将浮点数转换为时间格式？

Question

Is there a way to convert float number to time format using html? For example if you have number 8.5 , it would output 08:30 ?

I have something like this:

<p><strong>${object.some_time}<strong></p> <!-- So this outputs that number --> 

And I get this output:

8.5

But I would like to get this output:

08:30

Update I tried this:

<p><strong>${object.some_time // 1}:${object.some_time % 1 * 60}<strong></p>

Then it outputs this:

8.0:30.0 If I put int() around either calculation, I don't get any output. So I think I can't for some reason convert types..

Answer 1

Maybe try this way :

• cut the hours as you already do
• then do 60*minutes (here 0.5) and parseInt()

This should sove your probem

Answer 2

option 1: add a functional field which convert the float value to time string. Then use the functional field in your html.

option 2: create a method to convert the float to time string. Then call the function from your html code. option 3: i havent tried this.

${int(object.some_time // 1)}:${int(object.some_time % 1 * 60)}

Answer 3

You can use following method to convert the float to time string.

function get_time_string(sometime) {
            currentHours =some_time // 1;
            currentMinutes = int(object.some_time % 1 * 60);
            if(currentHours <= 9){ 
                currentHours = "0" + currentHours;
                }
            if(currentMinutes <= 9) {
                 currentMinutes = "0" + currentMinutes;
                 }
            return currentHours+":"+currentMinutes;
        }
