将值从PHP传递给JavaScript [重复]

• How do I pass variables and data from PHP to JavaScript? 19 answers

I have PHP code as in the following.

<?php
    echo "<SCRIPT LANGUAGE='javascript'>add dd_Employee('".$id1."','".$fname1."',".$sal1.");</SCRIPT>";
    echo "<SCRIPT LANGUAGE='javascript'>add dd_Employee('".$id2."','".$fname2."',".$sal2.");</SCRIPT>";
    ....

?>
...

And my JavaScript code contains

var details=new Array();

function addEmployee(id,fname,salary){
    var temp=new Array(id,fname,salary);
    details[details.length]=temp;
    alert(temp);
}

function displayEmployee(){
    for (var i=0;i<details.length;i++)
        var temp_details=details[i];

    //Display the id,name,sal
    var id=temp_details[0];
    var name=temp_details[1];
    var sal=temp_details[2];

    alert(id);
    alert(name);
    alert(sal);
}

Now the problem is whatever assigned by the PHP will visble only in AddEmployee. Which means it is working fine. But inside displayEmployee the value assigned by PHP will not work. Is there any flaw in my logic?

Just populate your global data structure directly rather than passing it through a JavaScript function. You are likely running into a variable scope problem since you are allocating memory in addEmployee.

Example:

<?php
print "details[details.length] = new Array('$id1', '$name1', '$salary1');
";
?>
