将CSS类添加到div

我编写了这个脚本，但它只适用于我没有广告class="yes"，但如果iI添加它，它不会工作，这是什么原因。谢谢。

这工作：将CSS类添加到div

<script type="text/javascript"> 

    var d=new Date(); 
    var weekday=new Array(7); 
    weekday[0]="<div>Sunday</div>"; 
    weekday[1]="<div>Monday</div>"; 
    weekday[2]="<div>Tuesday</div>"; 
    weekday[3]="<div>Wednesday</div>"; 
    weekday[4]="<div>Thursday</div>"; 
    weekday[5]="<div>Friday</div>"; 
    weekday[6]="<div>Saturday</div>"; 

    document.write("Today is " + weekday[d.getDay()]); 

</script>

这不起作用

<script type="text/javascript"> 

    var d=new Date(); 
    var weekday=new Array(7); 
    weekday[0]="<div class="yes">Sunday</div>"; 
    weekday[1]="<div class="yes">Monday</div>"; 
    weekday[2]="<div class="yes">Tuesday</div>"; 
    weekday[3]="<div class="yes">Wednesday</div>"; 
    weekday[4]="<div class="yes">Thursday</div>"; 
    weekday[5]="<div class="yes">Friday</div>"; 
    weekday[6]="<div class="yes">Saturday</div>"; 

    document.write("Today is " + weekday[d.getDay()]); 

</script>

尝试单引号：

<script type="text/javascript"> 

    var d=new Date(); 
    var weekday=new Array(7); 
    weekday[0]="<div class='yes'>Sunday</div>"; 
    weekday[1]="<div class='yes'>Monday</div>"; 
    weekday[2]="<div class='yes'>Tuesday</div>"; 
    weekday[3]="<div class='yes'>Wednesday</div>"; 
    weekday[4]="<div class='yes'>Thursday</div>"; 
    weekday[5]="<div class='yes'>Friday</div>"; 
    weekday[6]="<div class='yes'>Saturday</div>"; 

    document.write("Today is " + weekday[d.getDay()]); 

</script>

你的双引号是打破字符串。更改

weekday[0]="<div class="yes">Sunday</div>";

到

weekday[0]="<div class='yes'>Sunday</div>";

你需要使用单引号：

weekday[0]="<div class='yes'>Sunday</div>";

如果你不这样做，你的字符串将是无效的，因为第一个String接受将是

"<div class="

然后t他休息不会被期望。

注意语法突出显示 - 双引号与字符串的起始和结尾双引号匹配。你需要转义：

<script type="text/javascript"> 

    var d = new Date(); 
    var weekday = new Array(7); 
    weekday[0] = "<div class=\"yes\">Sunday</div>"; 
    weekday[1] = "<div class=\"yes\">Monday</div>"; 
    weekday[2] = "<div class=\"yes\">Tuesday</div>"; 
    weekday[3] = "<div class=\"yes\">Wednesday</div>"; 
    weekday[4] = "<div class=\"yes\">Thursday</div>"; 
    weekday[5] = "<div class=\"yes\">Friday</div>"; 
    weekday[6] = "<div class=\"yes\">Saturday</div>"; 

    document.write("Today is " + weekday[d.getDay()]); 

</script>

哦，和可能更简单的方式来做到这一点：

<script type="text/javascript"> 
    document.write("Today is <div class=\"yes\">" + 
     ["Sun", "Mon", "Tues", "Wednes", "Thurs", "Fri", "Satur"][new Date().getDay()] + 
     "day</div>"); 
</script>
