Question

I have a problem with changing objects display property with Javascript.

I fill a table from data in a mysql database using php, and for each row it makes a DIV with display:none property as I want, and I have a simple JavaScript function to show/hide the div.
Here is css for div :

display:none; /*initially menu item is hidden*/
position: absolute; /*absolute positioning to float*/
background-color:#fff;
width:230px;
min-height:120px;
right:60px;
border:5px solid #ccc;
text-align:right;
direction:rtl;
padding:10px;
border-radius: 10px 10px 10px 10px; 
-moz-border-radius: 10px 10px 10px 10px; 
-webkit-border-radius: 10px 10px 10px 10px; 

and this is the javascript :

function showfield (a) {
    document.getElementById(a).style.display = "block";  
}
function hidefield (a) {
    document.getElementById(a).style.display = "none";  
}

The function works and divs show at the place they must, but the problem is :

when I call the JavaScript function to show, it shows the div but the page scrolls to its top and for seeing the opened div I should scroll down, as my page is a report page it may be a long long page and this is not a good happening at all!

I can’t understand why its happens and is there a way to prevent this auto scrolling?

Answer 1

please try below code its working for me.

<script>
 function showfield(a)
  {
    document.getElementById(a).style.display = "block";  
  }
   function hidefield(a)
  {
      alert(a);
    document.getElementById(a).style.display = "none";  
  }
</script>
<a href="javascript:void(0)" onclick="showfield('myid')">show</a>
<a href="javascript:void(0)" onclick="hidefield('myid');">hide</a>

<div id="myid">test content goes here</div>
