Javascript拆分了一个字符串并删除了前导0

Question

I am very new at jquery...how would I split a strings like this:

readybuilt-ANT-133.pdf
readybuilt-VIC-041.pdf

so I get just the numbers 133 and 41

this what I tried thus far

var str = this.home_pdf;
          var res = str.split("-");
          var lotNumber = res[2].split(".");
          lotNumber = lotNumber[0];
          console.log(lotNumber);

this works well, but how would I remove the leading 0s?

Answer 1

Try parseInt ( lotNumber, 10 ) . It will not care about leading zeroes when given an appropiate radix parameter.

PS: obviously, regex is the way to go here.

A much better way is to use Bergi's method

var str = "readybuilt-VIC-041.pdf";
var lotNumber = str.split(/\.|-0*/)[2];
console.log( lotNumber );

Answer 2

Parse the variable as an integer:

lotNumber = lotNumber[0];
lotNumber = parseInt(lotNumber,10);
console.log(lotNumber);

Answer 3

assuming that this.home_pdf contains the string, this should do the trick:

var str = this.home_pdf;
str=parseInt(str.replace(/\D/g,''));
if(str.match(/^0/g)){
    str=parseInt(str.replace(/0/,''));
    }

Answer 4

Yet another solution, using match()

'readybuilt-ANT-133.pdf'.match(/(?=[1-9])([0-9]+)/g);    // 133
'readybuilt-VIC-041.pdf'.match(/(?=[1-9])([0-9]+)/g);    // 41
