Printing An Array To Screen As Formatted Javascript
Jul 20, 2005
I have a three tier nested array, used to define a map for a javascript
game, and can be edited within the web page. Is there a way I can
generate a visible copy of this array that I can then c&p into a file? I
think the best solution would be to write into a popup window (this
popup would be purely for map development use, so I don't feel worried
by popup blockers, as only myself would be seeing the popup). However, I
have no idea how to:
a) create the string in a form that a html parser can display as
ready-formatted javascript code
this string will evaluate to a 2D array if I do this:var array = eval(string);But eval is not very safe.Is there a way to achieve the same effect (turn that string into 2d array) without using eval function?And I have no control over what string I am given, so will have to process this kind of a string =Right now I am thinking of writing a custom function which will split the string and then split again etc, but is there already something that can do this job?
I am building a web page.and have a simple javascript menu... I call the javascript menu within a div block that my print sytlesheet has set as a display: none;, well all the content in that block doesn't show up, EXCEPT the javascript is still getting run Code:
I very new to javascript. I have a php script that query a db and most of the time these reports are lengthly. When I use a print button and OnClick=window.print() it only prints what is currently displayed on the screen. Is there a way to print the entire report? Or if not what can be done?
I want to print tables on a regular printer with A4 paper. How do I send data to the printer? And is there a processor for sending html to the printer that the printer understands.
One solution is to open a new window with the javascript and execute a php script that generates tables on that page and then just executes the browsers print version.
However, that is not what I want. I want it to send data to the printer without having to ask the user of permission. Any solution?
I try to print out five hidden frames throug a printing-form. I use the frame.focus() and the frame.print() functions. Everything is fine except the following little disadvantage:
When I print out the five frames, the print window dialog appears five time (for each frame once). The user has to confirm his standard printer several times.
When designing a site, a request has come to me about printing web pages. What they want is the page to be broken up into frames, and only one frame will be able to be printed. so that if the page is broken into 3 vertical frames. Would it be possible to have it only print the middle page if the person clicked the print button.
This is so that even beginner users to IE or Netscrape would be able to get a printout of the page without having to change options in the print preferences.
* The example the person gave me was similar to Page Breaks in MS Excel. You can see the whole thing, but when print is clicked, you only get a certain section printing (even a beginner can do this).
I was wondering if it is possible to maximise a screen in javascript.
right now, I use this code:
A HREF="heritage.html" onClick="msgWindow=window.open ('heritage.html','fullWindow','toolbar=no,location =no,directories=no,status= no,menubar=no,scrollbars=yes,resizable=yes,width=8 30,height=630'); return false" onmouseover="window.status='open site in full screen' return true" CLASS=TP>open full screen</A>
, but I was wondering if we can fill the entire screen?
I have an appointment form with NAME, DATE, TIME, LOCATION. I want to add another set of these same field fields if I have more than one appointment to enter so all appointments are subitted on one form.
I also want the results to be in a layout other than the generic HTML or text layout used by Frontpage. Hope this is clear enough. Don't know if this is possible.
I am trying to create a mouseover (of an image)that generates text within <span> tags.The text is html formatted and could include images, links etc.Here is how I tried to code..
I am working on a calculator page for a clients site. I am using dreamweaver and form calculator made by Kaosr as behavior / plugins in dreamweaver. The way I have it set up is first the user enters some numbers in boxes, clicks a get refund now button and a div element appears with the answer. The whole calculator works..but I cant get the answer to appear in currency format. I've found tons of applets for javascript that change it into currency format upon clicking a button or clicking elsewhere on the page.. but none that automatically will make a text box display currency when the answer appears..
I'm using Tablesorter since few months and it was working very well.I did a small change yesterday in my php code: numbers over 1000 are nowformatted like this: 1 000, 1 000 000 instead of 1000 or 1000000.Since I did this change Tablesorter seems to have problems sorting this kindof formatted numbers with spaces. It just doesn't sort the way it should
I'm pretty new to jQuery and I'm using $.getJSON to submit some data to a PHP script which either returns 5 sets of json-formatted data or data to indicate an error condition (i.e., no data available) from the PHP database query. The callback routine handles the 5 sets of json-formatted data just fine (using $.each...) but I'm having trouble testing for either just a string with 'null' in it or a json-formatted data return of [{"error":"null"}].
My callback code for the second approach looks like this: function handle_stores(data) { if (data.error == "null") ..... But this test does not execute the following code for the 'true' condition, i.e., data.error == "null" never evaluates to 'true'.
I'm using this validation plugin alidation/and it is great.However, it rejects dates like 07-14-2009 as invalid. Is there someway to add a list of valid formats?If not, should I write my own method to match that particlar format?
I have 2 monitors from a different size. It is important in my application that I get the screen size of the monitor where the webbrowser is located. When I try to get the screen size (window.screen.height + window.screen.width) only IE gives me always the screen size of the main monitor where my taskbar (windows7) is located, instead of the screen size of the secondary screen where the webbrowser is located.
Is it possible in javascript to operate on an array without knowing how mamy elements it has? What i want to do is sending an array to a script, and this script should add all values from that array Could you show me a little example how to do this?
i have made an application in php so that people can make, on the fly, a form. when they submit the form there is a javascript formvalidation.
because we do not know how many fields there are in the form (it is made on the fly) i collect all the form fieldnames in an php array and sent it to the javascript function: Code:
I have a DataTable that I created in C# that looks like.
Column1 - Column2 - Column3 1 - a - b 2 - c - d 3 - e - f
Now if I want to get the value of column 3 with id 3 I simply need to do something like this (pseudo-code):
string value = dt.rows[3]["Column3"].ToString();
Is there a javascript object that mimics this same functionality? I am going to use my C# DataTable to create a javascript object that I can use for client-side functionality before posting back to the server.
Is it possible to have a JavaScript object that works just like a standard Array, except that when the array is modified, a function gets called which can then do some processing on the array?
Like this: // SpecialArray has a function called Notify function Notify() { // process the array with changes made } var myarray = new SpecialArray("zero", "one", "two", "three"); myarray[1] = "ein"; // after this change is made, function "Notify" is called
I know you can derive a new object from Array, but you cannot directly override the [] operator.
Can you add a function or event handler to a regular Array object that gets called when the array changes?
