techniques for transferring data when launching a new window using javascript

   <input type="text" id="first_one" value="<?php echo $from_date ; ?>" />

Anchor Tag

In this section, there is an anchor tag. When clicked, a function is triggered.

 <script type="text/javascript">
function newwin() { 
    var a = document.getElementById("first_one").value; 

    myWindow = window.open('try1.php?leadid=a', 'myWin', 'width=400,height=650');
}
</script>

The purpose of this function is to open a new window and pass the value from the textbox when the anchor tag is clicked. However, currently it is not working as expected. Can anyone assist me with this issue?

Answer №1

Consider giving this a try:

myNewWindow=window.open('attempt2.php?visitorid=' + encodeURIComponent(data),'myNewWin','width=400,height=650')

You may have been consistently passing the character 'data' instead of providing the true value of data.

Answer №2

Give this a shot:

window.myWindow=window.open('try1.php?leadid=' +
                    encodeURIComponent(param),'myWin','width=400,height=650')

The problem you're facing is that 'param' should be treated as a variable and not a value, causing the literal string "param" to be passed instead of its actual value.

Using encodeURIComponent helps ensure that the value is safe for inclusion in URLs.

Answer №3

Combining strings:

access('testing1.php?identifier=' + x +'
