JavaScript - I Can’t Pass Properties To Function
Similar TutorialsI'm still learning js core using Flanagan's 5th ed. so please bear with me; is the if ("ignore" in arguments.callee) return; below valid or a typeo? Thanks J. Code: function inspect(inspector, title) {
var expression, result;
// You can use a breakpoint to turn off subsequent breakpoints by
// creating a property named "ignore" on this function.
if ("ignore" in arguments.callee) return;
.......
Hi, Can anyone tell me How to send values from application resources.properties file to a java script function in a jsp Thanks in Advance, John Ven Hello again! Is there any way to pass a function(with its parameters) to another function using a parameter?

Hi all 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. Thank you.. Code: // The loop...
for (i=0;i<=4;i++) {
oCC = addButtons(aCtrls[i],'btnContainerChild');
...
}
// The function...
function addButtons(cButtonID,cClassName) {
var oButton = document.createElement('DIV');
oButton.className=cClassName;
oButton.id=cButtonID;
//... other settings here...
// ===> Here, I'd like to set the click function through a parameter
google.maps.event.addDomListener(oButton, 'click', function()
{gmapSetCenter(defaultCenter)});
Hi all, I need to pass a variable to an inner function and I got it to work but: (1) I don't know why it works (2) I don't know if it's right or optimal So, please look and comment: Code: for (var h = 1.0; h <= 3.0; h += 0.5) {
ed.settings.formats['spacing' + String(h.toFixed(1))] = {
'block' : 'p',
'styles' : {
'marginBottom' : String((h - 1).toFixed(1)) + 'em'
}
}
h = (function (h) {
c.onRenderMenu.add(function (c, m) {
m.add({
'title': String(h.toFixed(1)),
'caption' : 'Set the line spacing to ' + String(h.toFixed(1)),
'onclick': function () {
ed.formatter.apply('spacing' + this.title);
return false;
}
}).setDisabled(false);
});
return h;
})(h);
};
You can ignore a lot of the code as it doesn't factor into the question... and I know that re-ordering the code can eliminate my problem (but I can't re-order it because defining the formats MUST come before "renderMenu" or else it doesn't work - and I don't want to use two loops - one to define the formats and another to define the menu). The part that's freaking me out is this: Code: h = (function (h) {
c.onRenderMenu.add(function (c, m) {
m.add({
'title': String(h.toFixed(1)),
'caption' : 'Set the line spacing to ' + String(h.toFixed(1)),
'onclick': function () {
ed.formatter.apply('spacing' + this.title);
return false;
}
}).setDisabled(false);
});
return h;
})(h);
See the strange things I have to do to get h inside of c.onRenderMenu.add()? Is this right? Can I do it any "better" or more correctly? Thanks! -- Roger I have a php script which dynamically creates a table containing text boxes with variable names. Example: Code: echo '<td align="center" bgcolor="'.$bgcolor.'"><input type="text" name="payable_'.$key.'" id="payable_'.$key.'" value="'.$payable.'" size="3" maxlength="4" /></td> '; In the above instance the text box name might be 'payable_23323'. I need to code an onKeyUp event which sends the text box name to a function, and in that function I need to retrieve the text box name and the string after 'payable_' together with the value the user has input into the text box. Any help is greatly appreciated . . . I have been Googling this for hours to no avail - probably because I don't know what to search for . . . Thanks hi guys! i have a problem in passing the variable to function ,the variable which is used in<td> as table data. Code: <td onmouseover="todayevent(somevarible);" onmouseout="hideevent(somevarible);" >' + somevarible+ '</td> i want to pass somevariable by function todayevent(). how can i do this. plz help me someone. Here's something that I tested without the PHP and it worked ok. Now that I've introduced the PHP to the document it doesn't work. The PHP variable is not passing to Javascript properly. By use of some cleverly placed alert boxes, I figured out that the only thing that is getting passed forward is something called : "object HTML ImageElement" Specifically, I assign the element ID the unique ID number of the record in the SQL database. The problem isn't with the ID numbers themselves: They are alphanumeric and unique. I think it boils down to one of two lines of code. Either this isn't working (about line 12) Code: function expander(RecordID){
or perhaps it is when I am calling the function (about line 66): Code: echo "<img id='".$row['IDNumber']."' src=".$row['ImagePath']." width='5%' onMouseOver='expander(".$row['IDNumber'].");' onMouseOut='shrinker(".$row['IDNumber'].");'>";}
The PHP works (I can get the images to appear, so the connection to SQL and such isn't a problem). I am sure most of the JavaScript is good, too, as I said I had it all working prior to dropping in the PHP. Since I am not going from JavaScript to PHP I don't think I need AJAX. I just need the PHP to pass to JavaScript. Any ideas? Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"

