如何在数组输出中添加换行符？

Question

var d0 = document.getElementById("d0").getElementsByTagName('h2');
var pp0 = document.getElementById("prepend0").getElementsByClassName('formDiv');
//alert(d0.length);
//alert(pp0.length);
var report ="";
for (var i = 0; i < d0.length; i++) {
    report += d0[i].textContent+"%0D%0A";//gets the date for day1
    for (var j = 0; j < pp0.length; j++) {
        report += pp0[j].textContent+"%0D%0A";//gets the d0 formDiv children. I want to out put this with line breaks
    }     
}

OutPut:

What I want to do is:

Sun Apr 19 2015 
Project One
Enter Description Here.
Total Time: 00:00:00 

Answer 1

%0D%0A are url encoded versions of line breaks, and as such you should be seeing the literal %0D and %0A characters instead of "nothing" that your example shows.

For plaintext views, such as in a text file, "View Source" in a browser, or within a <pre> tag, you'll want to use \\r\\n instead:

report += d0[i].textContent + "\r\n";

However, if you want the newlines to display in HTML (outside of the <pre> tag), you'll want to use <br /> :

report += d0[i].textContent + "<br />";

Answer 2

if you gone to print to console:

console.log("1111\ncdcd")

and if its HTML:

$(element).text("AAAA <br/> BBBB <br/> CCCCC")
