Why Won't Print When Have Named The Function And Have A Variable In The Parameter
Aug 1, 2010
Code JavaScript:
var cookies="cookies_and_cookies_cookies_cookies"
var blah_blah_blah="whatever"
function reallycool(cookies){
document.write("whatever you like to do" +cookies);
}
what this won't print when I have named the function and have a variable in the parameter and I can't see any errors in the syntax ?
I have a JSON array data.cells that I need to iterate through to get the values out of and put the values into an onclick event listener.
Right now the variable name data.cells[i].letter is being based through the buildString function for each cell in my board, instead of the value of the variable. Same goes for the x and y variables.
I have a javascript will a) look for a certain value in a drop down box and b) depending on what value is selected open up a div that includes link that when moused over will pop up with an alert box contain the passed parameter. A couple problems with this, one is I am not as sharp on Javascript as I am on PHP, and two, when I manually place a value into the function parameter, if it's a number it works fine, but if its a string or word, it comes up with an undefined error. why the undefined error is coming up only on strings or words?
a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
I've recently started developing javascript using jQuery and so far I'm really enjoying it.Being a professional programmer (mainly C, C++, java and python) there is one thing that's been puzzling me regarding variable scope and unnamed function declarations. Let me exemplify:
------------------------ var sum = 0; $(xmlobj).find("item").each(function(){
i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a> <a href="link.com?page=text2">text 2</a> <a href="link.com?page=text3">text 3</a> etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page"; so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Code:I am having problems with the following. I am wanting to hide <tr> in my table (employees) and only show employees that are in the selected department (selected via dropdown box).I need to set a javascript array to a php array. I am looping and assigning the array and am wanting to pass a javascript variable as the index in php array. I have marked my problem lines in red. Thanx for any help.
<script type="text/javascript" > function display_elements() { var departments = new Array;
I am looking for a push in the right direction for a few problems i am running into; my first problem is I have to create a script element that contains the function amountTotal which should return the sum of all the values in the amount array. There are no parameters for this function, and I have to add the following commands to it.
1. declare a variable named total with an initial value of 0
2. create a for loop thatloops through all of the values in the amount array, at each iteration of the loop, add the current value of the array item to the value of the total variable.
3. and after the for loop is completed, return the value of the total variable.
The amount array has already been created and populated in a list.js file, I had to first create a script element pointing to it.
This is what i had for my link to the list.js file and funtion :
I have my entire code written but i am trying to break it up and fix my problems 1 at a time: when i open the code, it does'nt display correctly ( which is another problem) but I ran the debugger and it says my total is undefined. ( this is in another section of my code), but I guess my function is wrong somewhere.
I've been using jQuery for some time now but this is the first time I've run into something odd. Currently I'm developing a Theme for Concrete5.4.0.5, which automatically includes jQuery 1.4.2 - meaning, I can't use any other version of jQuery, that said: here is my problem.
I've got the following HTML (heavily simplified): <nav id="mainNav"> <ul> <li>Home</li> <li>Text <ul> <li>Subnav</li> </ul></li> <li>Text <ul><li>Subnav</li> </ul></li> </ul></nav> <section id="contentWrapper"> ... </section> And the following JS-jQuery Code (original, not simplified): function hoehenAngleichen(){ if($('#mainNav').height() > $('#contentWrapper').height()){ $('#contentWrapper').height($('#mainNav').height()); }} $(window).load(hoehenAngleichen); /* works fine until here */ $('#mainNav li').bind('onmouseover onmouseout', hoehenAngleichen); //will not trigger
I want the "hoehenAngleichen" function to be triggered whenever someone is hovering or leaving a li-Element. But this code seems not to bind the events with the named function properly.
I've been staring at this same problem for over a week now. I've worked around it as best as i can but i think it's time to ask someone else for input.
I'm trying to pass a value thru an ajax parameter.. that's all. it SHOULD be easy in theory.
What i want to do is create a jscript variable then pass that variable as the value for a parameter.
Php then converts that value to something it can use to finish the rest of my code.
As i said it's hindering my webpage progress and i would like to get it fixed soon.
I have just started learning JQuery and have a doubt in the below code. $.get('myhtmlpage.html', myCallBack);The doubt is should the 1st parameter of the get function be a HTML file or can it be a unction name?
I want to call java function in javascript.In which we pass one parameter to function and its returns String value which I want to display in alert message.
Captions for the images are called from the parameters of the main function and delivered into a span or div tag with the appropriate id. A very important part of what needs to be in the captions is text compiled by a separate function, in the project library.I've tried this with and without curly, square and round brackets, with and without semicolons and quotes- all with varying results. Sometimes the function is called, but it appears at the very top of the page and nowhere near the proper <span> tag.
addImage(a,b,c,d); // filename, image name and caption are in a, b and c. // d is the variable where I need to write my other function... addRef(t,s); // I need to put addRef in the d parameter of addImage.
I have a simple JS function that I want to return a true or false value based on the parameter passed in. At this point of time I receive the error "'True' is undefined". Here is my code below.
onclick="ShowSpecifiedPeriod(<%If bShowPeriod = false then Response.Write true else Response.Write false%>)"
The ASP variable bShowPeriod is set based on the hidden form field "ShowPeriod" and the initial value is set to false.
More than likely this has to do with the boolean Parameter but I am not sure how to handle this in JS. I have tried the following but receive the same results.
function ShowSpecifiedPeriod(boolean pShowPeriod) - Same Error function ShowSpecifiedPeriod(pShowPeriod boolean) - Same Error
I have an XML string which I want to pass to a java script function, where I am displaying that in different window with use of 'window.open()' method, but it is giving error.
I'm adding buttons to my google map through a loop. I pass some parameters, and the addButtons() function creates the buttons. How can I pass the "task" for the button to the function? In the addDomListener line below, I'm now writing the function name literally, I'd like find a way with a parameter.
// The loop... for (i=0;i<=4;i++) { oCC = addButtons(aCtrls[i],'btnContainerChild');
I've been searching now for quite a while trying to look for a way to give the default value to a function argument if it's not given. For example, in php one would do the follow:
function func_name(foo = 'default') { ... }
In the above case, if foo isn't supplied while calling for the function, then foo would default to 'default'. I have tried that in javascript, but it doesn't appear to be working, so I am wondering how should I do this in javascript?
I have been asked to include a print function in my program so that it works once i have finished the program, the function works at the start of the program but disapears when its finished i dont know where i have went wrong:
