JavaScript字符串串联错误

Question

<a href="#">{{ meeting.date }}</a>


$('.meet a').click(function() {
    var txt = $(this).text();
    var url = "http://localhost:8000/meeting_display/" + txt;
    $("a").attr("href", url);
});

In the above function, I am trying to go to a url on click on the anchor element. But everytime, the value of url is " http://localhost:8000/meeting_display/%20 *value of txt *

Thus I am not able to create a hyperlink to the intended page. Please help me.

As @alex said, use trim to remove blank space :

<a href="#">{{ meeting.date }}</a>


$('.meet a').click(function() {
    var txt = $(this).text();
    txtTrim = $.trim(txt);
    var url = "http://localhost:8000/meeting_display/" + txtTrim;
    $("a").attr("href", url);
});
