尝试将两个值从 php 发送到 JS

Question

Im retrieving a value from my db, displays on screen as a 0.

echo "<article>" . $gr_display['status'] . "</article>"; 

Then when im clicking on this DIV i want to send both status and id to my JS function, edit. The ID of this object is 79

echo "<div onclick='edit( " . $gr_display['status'] . "." . $gr_display['id'] . " )' </div>";

Then the start of my script

function edit(status, id) { 
console.log(status, id ); some code later }

But im ending up with the result that id and status is combined into one sett of value, leaving the other one "undefined"

From console log: 0.79 undefined

Answer 1

Please make a clarity between PHP and JavaScript. You need to use the right separator and separate.

echo "<div onclick='edit( " . $gr_display['status'] . ", " . $gr_display['id'] . " )'> </div>";
//-----------------------------------------------------^

Replace . with , . Also please use > for the opening <div> . You forgot to close your opening div .

Answer 2

you have at typo change the . into , between the 2 variables

    echo "<div onclick='edit( " . $gr_display['status'] . "," . $gr_display['id'] . " )'> </div>";
//---------------------------------------------------------^

or better use data-attributes

echo "<div class='edit-element' data-status='" . $gr_display['status'] . "' data-id='" . $gr_display['id'] . "'></div>";

    $('.edit-element').click(function(){
          console.log($(this).attr('data-status'),$(this).attr('data-id'));
    });

Answer 3

用这个替换 div：-

echo "<div onclick='edit( " . $gr_display['status'] . "," . $gr_display['id'] . " )' </div>";

Answer 4

The problem is causes by this line:

echo "<div onclick='edit( " . $gr_display['status'] . "." . $gr_display['id'] . " )' </div>";

Notice that between the two arguments you put a '.' instead of a ',' (a comma). That way, the second argument in your JS function does not have a value

Answer 5

Your code has two issues

1. You haven't close opening div tag
2. Use , to separate two parameters

echo "<div onclick='edit( " . $gr_display['status'] . ", " . $gr_display['id'] . ")'>ddd </div>";


<script type="text/javascript">
    function edit(status, id) { 
        alert(status);
        alert(id);
    }
</script>
