i use split function
string = data.con_loop[i].split("\.");
string input is “0.9.L” when i check
if(string[2]=="L")
it doesn’t into statement in scope of if Why?
You don’t need double slashes, then use equals to check
string = data.con_loop[i].split(".");
if(string[2].equals("L")) {
//.....
}
I have a javascript error that occurs on my site, Im pretty sure I know why, but I dont know how to fix it!
here’s the error:
Uncaught TypeError: Cannot call method 'split' of null
Here’s my JS code:
$(function(e) {
if (document.cookie.indexOf("login") >= 0) {
$("a#loggedInUser").html( $.cookie("login").split("|")[0] );
}
});
I’m just trying to display the username stored in the “login” cookie. Now, im pretty sure the error is because the value returned sometimes isn’t a string, then it doesn’t have the split method, so it causes this error.
How can I fix that? Any ideas?
Thanks!
Well you can do something like this to set a default if the value is null.
var login = $.cookie("login") || "";
$("a#loggedInUser").html(login);
Also, if you do that you might not need the document.cookie.indexOf thing.
Check the length of the cookie. This way you validate two things at once.
if (document.cookie.indexOf("login") >= 0 && $.cookie("login").length) {
$("a#loggedInUser").html( $.cookie("login").split("|")[0] );
}
I have a for loop that cycles through the number of elements that the user has created. There are a lot of available settings in this plugin, and each element can receive it’s specific settings.
User settings are entered in the following format: speed_x: “1000,500 > 1000,200 > 0,0”
This controls the speed_x in/out for 3 separate elements. The > divides by object and the commas separate the in/out.
So I can grab specific object speed_x values, I’ve split speed_x into speed_x_set (splitting by >) resulting in:
1 1000,500
2 1000,200
3 0,0`
3 Inside the loop, I grab the value by index (since it’s the object #) and split it by comma (to get speed_x_in and speed_x_out.)
for(var i=0; i<OS.numberofobjects; ++i){
OS.speed_x_on_set[i]=speed_x_set[i].split(",")[0],
OS.speed_x_off_set[i]=speed_x_set[i].split(",")[1],
...
};
Everything is assigned by object and by setting in/out correctly into the master OS settings object. T*he problem is I have many, many settings which need to be split in this fashion…* for example: delay_x_set, speed_y_set, opacity_set, etc. Their names are all based on the default setting name, with “_set” added as shown above. Hopefully this provides enough information. Thanks!
I would say to cache the split result
for(var objindex=0; objindex<OS.numberofobjects; ++objindex){
var splits = speed_x_set[objindex].split(","); //Cache the split so its does not need to be done twice
OS.speed_x_on_set[objindex] = splits[0];
OS.speed_x_off_set[objindex] = splits[1];
...
};
let said I have an array that store like this.
Array (
[0] => width: 650px;border: 1px solid #000;
[1] => width: 100%;background: white;
[2] => width: 100%;background: black;
)
How should I make the array[0] string split into piece by separated the “;”? Then I want to save them in array again, or display them out. How should I do it?
Array(
[0] => width: 650px
[1] => border: 1px solid #000
)
Any idea? Thank in advanced
I would personally use the preg_split to get rid of that extra array element that would occur from the final semicolon…
$newarray = array();
foreach ($array as $i => $styles):
// Split the statement by any semicolons, no empty values in the array
$styles = preg_split("/;/", $styles, -1, PREG_SPLIT_NO_EMPTY);
// Add the semicolon back onto each part
foreach ($styles as $j => $style) $styles[$j] .= ";";
// Store those styles in a new array
$newarray[$i] = $styles;
endforeach;
Edit: Don’t add the semicolon to each line:
$newarray = array();
foreach ($array as $i => $styles):
// Split the statement by any semicolons, no empty values in the array
$newarray[$i] = preg_split("/;/", $styles, -1, PREG_SPLIT_NO_EMPTY);
endforeach;
Which should output:
Array(
[0] => width: 650px;
[1] => border: 1px solid #000;
)
Unlike explode, which should output:
Array(
[0] => width: 650px;
[1] => border: 1px solid #000;
[2] => ;
)
An example
foreach($array as $item) {
$mynewarray = explode(";",$item);
foreach($mynewarray as $newitem) {
$finalarray[] = $newitem.";";
}
//array is ready
}
