JavaScript - Newbie, Cant Get Method Argument Passed To Function To Document.write
Hi,
New to JS. Have ordered some new books, but need to get somethings going in the mean time. What I wanted to do is to link to a new page having a date range input in the form of 6 text boxes, 2 sets of mm-dd-yy, from and to, where the upon loading the page box 1 of the from would auto focus and then auto tab and then post where php could take over on the server side. Setting up the form and the lay out, no problem. Auto focusing went just like expected using the following code, included because on the next step everything fell apart. [/CODE] <script type="text/javascript" > window.onload=function() { document.getElementById("input1").focus(); } </script> [/CODE] So then the wheels came off and in response, began to simplify what was trying to be done to find where the issues were. As far as I can get working is: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc() {
alert("is this working");
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc()" maxlength="2" value="type a No." />
</body>
</html>
First issue with this: When I first get to the page everything is just as ordered. The focus is on the text box and the default value is "type a No." When I press a key onkeyup, I bring up the alert box with "is this working" in it. But when I refresh the page with the refresh button, after clicking the "ok" on the alert box, the character that was typed in is still displayed. If I use the link to the page, or the URL from the address bar, then the page reloads properly with the default value, "type a No". Question 1: How do you get the default textbox value using the refresh button as apposed to reloading the page using a link or from the address bar? Using Firefox 8.0 Second and more important at the moment: If I change the script to pass an argument to the function the script crashes. It does not pull up an alert box and freezes. My guess is that I'm doing something wrong on a concept level. NOTE: changed the default value of the text box to " ". Looked like to me there was an issue with the size specification and the default string length as you could only enter in a key stroke by highlighting the text and replacing it Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc(awe) {
alert(awe);
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc("123")" maxlength="2" value="" />
</body>
</html>
Question 2: can someone straighten me out with this? Similar TutorialsHi All, I have a problem in which I try to execute a funcition via a document.write() and it throws an "object expected" error. Overall I am making an interface for MS ACCESS .mdb table via ADODB using JavaScript and I want to be able to click on a link and the id is used to delete that entry. Code: My function is: Code: function deleteRecord(del)
{
var adoConn = new ActiveXObject("ADODB.Connection");
var adoRS = new ActiveXObject("ADODB.Recordset");
adoConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source = {path to }knowBA.mdb'");
adoRS.Open("Select * From know where ID="+ del, adoConn, 1, 3);
adoRS.Delete;
adoRS.Close();
adoConn.Close();
}
The code using the funcition is - oh and the numric KEY is rs(0) : Code: if(!rs.bof) {
document.write("<table width='700' border='1' align='center' cellpadding='2' cellspacing='0' bgcolor='#FFFFFF'>");
rs.MoveFirst()
while(!rs.eof) {
document.write("<tr><td><div align='center'><strong>"+rs(1)+"</strong></div>");
document.write("<strong>Keyword(s):</strong> "+rs(3));
document.write("<br><strong>Entry:</strong> " +rs(2)+" ");
document.write("<A HREF='javascript:onClick=("+"eval(deleteRecord(" +rs(0)+"))"+")'>delete</A> ");
document.write("</td></tr>");
cnt=cnt+1;
rs.MoveNext()
}
document.write("</table></form>");
}
if (cnt==0){ alert ("Sorry, there are no results on that search.");}
rs.close()
cn.Close();
}
</script>
Thanks for any hints on how to accomplish this! ok so Code: document.write("Goodbye!");
works but I put ^ that inside a function Code: function SayHello ()
(
document.write("Goodbye!");
)
and it stops working? I know the function call works because when I place some code to display an image in SayHello function, it displays the image. I'm working on a website that will basically embed a widget/frame sent by a handler into a user's current page. The user basically adds a script tag to where they would like the HTML to be. The script tag has their settings and is basically a document.write that calls all the code that we want displayed. So here's my problem. We have a map that we need to add in a specific section, and to get the map we have to call another script tag. So we end up having a script tag (map) embedded in another script tag (the code for the widget/frame) or we end up having to document.write inside a document.write. Now this works just fine and as expected in Firefox, Safari, and Chrome. However, Internet Explorer and Opera wait until the first document.write is completely finished before calling the embedded one. Of course the problem with this, is that it takes the map out of the document's flow and just appends it to the bottom left of the page. Since the rest of the page has already been called, there's no way to move the interior "map" script. Any ideas? Basically just trying to figure out how (if even possible) to render an embedded script tag in Internet Explorer and be able to place it properly. I've tried everything that I can think of, including AJAX and Google's unescape script. Any suggestions, I'd greatly appreciate it. Or even if you've encountered a similar problem, and know that it just isn't possible in IE or Opera, that would be fine too. Thanks in advance! My code is here and it works ... However, I would like my dynamic table to show on the same page as my body and not on a new blank page. I have created a DIV and try playing around with the document.getElementById('monTab').innerHTML but it's not working out for me ... What am i missing ?

