If I had a webpage that displayed a database in tabular form, it would
be nice to know how many lines of text the browser could display
without scrolling, then have the cgi script output the appropriate
number of lines of data to fill the screen.
I've seen examples of how to get the browser window size in pixels, but
is there a way to determine the number of lines that are displayed?
Im trying to find the correct syntax to use to determine whether which form
element is visible on changing the value in a dropdown list
I need something in the onChange of the dropdown list that will cause the
appropriate element on another part of the page to be displayed Code:
var mydropdownlist =
document.questform.typeid.options[document.questform.typeid.selectedIndex].v
alue;
if(mydropdownlist<6)
then display <input name="ans1" type="text" >
else
display <textarea name="ans1" rows="1" ></textarea>
Does anyone know how I could (in javascript, or any client-side lang) cound the number of lines in a given textfile?

Look at Navigation and then look at Animated Menus as an example. When the grey animated menus (div.columnrt) takes up two lines (could be more), need the corresponding left div (div.columnleft) to be same number of lines, so that everything stays lined up. Each of these pairs sits inside of a li element.
I have a textarea with a specific width. I have wrap="off" set because I don't want to force my users to wrap if they don't want to. The reason for this is because this textarea is where the user is typing an email message. However I have a background image set on the textarea with a verticle line going down the textarea which indicates to the user the "Recommend Width"What I want to do is provide them with a link to click on which says something like "Wrap Lines" and when they click on it, the text within the textarea would wrap to the "Recommended Width" line in the background image. The maximum length of a line should be 53 characters when they click on "Wrap Lines" link.So I did some searching around and the code I came up with is:
Code:
function showLines(max, text) {
max--;
text = "" + text;
var temp = "";
var chcount = 0;

This works with the first calculations such as average but right at they very end the the alert wont display the highest average it just displays the one which has a negative number typed in to it.

// calculates reservation duration
function resDuration(#Starts, #Ends) {
var date1 = new Date(#Starts.value);
var date2 = new Date(#Ends.value);
var minutes = 1000*60;
var hours = minutes*60;
var days = hours*24;
var diff = Math.abs(date2.getTime() - date1.getTime());
return round(diff / days);

/* put that value in elapsed days field */
$('#Days').val(diff);
I will then do validation on the result - input field "Days".
I have been presented with: Draw a flowchart and write a javascript program which will accept two numbers from a user and will determine whether the second number is a factor of the first. This is determined by dividing the first number by the second and checking if the remainder is 0. This is made easier if you find out what the operator does. The output should be in the form 4 is not a factor of 6 and 3 is a factor of 6. I have tried a few attemps and yet still not sure what the problem is :confused:

I'm currently working on a javascript form validator and have run into a problem. The validator is used to make sure that the customer has entered a number in the quantity input box of the item they wish to purchase.
Code:
function validateRE(fieldToCheck, strRegExp, msg, min, max) {
if (!min) { min = 0 }
if (!max) { max = 100 }
for (i=0;i<15;i++)
{
if (fieldToCheck[i].value) {
var re_pattern = strRegExp;
if (!re_pattern.test(fieldToCheck[i].value) || fieldToCheck[i].value.length < min || fieldToCheck[i].value.length > max) {
alert(msg);
fieldToCheck[i].focus();
fieldToCheck[i].select();
return false;
}
}
}
return true;
}
Used with:
Code:
<form method="post" action="../some_URL"
onsubmit="return (
validateRE(this.quantity, /^[1-9]{1}$|^[0-9]{2,3}$/,
'Please enter a Quantity.', 1, 3)
);">

The number of items that is under a specific product is generated dynamically and can range from 2-20. How can I get javascript to count the total number of items and run "for i=0;i<total number" instead so it is different for each product page?
I was just wondering if there is a way to load a CSS file depending on the browser that you are using. In this case I am looking to load a CSS file for Safari only. maybe another option would be to use CSS hacks (but not webkit).
View 1 Replies View RelatedWhile using jQuery, I found that I needed to know how many records were returned and also if the result set returned was empty. After searching the jQuery documentation I couldn't find any property or method that returned this value, so I've added that functionality
myself and wanted to share it with the group.
1) Determine the number of records returned: I wanted to show the user how many results were returned after they start typing into the autocomplete field similar to how Google indicates the number of results found when you start typing in the search box. At first I thought the max parameter in the function formatItem returned this value. However, it returns the max option that you set it to. So if your query returns 100 records and you set max to 25, it'll obviously return 25 (not what I wanted).So after trying various things, I looked at the jQuery code and simply added the number of records returned by the database to the formateItem function. In the fillList() function around line 660 I added the data.length parameter:
var formatted = options.formatItem(data[i].data, i+1, max, data [i].value, term, data.length);And in my autocomplete code, I added the parameter to the end of theparam list:formatItem: function(data, i, total, value, searchTerm, totalResults)So now whenever a new search is preformed, I get back the number ofsearch result from the database.
2) Determine if a result set returned was empty I wanted to update a <div> with a message like "no records found" whenever the query yielded no results. Again, after searching the jQuery documentation, I couldn't find any property or method that would indicate this so I added it to the code. In the request function after the line var data = cache.load(term); I added the following:
if (!data) {
options.isEmpty(0);
} else {

I'm using a Volusion shopping cart and it uses JavaScript to insert code into DIVs with specific IDs. The code that it inserts can't be changed from the backend, so I'm wondering if there is a way to replace it with JavaScript after it's rendered.
Here is my problem specifically: I'm trying to change the wording "Find by Type" to "Sort by Type", but I can't modify it since it's being added in later by JavaScript. The tag I have in my template file is:

I've copied and customized a script to display a css popup in my little website. The script should display a popup in the middle of the browser window, graying out the background, Everything seems to work fine except that at the end of the script, the page is displayed from the top. This means that if you click on the popup link from a position down in the page, you'll miss it because you will be taken to the top of the page, where you can't see it.
This is the HTML and CSS code:

And the js:

I've been debugging with alert boxes and everything seems to be fine until the script ends execution. Then the user is brought again at the top of the page...
In my final site the only thing I would like to show in the popup is a Flash movie.

I have an upload file operation in the web application. UploadForm.jsp
is the form, and UploadAction.jsp is the form processing. The web server is
Websphere.
//UploadForm.jsp
<FORM NAME="InputForm" ACTION="UploadAction.jsp" METHOD="POST"
enctype=multipart/form-data>
<input type="file" name="fileName">
//etc ...
</FORM>
After I deploy the application to the web server, if I upload a small
file size, it is fine.
But if I upload a huge file size more than 10MB, then it cannot even go
to UploadAction.jsp.
After 30 seconds, it has error "The page cannot be displayed" shown on
the web browser.
It cannot even go to UploadAction.jsp. But both UploadForm.jsp and
UnploadAction.jsp are in the same machine.
Interestingly, if I test in local machine, I can upload any file size
without problem. I don't have any hints now. any ideas?
