Actionscript 将字符串转换为整数

Question

I am using Actionscript 2.0

In a Brand new Scene. My only bit of code is:

    trace(int('04755'));
    trace(int('04812'));

Results in:

• 2541

• 4812

Any idea what I am doing wrong/silly?

By the way, I am getting this source number from XML, where it already has the leading 0. Also, this works perfect in Actionscript 3.

Answer 1

In AS3, you can try:

parseInt('04755', 10)

10 above is the radix .

Answer 2

parseInt(yourString);

...is the correct answer. .parseInt() is a top-level function.

Answer 3

Converting a string with a leading 0 to a Number in ActionScript 2 assumes that the number you want is octal . Give this function I've made for you a try:

var val:String = '00010';

function parse(str:String):Number
{
    for(var i = 0; i < str.length; i++)
    {
        var c:String = str.charAt(i);
        if(c != "0") break;
    }

    return Number(str.substr(i));
}

trace(parse(val)); // 10
trace(parse(val) + 10); // 20

Basically what you want to do now is just wrap your string in the above parse() function, instead of int() or Number() as you would typically.

Answer 4

Bit of a simple one...

try this -

temp="120";
temp2="140";
temp3=int ( temp );
temp4=int ( temp2 );
temp5=temp4+temp3;
trace(temp5);

so, all you need is...

int("190");
