JavaScript - How To Make Javascript Variable Declaration Strict?
I've just discovered (through trial and error) that if a variable is assigned a value without first being declared, it automatically has global scope, even if it is assigned inside a function.
This is a pain in the butt because if you forget the var keyword, then suddenly ... whoops! You've got yourself a global variable! Is there any way that I can make javascript throw an exception if I fail to declare a variable before assigning a value to it? It would make things much easier, rather than having to hunt through increasingly complex functions to find that pesky unintentionally global variable. Similar TutorialsHi, I am fairly new at Javascript but have some ability - though I can't figure this one out. I need a JavaScipt "IF Statement" that validates that a Text Field is in the format of 2 Letters then 2 Numbers. The field also has to contain a total of 4 characters no matter what. For example, every entry for that Text Field has to be in the following format: AB34 I would sincerely appreciate anyones help! i am new to javascript and i can't seem to make it work for me to make a script that gets the current time on the browser and leaves a message for a certain time I can make 3 max variables by doing if, else if, else i need 4 variables so that i can make a background for the certain times for the current day time (morning, evening, afternoon, night) Thank you for listening (and/or helping me out) Is it possible to make a variable available to other functions outside a function So to make it global from within a function without using a callback Code: function() {
var something = 'hello';
}
function(something) {
document.write(something);
}
something like that possible?? Hi! I have a javascript in the head of the document which has a variable named "ref2" ... ref2 is already working as I can see its value working in another function. I need to send this variable as the value of a hidden field in the form which is in the body of the document. This is my JavaScript Code: Code: function WriteContactFormStatement1 () {
var ContactFormValue = ref2;
document.write('<input type="hidden" name="UReferrersName" value="' + ContactFormValue + '" />');
}
var WriteContactFormStatement = WriteContactFormStatement1 ();
And at the end of my form, before the submit button, I have the following code: Code: <!-- START -- Javascript to print the statement for UReferrersName --> <script language="JavaScript" type="text/JavaScript"> //WriteContactFormStatement(); document.write (WriteContactFormStatement); </script> <!-- End -- Javascript to print the statement for UReferrersName --> When I execute the form, it doesn't work the way it should, plus, gives me a word "undefined" next to the "Submit" button ..... Please help !... - Xeirus. I've been looking all over for an explanation of this function declaration but cant find it. Can someone answer what it means to have a function with no name, just declared as this. When does it execute? How does it get called? !function() { /* all the code in here omitted*/ } (); For reference, here's the function: !function () { var b = document.documentElement, c = "DOMControl_placeholder"; var a = function (d) { var g; var d = d || window.event, e = d.target || d.srcElement, f = e.getAttribute("placeholder"); if (f) { if ("focus" == d.type || "focusin" == d.type) { if (e.value == f) { e.value = ""; CSS.removeClass(e, c); } } else if (e.value == "") { CSS.addClass(e, c); e.value = f; } if (e.value == "" || e.value == f) { g = e.parentNode; CSS.addClass(g, "xyz"); CSS.removeClass(g, "xyz"); } } }; b.onfocusin = b.onfocusout = a; if (b.addEventListener) { b.addEventListener("focus", a, true); b.addEventListener("blur", a, true); } }(); Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hello I have a piece of javascrip that refreshes the page: ---------- Code: <script type="text/javascript">
<!-- Begin
function reFresh() {
location.reload(true)
}
/* Set the number below to the amount of delay, in milliseconds,
you want between page reloads: 1 minute = 60000 milliseconds.
2 minutes = 120000 milliseconds 5 minutes = 300000 milliseconds*/
window.setInterval("reFresh()",20000);
// End -->
</script>
-------- I am new to javascript and wanted to use an html options menu in order to be able to choose the refresh interval: Code: <SELECT NAME="refreshtime"> <OPTION VALUE="60000">1 min</option> <OPTION VALUE="120000">2 min</option> <OPTION VALUE="180000">3 min</option> <OPTION VALUE="240000">4 min</option> </SELECT> I know that I have to pass a variable to the function. I have tried several variations but none have worked. I have mostly received a "done with errors" warning. Any help would be appreciated. Thanks Zam I have the following code which attaches a function to events in x number of comboboxes (x will probably always = 4, but I do not want to hard-code this). I wish to pass the value of i to the function being attached as well as the value of tempData. In other words, I want the parameters in function to be the value, not a reference variable. In the current example, I am using the hard-coded variable ci. This I want to be replaced by a literal created when the event handler is attached (the value of the loop variable i). Also, notice that I get the filter value in the event handler (assigned to the variable ct). I would like to replace this code with the value of tempData which would also be determined when the evenet is attached (it is the same value in this case, but it keeps the onChange event from having to do this each time it runs). Code: var props = {
col_0: "select",
col_1: "select",
col_2: "select",
col_3: "select",
btn_reset:true,
display_all_text: "-Show All-",
on_filters_loaded: function(o){
//reset all filters
var slcIndexes = o.GetFiltersByType(o.fltTypeSlc, true); //o.fltTypeSlc = 'select'
for(var i=0; i<slcIndexes.length; i++){
//this public method returns a filter DOM element by column index
var slcElm = o.GetFilterElement(slcIndexes[i]);
//tempData = slcElm.options[slcElm.selectedIndex].text;
//window.alert(tempData + " " + slcElm);
tf_AddEvent(slcElm, 'change', onchangeFn=function(){
//ci is the column index for the column to filter on. ct is the new text from the combobox to filter on
var ci;
ci = 2;
var ct = tf_outputTable.GetFilterValue(ci);
tf_outputTable.ClearFilters();
//window.alert("ci= " + ci + " ct= " + ct);
tf_outputTable.SetFilterValue(ci, ct);
tf_outputTable.Filter();
}); //end tf_AddEvent
}
}
}
setFilterGrid("outputTable",props);
I've been going through this great tutorial on how to implement a type-ahead feature on a text field and there's something which hopefully you guys can explain. On the third page there is this function. Code: AutoSuggestControl.prototype.init = function () {
var oThis = this;
this.textbox.onkeyup = function (oEvent) {
if (!oEvent) {
oEvent = window.event;
}
oThis.handleKeyUp(oEvent);
};
};
What I don't understand is this line: this.textbox.onkeyup = function (oEvent) { I know about anonymous functions, but I don't know where the value for the parameter oEvent is going to come from. Can someone explain this? Thanks! :) I have a script that clicks links how can i make it not click a certain. Such as how to make it dont click red link or dont click bold links.

