I was trying:
Code:
<script>
function testtrim(value) {
alert(value.trim());
}
testtrim("Alex ");
</script>
The javascript don't work, my firebugs says:[value.trim is not a function] how to simulate an trim function?
for all your javascript trimming needs...
function trim(inputString) {
if (typeof inputString != "string") return inputString;
return inputString
//clear leading spaces and empty lines
.replace(/^(s|
|
)*((.|
|
)*?)(s|
|
)*$/g,"$2")
//take consecutive spaces down to one
.replace(/(s(?!(
|
))(?=s))+/g,"")
//take consecutive lines breaks down to one
.replace(/(
|
)+/g,"
")
//remove spacing at the beginning of a line
.replace(/(
|
)s/g,"$1")
//remove spacing at the end of a line
.replace(/s(
|
)/g,"$1");
}
I need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() {
if (Selection=="Select State")
alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.
I have no clue what is throwing this error. What am I missing?
I have jQuery auto tabs for the 'billboard' area. On active tab, I absolute position & z-index links over top the 'tabs' to link to the other pages in the site. The links work on all except IE6/7. IE6/7 link to the anchor fragments.
$(document).ready(function(){
I do an Alert of Data and its the next:
It works perfectly in Firefox and Chrome, but in IE 7/8 it doesnt do anything. In fact, in IE the inputs that I insert dinamically when I press the button " agregar" doesnt appear in the page, but they are there, because when then when i do the Insert I have all of that dinamyc inputs that I put. The problem is that they are not shown in the page.
Using Regular Expressions (JavaScript 1.2/JScript 4+) :
String.prototype.lTrim =
function()
{
return this.replace(/^s+/,'');
}
String.prototype.lTrim =
function()
{
return this.replace(/s+$/,'');
}
String.prototype.trim =
function()
{
return this.replace(/^s+|s+$/g,'');
}
or for all versions (trims characters ASCII<32 not true
"whitespace"):
function LTrim(str) {
for (var k=0; k<str.length && str.charAt(k)<=" " ; k++) ;
return str.substring(k,str.length);
}
function RTrim(str) {
for (var j=str.length-1; j>=0 && str.charAt(j)<=" " ; j--) ;
return str.substring(0,j+1);
}
function Trim(str) {
return LTrim(RTrim(str));
}

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'm trying to figure out how to invoke a method on an object given the
object and the method name. For example, here's a simple object with a
method:
function MyObj (pName, pDesc) {
this.name = pName;
this.desc = pDesc;
MyObj.prototype.foo = function() {
return this.name + " - " + this.desc;
}
}
and here is some sample code to manipulate it.
var o1 = new MyObj("nn", "dd");
var s1 = o1.foo();
The assignment to s1 invokes the foo method and gets back the string "nn -
dd" as expected. now I try to find the foo method by it's name:
var funcName = "foo";
var theFunc = o1[funcName];
var s2 = theFunc();
the assignment to s2 invokes the function OK, but not in the context of the
object. can someone tell me how to invoke a function as a method?
I've seen an other post talking about not being able to perform a .html().replace() also, but no one replied.
[URL]
Why is this? I ran into the same problem and from what I was seeing, the replace() was only replacing the very first match. My work around was pretty simple, I just keep running replace() until it was done, but I'm dumbfounded as to why this would need to be done.
while (newLastRow.html().indexOf(settings.placeholder) > -1){
newLastRow.html(newLastRow.html().replace(settings.placeholder, curTotal)); }
As with the other post, I'm dynamically adding html to the page using a template, where the replace() method is updating the IDs of the fields when adding a new instance.
What's special about the value returned by the html() method? Is there a different preferred way to do this?
Given the following HTML:
<ul>
<li class="">1</li>
<li>2</li>
<li>3</li>

Unfortunately that doesn't work. I understand that the index() isdocumentation (though confusing) correctly tells you that the above code doesn't work. Maybe I'm just weird, but I feel that the way .index() is implemented for string arguments is very counter intuitive. I have an expectation that .index() is similar to indexOf() in javascript.
I have to pass string entered in the input text to server method calling through jquery ajax. But its not going through.
[Code]....
I don't think this is "do-able" but thought I'd better check. Say I
want to replace certain names in some source code as long as they are
not properties (dot properties) of objects. I could use a regular
expression like:
rx = /(?:(.)|)(?:name1|name2|name3)/g;
map = [];
map["name1"] = "a";
map["name2"] = "b";
map["name3"] = "c";
source = source.replace(rx, function ($0, $1) {return $1?
$0:map[$0]});
Dot properties like .name1 are not replaced by anything new and they
need to be "skipped" over by this regular expression but other name1
identifiers need replacement with "a".
One problem with this approach is that dot properties like .name1 are
replaced by themselves and this is just unnecessary work. Something
like a "false" return to skip replacement would be nice but the
following doesn't work.
source = source.replace(rx, function ($0, $1) {return $1?
false:map[$0]});
There are other ways to get around this by using something else
besides replace() but I wanted to see if it could be done with the
replace() method.
i'd like to know if it's possible to send variables with the post method in a javascript instead of doing :

I am trying to call a java method from within my Javascript, but cannot
seem to get it to work. All the examples I have found online and in
the forums are using Java applets. I have a method that I want to call
that does a search, and produces a message dialog displaying the
results. Also, the class file lives next to the html file. How would
I invoke this in my code? This is what I have now:
<script>
function searchStrings(){
Searcher.search();
}
</script>
<form>
<input type="button" value="Search" onclick=searchStrings()>
</form>
A Java applet has two methods stop() and destroy() that get called when the user moves to a different page. Does javascript have anything similar?

Does anybody know how to turn off form actions please?
I have 2 types of users (members and non-members) using the same form action. This form has 4 buttons in total.
If the user is a member they have full access to all buttons.
If the user is a non-member they can only use 2 of the 4 buttons.
So, at the moment, when they are non-members and click on one of the members buttons, an OnClick event handler is added to the input type = "submit", which generates a new window with a document explaining to the user that they need to register.
There is no problem generating this window.
The problem is that the form specified in the form action still executes and the members page is still displayed.
So is it possible to turn off the form action in this instance so that the main page isn't refreshed/executed, or do I have to create different form actions for different users.
Surely there must be a way to prevent the form action from being triggered?
I realise I could simply not display the button for non-members, but I'd prefer to do so, as it allows them to see the features that members receive.

I'm working with SageCRM. When SageCRM outputs the company address, I kid you not, it outputs the value and then a crap ton of HTML non-breaking spaces, a break tag and then repeat for the other address lines.My client added a button to the page via the customization function that links over to MapQuest. But, all those non-breaking spaces mess up the URL.I'm trying to fix it, but I'm having some trouble and thought I'd throw it out to you all.
