I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper() { function frequencyWrapperOne() {
I am just trying to learn a little bit about jQuery.Now I have a problem with returning a value from a function.The following code works fine, when I tested it with alert(price) or any other way of echoing the value directly. But if I try something like var test = getPrice(324), the variable test would always be undefined.
function getPrice(id) { $.get('db.xml', function(d){[code]....
I assume that the nested functions are part of the problem,
s1 + "ript>"); } and then c.js I tried the s1="" from another googled post - no joy. if I change a.html to <script language='JavaScript' src='cb.js'></script> <script language='JavaScript' src='b.js'></script><script>Function();</script> it works.
I am learning HTML for the first time taking a self teaching class though my local Community College. Normally this college rocks and has some of the best resources and down to earth teachers that pick books that acutally help folks.
Well they failed and my book take more logic jumps that Stephen Hawkins! :D
So my ultimate question is as follows:
How do I created a function with the following information provided:
Create a fucntion named Mquote that contains the single parameter, Qnum.
My apologies for such little information. I am sure its my oversight that I am unable to locate the answer to my question.
What I am looking for is the base layout for noob java functions.
I have some javascript functions in an xslt file. Everything works and produces the desired html, except when using the visual studio debugger which gives the error "objects of type 'Script1' do not have such a member" and references the line and column where the "this" object is used, as in this.hourarray()
I wrote a funtion for all my <a href=...> tags. If I use the function, it looks like this: <a href="test.html" onFocus="myfunction()">
What I want is to automatically add myfunction() to all the links on a page. So I don't want to add onFocus=blablabla each time when I link to another page.
We have an applet that has to support the SUN VMs as well as the MS VM. The applet receives updates from a server (via tcp or http) and wraps them up as objects and passes them using the JSObject scripting context to a javascript function.
This function takes the object and reads the properties and updates a screen.
All seems simple stuff. The problem is that the MS JVM runs like a rocket, but the sun vm seems to max out our processor and also takes ages to process anything.
I have tried logging from the console using debug level 5, and it shows a lot of back and forth between the applet and the javascript when accessing methods on the object passed.
Seeing that as a possible problem, I now pass a delimited string to the front end, and then convert that into an update message purely in javascript so there is only one hit to the applet per message.
I am still seeing a massive difference between the sun and ms VMs.
Has anyone ever come across this, and is there anything I can do to help flatten out this performance?
Might there be a way to add a set of Javascript functions to a display page's existing set of Javascript functions on the fly without reloading the display page, and if so, how?
A couple of approaches I have tried, but without success are:
- A) For an embedded "retriever" IFrame in the display page to retrieve a set of JS functions from the server and then on its "onload" transfer (by innerHTML transference) that set of functions into the parent display page.
- B) Similiar to "A" but to use regular old browser frames - one being the "retriever" and one being the display page.
- C) Using a JS function in the display page to make a http request for a supplementary .js file(s).
Please note: the goal is to retrieve *only* an additional set of Javascript functions from the server, and then add them to an "original" set of functions already loaded into the browser. Meaning, NOT - say - for an IFrame to download from the server *both* the additional set and again the "original" set, which the parent display page could then run directly from the IFrame.
After "A", "B", and "C", I'm at a loss for further ideas.
But what I also want is, when someone clicks on the "Save" button, to first execute the "TestImage" function, and then the "SaveImage" function. Anyone know how I can do this?
Just wanted to share two handy RegEx expressions to strips leading and trailing white-space from a string, and to replace all repeated spaces, newlines and tabs with a single space.
* JavaScript example:
String.prototype.trim = function() { // Strip leading and trailing white-space return this.replace(/^s*|s*$/g, ""); }
String.prototype.normalize_space = function() { // Replace repeated spaces, newlines and tabs with a single space return this.replace(/^s*|s(?=s)|s*$/g, ""); }
" one two three ".trim(); // --> "one two three" " one two three ".normalize_space(); // --> "one two three"
i am having trouble understanding what the difference is between BLUR and FOCUS. I need to include these functions in my form and i am unsure what these features do and how i incorporate these into my form.
Are there javascript functions to find the cursor position of a mouse? Also, are there javascript functions to find if the mouse cursor is within a listbox? A C# code sample is shown below:
Listbox lb; //lb is a listbox Point cpos = lb.PointToClient(Cursor.Position); //find coordinates of mouse if(lb.ClientRectangle.Contains(cpos)) //if mouse cursor is within the listbox
Are there any javascript functions which can do the same as the above c# methods?
I want to learn more about creating functions for element events without having to put onclick event in every tag. For example:
<script> document.getElementsByTagName('input').onclick = function () { alert('hello'); } </script>
Now, I know the above does not work as I have tried it but hopefully the idea of what I am trying to achieve here. Basically for every input tag, when the user triggers the event (click) it will do the same function.
Anyway, I would more so like to learn about this type of scripting where you assign functions to events. However, I dont know what to search for in google and the like. Where could I learn more about this?
Looking at the code, you might assume (as I did) that clicking the button on page1.htm would load page2.htm. However for some reason, when calling a parent function, the function runs with the calling file's path rather than the path of the parent.
So it is actually trying to load /files/files/page2.htm! How do I force all calls to parent.function() to run with parent.hta's path as the root?
Realize that this is a simplistic example and simple solutions such as putting all the files in the same path, or dropping the "/files" in the loadPage2() function are not valid solutions.
Essentially I need to call parent.loadPage2() and have it run the function with the root path = parent.hta's path.
I have several form in my site, that validate on onsubmit.I call all the validation functions from a file call functions.js.Here is a sample of the code that is working:
I'm trying to make a web page with tabs which you can navigate between without the page reloading. I have one set of tabs working great, but when I add nested tabs there is a problem with the 'visibility' not being inherited and some parts stay visible in the sub-tabs. Sorry if this is unclear.
Here's how I have it layed out: I have a <span> for each content section of a tab. Then I have do the same thing for the content of each inner tab. When a tab is pressed some javascript code goes through and makes all content sections hidden and the content section for the tab that was pressed visible. If I select a tab and then select an inner tab it looks like is should, but when I try and select a different tab for the outer tabs the content for the inner section doesn't go away. I've found that this is because visibility is not inherited. My question is if anyone has a solution for this problem. I'm sure there is somebody that knows of some javascript trickery to do this.
This code uses a nested IF statement to put a pack of cards into an array of records. But for some reason the cards arn't going in.. like.. at all? I've put a document.write piece of code at end to display the card in the first slot and [object Object] appears? Code:
I'm a greenhorn in SVG and javascripting but I'm learning by doing. So, here my current problem question :
I have a svg document embedded in another svg document. I whant, through functions in an external javascript file, manipulate objects in either the child svg document or the parent document. How do I get access to elements of the other document ?
Example : I have a document "A" containing X/Y - Axis and included another svg document "B" with the graphs.
I whant now, as soon as the mouse cursor is over a graph in document "B" the belonging lable which is located in the parent svg document "A" to change color or size.
Or I whant the graph in "B" to start blinking as soon as the mouse is over the lable in "A".
I don't know how cross document borders.
Can anyone give me a short exapmle to get me going?
i have a nested loop in Javascript and i have a break statement in inner loop. As break statement takes control come out of inner loop. I want to come out of both loops if break statement reaches in inner loop. is there any way to do that ??
