1st time when I click the <a> link it shows my table, but not hiding back when i click it next time. what i m doing wrong.

回答1:

You are trying to alter the behaviour of onclick inside the same function call. Try it like this:

Anchor tag

<a id="loginLink" onclick="toggleTable();" href="#">Login</a>

JavaScript

function toggleTable() {
    var lTable = document.getElementById("loginTable");
    lTable.style.display = (lTable.style.display == "table") ? "none" : "table";
}

Simple using jquery

<script>
$(document).ready(function() {
    $('#loginLink').click(function() {
    $('#loginTable').toggle('slow');
    });
})
</script>

You need to modify your function as:

function toggleTable()
{
   if (document.getElementById("loginTable").style.display == "table" ) {
       document.getElementById("loginTable").style.display="none";

   } else {
      document.getElementById("loginTable").style.display="table";

}

currently it is checking based on the boolean parameter, you don't have to pass the parameter with your function.

You need to modify your anchor tag as:

<a id="loginLink" onclick="toggleTable();" href="#">Login</a>

回答4:

inside your function toggleTable when you do this line

document.getElementById("loginLink").onclick = toggleTable(....

you are actually calling the function again. so toggleTable gets called again, and again and again, you're falling in an infinite recursive call.

make it simple.

function toggleTable()
{
     var elem=document.getElementById("loginTable");
     var hide = elem.style.display =="none";
     if (hide) {
         elem.style.display="table";
    } 
    else {
       elem.style.display="none";
    }
}

Your anchor tag should be:

  <a id="loginLink" onclick="showHideTable();" href="#">Login</a>

And You javascript function :

function showHideTable()
{
   if (document.getElementById("loginTable").style.display == "none" ) {
       document.getElementById("loginTable").style.display="";

   } else {
      document.getElementById("loginTable").style.display="none";

}

You are always passing in true to the toggleMethod, so it will always "show" the table. I would create a global variable that you can flip inside the toggle method instead.

Alternatively you can check the visibility state of the table instead of an explicit variable

回答7:

Try

<script>
  function toggleTable()
    {

    var status = document.getElementById("loginTable").style.display;

    if (status == 'block') {
      document.getElementById("loginTable").style.display="none";
    } else {
      document.getElementById("loginTable").style.display="block";
    }
  }
</script>

visibility property makes the element visible or invisible.

function showTable(){
    document.getElementById('table').style.visibility = "visible";
}
function hideTable(){
    document.getElementById('table').style.visibility = "hidden";
}