Hi i have a function (i wont write it out coz it is too long!) but after i have done the main calculations within this function i wont to display some of the variables in a table. i have writen: document.write( <table border="1"> <tr><td> Value 1 </td><td> document.write(a); //here * </td></tr> </table> ); were it says "here *" i wont to write within the table variable a (which i have defined properly in the function). However, as i have already written document.write it actually displays the text "document.write(a);" instead of the value for var a. Help asap please as it in for school soon! Thanks in advanced :D Hi, I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it? intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\' I am posting my javascript function he <a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a> function OpenDocPreview(url, docname) { alert('message from search base : ' + url + ' ' + docname); } thank you, Hello, I'm new to Javascript. I know how to make a script that when you click on a button it changes a variable. I also know that with document.write I can express this variable but I do not know how to refresh document.write! For example, if I have a var car =3 and when I click on a button car++ (or increases by 1 so it becomes 4 then 5 and so forth depending how many times you click the button) and I write document.write (car), it only shows the 3 and no matter how many times I click on the button, the 3 doesn't change. How can I get the document.write to show the updated variable? Thanks! So I want to have a button that when I click it will change this variable and that number will change live on the page. What is an alternative to document.write? I know I could use <p> in html </p> I would like to use JS though. I hope you can understand my question. I am 14yo and this is not for homework. I just wanna try and learn JS. I read document.write can cause me problems. But all I ever see is: <script type="text/javascript"> document.write("any words"); </script> what alternate could I use? Hi all, I'm working on an internal site for my company and I have a snippet of code that works 100% fine indepentantly but when I try to use it inside a document.write I can't get it to work. I'm pretty sure it's down to the structure of it but I'm inexperienced with JS so I'm not sure how do correctly structure it. Here is the code I want inside of a document.write(): Code: <a href='javascript: void(0);' style="text-decoration:none; font-size:14px;" onclick="
document.getElementById('my_hidden_div_id_1').innerHTML = '<iframe src=\'{file:link}\' width=\'880\' height=\'500\'></iframe>'
$('#my_hidden_div_id_1').koverlay({title: '{file:filename}'});
$('.css_koverlay').css({'background-color':'#9c183a'});
;
">
Pop-Up</a>
Could anyone help me correctly insert it inside document.write() so that it outputs without errors? Thanks! Im having an issue placing a document.write output in a specifc place (after my form), i want the document.write output to be produced from an if statement which is based on a variable within a function the document.write output is to be placed outside the script thought :S into another div CODE if (count<5) { document.write('unlucky') } any ideas? is there any alternative to document.write() which writes only in a specific part of document, does not overwrite whole document. and yeah, in this case the document.getElementById().innerHTML dosent work either, coz its in a loop, here's the code if you wanna see: Code: if (aa==1)
{
for (i=0;i<a.length;i++)
{
c = txt;
b = a[i].childNodes[0].nodeValue; // a is already assigned someplace in a xml document.