Thank you very much. Hi! frnds, I was wondering if you could help me with the JavaScript programing... Every possible help will be appreciated I am very new to the world of programming and JavaScript but I have some Ideas which I would like to execute and I will learn anything and everything in the way to accomplish them... Program: user end: the page is about users priorities and displaying back the selected... the program work as a user reaction based comparison module... where the priorities stored in the program are shown 2 at a time and lets user to select what is more important to him and stores the result in another variable than that variable is shown with another variable which is already stored and the result out of that is stored in another new variable and so on.. in the end it show the result of important selected priorities... 1) say there are 6 variables storing string values: Code: <script type = "text/javascript"> var p1 = "Doctors appointment"; var p2 = "studying for the exam"; var p3 = "Going out for most awaited shopping"; var p4 = "Login on Facebook"; var p5 = "Replying to text msgs"; var p6 = "Go out with friends"; 2) there are two sections on the html document: i) where the variables are displayed dynamically and changes the value on click.. it works like a comparison where user selects (onclick) what is more important to him shows the next value and so on... in the end stores the result... functioning(I have no I idea how to do this): say on the html document only two variables are displayed at first and than the user selects one of it as more important to him so the result is stored in another new variable than that new variable is shown with the third stored variable and once one of them is selected it is stored in another new variable and is compared with forth stored variable and so on till the last selected is stored as the result1... all comparisons must happen on the same div of the html document procedure has to loop three times till 3 results (result1, result2, result3) out of six are selected more important... result1 has to be removed from the next loop for result 2 as result1 is already selected important by the user.. result1 and result2 are to be removed from the next loop for result 3 as they are already selected important by the user ii) the second section displays important 3 results (result1, result2, result3) selected by him... my friend told jQuery can do the dynamic comparison part but I don't know how to use it... the logic of creating new variable for storing result and then comparing can be improved or changed... Please help Hi all, I've been trying to build a form with dynamic checkboxes. I'd like to have a master 'select none' checkbox in a few form fields which has 2 key functions:- 1) clearing all field boxes the user may have entered before opting to select none 2) disabling all field options to make it impossible for the user to tick both 'none' and other options. This 'select none' checkbox should be ticked by default, so when the user unchecks it, the rest of the field options light up. I'm a complete novice but I have it working ok having stitched a few pieces of code I've found together, however I don't think it's very efficient. I have had to duplicate both bits of the javascript to make it work, changing only the function names in the <head> area ('Uncheck' and 'Uncheck2') and the class variables in the form in the <body> area ('fruit_child' and 'veg_child'). As this form will have several more fields eventually, I'm looking for a better way to do this while maintaining the functionality. Ive read bits about object-orientated programming which may be what I'm looking for to make this more efficient, but I'm not sure how to implement it in this example. Can a more experienced coder please help? Kind thanks, Fleef Code: <head>
<SCRIPT LANGUAGE="JavaScript">
// Check_ctr: clears all when 'none' box ticked -->
function Uncheck(chk)
{
if(document.myform.Check_ctr.checked==true){
for (i = 0; i < chk.length; i++)
chk[i].checked = false ;
}
}
// End -->
</script>
<SCRIPT LANGUAGE="JavaScript">
// Check_ctr: clears all when 'none' box ticked -->
function Uncheck2(chk_veg)

if(document.myform.Check_ctr_veg.checked==true){

chk_veg[i].checked = false ;
}

I heard that when we put javascript in website, then site takes time to open, is it correct ? If yes then which script is good for website.
Hi, well earlier i asked for a script which can load game which showing some banner until the game is loading and the load progress that it shows, it shouldn't be fake, many people said you need flash for it, but atlast i found a script that can do that for me. BUT there is a issue when i started using the script in the script the width and height can be in px like width 500 but it can't be made to width 100% when i make it 100% the script stops working. I can't use px or any other thing except 100% as i want the flash to increase its width and height with the change in screen resolution. Here is the script, you can make a demo html file out of it for testing purposes, if you don't want to make one i am ready to provide a demo page too, please leave a comment for it.

in the above code the 640 width and height is the issue, as it doesn't work with 100% values, i was wondering how to make it work with 100% width and height. I don't know what did i miss or where did i go wrong? Hey everyone. I need a little help and I'm not an expert by any stretch of the imagination with javascript. I have a simple little code script and I'd like either the onClick function (or the entire code itself, whichever is easiest) to only load once every 24 hours for each IP address. So "123.1.22.333" should only get the effect of this code once every 24 hours regardless if they revisit my site 5 times a day let's say. So here's my little script: Code: <script language="JavaScript">
function goNewWin() {
TheNewWin=window.open("http://google.com",'Google','toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1');
TheNewWin.blur();
}
</script>
<body onClick="goNewWin()">
Any help would be very appreciated. Thanks! |
