Js string to int (the difference between number and parseint)

<script>
var str= ' 1250 ';
Alert (number (str)); Get 1250

Alert (parseint (str)); Get 1250

var str1= ' 00100 ';

Alert (number (STR1)); Get 100

Alert (parseint (STR1)); Get 64

It is found that the parseint method is converted as a 2-in-10 binary method when the number beginning with format ' 00 ' is used, so it is recommended that string go int is best
