【问题描述】：

我想在我的 html 中显示当天的实际约会。我想用 javascript 来实现它，在其中我可以从 Excel 表中获取约会的名称和日期。 我已经写了一些东西，但它不起作用，而且不是我想要的方式。 代码：

function appointment() 

    var event = [];
    var temp = [];

    event[0] = ["17.12.2015", "test1"];
    event[1] = ["11.12.2015", "TestToday"];

    var datum = new Date();     
    var today = today.getDate();    
    var month = today.getMonth() + 1; 

    for (i = 0; i < event.length; i++) 
        if (event[i]) 
            if (event[i][0] == today && event[i][0] == month) 
                event[i][0] = temp[i];
            
        
        else 
            break;
        
    

    if (temp.length == 0) 
        document.write("Today is nothing to do");
    
    else 
        var x2 = "Today " + ((temp.length == 1) ? "is following event: " : "are following events: ");
        for (i = 0; i < temp.length; i++) 
            x2 += ((temp[i] > 0) ? ((temp[i] == (temp.length - 1)) ? " and " : ", ") : " ") + temp[event[1]][3] + "(" + temp[event[i]][2] + ")";
        
        document.write(x2 + " appointment");
    

问题：我怎样才能让它工作？如何从 Excel 表格中读取约会主题和日期？

【参考方案1】：

问题在于您的 for 循环。比较今天的日期应该是dd.mm.yy 格式，因为它在数组中：

var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!

var yyyy = today.getFullYear();
if(dd<10)
    dd='0'+dd;

if(mm<10)
    mm='0'+mm;

var today = dd+'.'+mm+'.'+yyyy;

for (i = 0; i < event.length; i++) 
    if (event[i]) 
        if (event[i][0] == today) 
            temp[i] = event[i][0];
        
    
    // Don't break your for loop

Working Fiddle

【参考方案2】：

将您的代码更改为

var datum = new Date().setHours(0,0,0,0);
//you don't need today and month
if (event[i]) 
   eventDate = new Date(event[i][0].split(".").reverse()).getTime();
   if (datum === eventDate) 
        temp.push(event[i][1]); //there was a problem here as well
   

else 
   break;