txt = (b==" T4 ")? "T4 <br />": "";
document.write(c);
}
}
Note: in the above code, the code: Code: txt = (b==" T4 ")? "T4 <br />": ""; is same as (also can be written as ) the code : Code: if (b==" T4 ")
{
txt = "T4 <br />" ;
}
else
{
txt = "" ;
}
document.write("<script type='text/javascript' src='http://www.website.com/javscript.js'></script>"); For some reason this will not output correctly. It ouputs "); Which is the last three characters. I am very new to JavaScript, however I already seem semi-stumped. The tutorial I am using, mentions that for tutorial example purposes they use document.write() however it suggests that I avoid using this as it will overwrite the whole HTML page. I know that I can use document.getElementById() for some things... however this begs my question: When do you use document.write(), when do you use document.getElementById() and is there also another method you use to change/write to the HTML Document using JavaScript? Otherwise, do you just use document.getElementById() quite a lot in JavaScript? Like I said, I'm very new to JavaScript, so it's all still very new to me. Cheers, Asher Hello again, I've continued to study and work on JavaScript. I've had some problems with the document.write() function. When I try to do a math problem, the whole content of the page clears out and only displays the solution. For example: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled</title>
<script type="text/javascript">
function jahava()
{
var h = 1
var r = 4
var t = 5
document.write(h += r += t)
}
</script>
</head>
<body>
<button OnClick="jahava()">Click Me!</button>
</body>
</html>
So If I put other content, like the button I was displaying (which I wanted to stay visible), the function would make them all disappear. I would again appreciate any help towards this matter. Sincerely, Taro B. PS; This is not a calculator related problem, just in-general. I have a series of videos which must be loaded dynamically on their pages which then get loaded into an iframe. I need to be able to load these videos using variables for the width and height. It's imperative that I use variables as the sizes of the movies will be determined by the user's resolution. Here's the code I'm currently using Code: <script type="text/javascript">
var dimW = screen.width;
var dimH = screen.height;
var w1 = dimW.toString();
var h1 = dimH.toString();
document.write('<OBJECT ID="Player" width="'+w1+'" height="'+h1+'" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" style=border:0px;">\n');
document.write('<PARAM name="autoStart" value="True">\n');
document.write('<PARAM name="uiMode" value="full">\n');
document.write('<PARAM name="volume" value="50">\n');
document.write('<PARAM name="mute" value="false">\n');
document.write('<PARAM name="URL" value="../../../videos/oracleChangeLocation_1.wmv">\n');
document.write('<embed src="../../../videos/oracleChangeLocation_1.wmv" width="'+w1+'" height="'+h1+'" autoStart="True" uiMode="full" volume="50" mute="false">\n');
document.write('</embed>\n');
document.write('</OBJECT>\n');
</script>
I'm developing in xhtml so naturally, IE doesn't recognize the document.write statements and the page comes up blank in IE. It works flawlessly in FireFox (as expected). So, I need to replace the document.write statements with something else while still being able to pass variables for the movie objects height & width. I've tried this code: Code: <script type="text/javascript">
//alert("The beginning");
var dimW = window.innerWidth;
var dimH = window.innerHeight;
var w1 = dimW.toString();
var h1 = dimH.toString();
var theNewMovie = document.createElement('p');
var theTextOfTheMovie = document.createTextNode('<OBJECT ID="Player" width="'+w1+'" height="'+h1+'" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" style=border:0px;">\n<PARAM name="autoStart" value="True">\n<PARAM name="uiMode" value="full">\n<PARAM name="volume" value="50">\n<PARAM name="mute" value="false">\n<PARAM name="URL" value="../../../videos/oracleWelcome_1.wmv">\n<embed src="../../../videos/oracleWelcome_1.wmv" width="'+w1+'" height="'+h1+'" autoStart="True" uiMode="full" volume="50" mute="false">\n</embed>\n</OBJECT>\n');
theNewMovie.appendChild(theTextOfTheMovie);
document.getElementById('mediaPlayer').appendChild(theNewMovie);
</script>
. I then have a <td> with the id of "mediaPlayer" but nothing is showing up. Most likely because I'm still fairly new to javascript and am probably forgetting or overlooking something. Can anyone give me any ideas, suggestions, or pointers as to what I am doing wrong? Thanks! M This seems like it should be easy but I can't figure it out. I am trying to set up a drop down list to interpret an abbreviation and to also hyper link to a site about the object. I want it to stay in the <textarea> and not write a new document but it is the only way I have been able to get a hyperlink. Any suggestions would be appreciated.

Problem is I want to change that name to verifypage.php When I replace sform with the verifypage.php I believe (I have no clues on JS) that the . if the extension of verifypage.php is screwing the code up. It's a dynamic drop down list that I want to display the results on another page. Thanks!
