分裂不起作用

Question

我如何拆分十进制数？变量bidnumber是10.70.

var bidnumber = $(this).parent('div').siblings('.advert-details').find('tr:eq(3)').find('.advert-details-col-2').attr('data-bid');
bidnumber.toString().split('.');
var first = bidnumber[0];
var second = bidnumber[1];
alert(bidnumber[0]);
second.substr(0, 1);
var finalnumber = first + '.' + second;

当我发出警报时bid[0],它应该发出警报10..而是1提醒.我不知道我哪里出错了？

你忘了从split函数返回数组:

bidnumber = bidnumber.toString().split('.');