who i can put my php variable into the funtion? Thanx in advence and sorry for my bad english! hello, only just starting using javascript, so question may not make sense but il try anyway. if i group some javascript into a function that returns false; how could i carry that 'false' out of the function so it can be used outside the function. the example below shows the validate function checks for a condition then returns false if it is met. i want this false to then be passed out of the function to then throw an error in its containing function. (goal to prevent the submitting of a form) if (checBox =="1"){ validate(); } function proceed(); function validate() { if (chilD1.value >70) { alert("Please enter your Childs correct Age"); return false; chilD1.focus(); } } i dont want the proceed function to be called, so how can the other function prevent this. Now i realise that the validate function could be incorporated into the top level function but, my form will eventually be quite large with a multiplitude of fields so i need to know how i can call back to functions and use them as objects insteasd of repeating lots of code. Hope you can help thanks. I HAVE BEEN TRYING TO FIGURE OUT THE PARAMETERS IN THE FUNCTIONS, INCLUDING THE ARRAYS [i], [p], ["get_" + i], ["set_" + i] AND HOW THE METHODS ARE BEING CALLED IN RELATION TO i, p and val, so that I can make sense of this code. If possible can you explain the code also What I will like to know are the properties and methods of the objects generated in the following code? Also I want to know how I can use those methods to show and change the name and age for the emp2 object. this is the code: function Employee(properties) { for (var i in properties) { if (properties.hasOwnProperty(i) && typeof properties[i] != 'function') { this["get_"+i] = (function(p) { return function() { return properties[p]; }; })(i); this["set_"+i] = (function(p) { return function(val) { properties[p] = val; }; })(i); } } } var emp1 = new Employee({ name: "Bob", age: 35, foo: function() {} }); var emp2 = new Employee({ name: "Gary", age: 54 }); hello all, I am new to javascript, i just wanted to know how can i send a array from perl to javascript function.... if anybody having any idea about this please reply me..thanks in adbvance How to: pass local variable from <head> JS function to <body> textarea I have a JS function in the head that calculates a variable. the function is triggered by the vevent of a button click. when calculation is done, how is it sent back to the page and placed in a textarea or textbox....?? /Beginner issues :/ Can someone help me to edit this code...?

All pages are run in IE 6.0. After I run debugger I've found out that on my page offsetLeft/Top clientHeight properties have some non-zero values. I have <span id="listCLient" style="width:200px;">..</span> and on my test page elListClient.clientHeight = 200, but on customer's app's page it is 0x0 ? Same with other offsetXXX properties etc. But elListClient.style.height bears correct value. I use those properties everywhere. I think it is some settings somewhere ? or CSS styles ? Can anyone help ? Thanks a lot Vladislav Hi, I want to a javascript function like showModalDialog(<page_name>,'','<options>') here in the option I need to have overlay property where I can set opacity values. Is there any solution? Please letme know Is there a way to circle trough the native properties (constructor, prototype, length) of an Array object? Obviously, a simple for(a in array) won't do the trick.
I have developped a script in order to resize the height of a div on a web page in order to display it at least up to the size of the window. Here is the code: function resize(){ var frame = document.getElementById("content"); var padding_top = parseInt(window.getComputedStyle(frame,null).getPropertyValue("padding-top")); var padding_bottom = parseInt(window.getComputedStyle(frame,null).getPropertyValue("padding-bottom")); var padding = padding_top + padding_bottom; var bodyheight = document.body.scrollHeight; var windowheight = window.innerHeight; if (bodyheight < windowheight){ frame.style.height = windowheight - padding + "px"; } } It works well, but I was wondering why I am not able to get the padding-top and -bottom using these two instructions: var padding_top = frame.style.paddingTop; var padding_bottom = frame.style.paddingBottom; The script runs but Firebug shows empty strings for both values. How come? Is there a bug in Firefox? Thanks inadvance for your time and help. |
