function changeWebsite() {
var currentTime = new Date().getHours();    

 if (7 <= currentTime&&currentTime < 18) {
       document.write('  <table id="Table_01" width="200" height="400" border="0" cellpadding="0" cellspacing="0">

}

changeWebsite();

错误在第 7 行 'document.write('

Answer 1

1. JavaScript 不支持多行字符串。

2. 字符串中有未转义的单引号(用单引号分隔)。
   例如，您必须更改:

   onmouseover="window.status='Visit My Biography Website'; 
   

   到:

   onmouseover="window.status=\'Visit My Biography Website\';
