layui.all.js:2 Uncaught Error: Syntax error, unrecognized expression

报错内容：

    layui.all.js:2 Uncaught Error: Syntax error, unrecognized expression: input[name="image1UploadTime"+language]

错误代码：

$('input[name="image'+j+'UploadTime'"+language]').val(currentDateTime);

因为  language 是个变量

修改为 

    $('input[name="image'+j+'UploadTime'+language+'"]').val(currentDateTime);
