I could do it for Safari I would be very appreciative. I need a script that will redirect to a specific page is the browser is safari version 4. if the browser is NOT safari 4 I want the browser to stay on the current page.

here is the button code - Code: <span onclick="javascript:history.back()" style="text-decoration:underline; color:blue; cursor:hand">Back</span> Not sure how to explain this but...... Using a meta refresh to display a thankyou page for 5 seconds after a form submit, then return to form. If user clicks back to return to main page from form, returns to thankyou page instead, and has to go back to form again, then back to main page. I can have thankyou page return to main page, but would rather return to form. This is what it should do: main page -> form -> thankyou page -> form -> main page This is what it does: main -> form -> thankyou -> form -> thankyou -> form -> main Is there any way to remove thankyou page from history? Hello there, I'm a 30yr old returning to school and I signed up for a CMIS102 class, thinking it be more explanatory as the syllabus let on. But I was wrong. While I do understand some of what the professor has been teaching us, like modular programming and IfElse statements, I can't wrap my head around things like While Loops. My professor has saddled us with a couple assignments, requiring us to write in pseudocode and I was wondering if anyone could explain what he wants from this assignment or even help me with it, that maybe I can finally have a grasp of it, and will know what I'm doing on the final. ~Tia P.S. I've posted the assignment question below: I need to write a pseudo-codepseudocode for the following question but don't know how: Write a program to read a list of exam scores (in the range 0 to 100) and to output the total number of grades and the number of grades in each letter=grade category. The end input is indicated by a negative score as a sentinel value. (The negative value is used only to end the loop, so do not use it in the calculations. Example: 88 93 55 77 100 -1 (The output would be) Total number of grades = 5 Number of A's =2 Number of B's = 1 Number of C's =1 Number of D's = 0 Number of F's =1 Must prompt user to run again I need an html page that when visited automatically redirects the browser to return to the previous page it was on. here is the current code I have: Code: <head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

this works in firefox but in IE you have to press ok in the alert box before it returns. I admit I am a javascript novice. Any suggestions Hi, I currently have a <div> with a <p> and have an edit button that when clicked will transform it into a textarea using jQuery's .html(). I also have a cancel button which allows the user to cancel the edit and return the textarea to the previous content, any ideas how I do this? JavaScript Code: // JavaScript Document
jQuery(document).ready(function(e) {
$('#edit_p').click(function(e){
$('#cancel_p').show();
$('#greeting').html("<textarea id='txt_greeting' cols='20'>" + $('#greeting p').text() + "</textarea>");
$(this).hide();
});
$('#cancel_p').click(function(e){
$('#edit_p').show();
$(this).hide();
});
});

I need a back to top link on the bottom of my page that stays there all the time while people are scrolling.. is this possible? is this close to what i'm looking for? http://javascript.internet.com/page-...ting-link.html i've seen it on some other sites but I can't find any to reference now... I'm totally new to this! thanks for your help! -B I am making a simple puzzle game on Android using Phonegap, that is HTML5, CSS3 and JavaScript. When a user fills an answer on a page, if the answer is correct, it will go to another page. However, once the user goes to the next page, he/she CANNOT return back to the previous page. I do not want the user to return back, else he/she will have to fill the answer again to go to the next page, so it's not good. Thank overview: from my javascript, i call a function in the php block, that function successfully retrieves a value from the database, but when i pass that retrieved value back to the calling function....all is lost somehow. when i test this code by itself, it works fine and gets the correct number. <?php mysql_select_db($database_connFtH, $connFtH); $result = mysql_query("SELECT status_index FROM cpqc_status ORDER BY row_id DESC"); $row_result = mysql_fetch_assoc($result); $index = $row_result['status_index']; echo $row_result['status_index']; echo $index; echo "the value of index is ".$index; ?> however, when i set this same code up as a function to be called upon globally, and to return the value of $index, it all just seems to "not work". <?php function runStatus() { mysql_select_db($database_connFtH, $connFtH); $result = mysql_query("SELECT status_index FROM cpqc_status ORDER BY row_id DESC"); $row_result = mysql_fetch_assoc($result); $index = $row_result['status_index']; return ($index); } //end function runStatus() ?> the calling function, with an alert box to check if the value of $index was passed down accurately <script type="text/javascript"> var x = runStatus(); alert(x); </script> all i want to do is call a server-script function that deals with the database and gets me a value out of the database, and pass that value back to the calling function. can't figure out what is wrong. the "return($index)" should send back the value of $index. the call to that function should receive back a value and assign it to "x". and the alert(x) should spit it out with no problem. but......something is wrong and it won't work. any ideas what is wrong? it is my understanding that a function inside the php determants can be called upon from anywhere and that function can return a value.(?) argh!! i think i know why Einstein's hair was always so messy!! thanks, Paul Williams weather today in Kalispell, MT: 7 deg this morning, got a little snow last night, only about 6 or 8 inches, not much. maybe more later. I have a dropdown box "select Term" which has options Spring 2011, Summer I 2011, Summer II 2011, Fall 2011. alongwith another dropdown box which is populating from oracle DB. When the select term option changes, the second dropdown values changes( populate from the DB). When I change the option of the first one (i.e. spring 2011 to summer I 2011) I can see the query string canges: https://localhost/term/index.php?frmTerm=201107 and also I can see the second dropdown(populates from DB) changes according to the first selection No problem....BUT the first one is falling back to the default one" select term"as soon as the second list populates.Here is my code and I would really appreciate if you help PHP Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <SCRIPT language=JavaScript> function reload(form) { var val=form.myTerm.options[form.myTerm.options.selectedIndex].value; self.location='index.php?myTerm=' + val ; } </script> </head> <body> <?php include('conn.php'); ?> <form name = "schd" id="schd" action="drplist.php" method = "post"> <?php $var_term; @$term=$_GET['myTerm']; echo"<td>"; print "<select name='myTerm'onchange=\"reload(this.form)\">\n"; //1st dropdown code $query_term = "select term_code from myterm"; $stid_term = OCIParse($conn, $query_term); OCIExecute($stid_term,OCI_DEFAULT); print "<option value=''>Select Term</option>"; while (OCIFetchInto($stid_term,$row)) { foreach($row as $item) { //print "<option value='$item'>$item</option>"; if($item ==201101) { $var_term = "Spring 2011"; } elseif ($item == 201106){ $var_term = "Summer I 2011"; } elseif($item == 201107) { $var_term="Summer II 2011"; } elseif($item == 201109){ $var_term ="Fall 2011"; } else { echo "noterm"; } }//end foreach print"<option value = '$item'>$var_term</option>"; }//end while print "</select>\n"; OCILogoff($conn); echo " </td> "; print "<select name='frmPrefix'>\n"; //If the term is Summer I if(isset($term) and $term =='201106') { $quer="SELECT DISTINCT SUBJ_CODE||'-'||SUBJ_DESC FROM SUMMERI WHERE TERM_CODE = '".$term."'
