如何从页面加载时默认出现的所选文本中删除文本选择？

Question

When we refresh or reload the page, you can see a selected text in middle of circle when you click on below image portion:

1. Discuss Goals & Concern
2. Cash Flow Analysis
3. Tax Analysis...

And so on.

Example: http://ivyfa.advisorproducts.com/financial-planning-process

The selected text is only coming on the first click - when you click again on those image portions you will not see selected text. So I want to remove the selection from the text on the first attempt too.

It's difficult for me to explain this issue. Below is the JS code I am using - I think the issue is in the ChangeText() functionality.

/*----------Text change on click - Our Process page---------------*/
var prev;
var IdAry = ['slide1', 'slide2', 'slide3', 'slide5', 'slide8', 'slide9', 'slide12', 'slide13', 'slide14', 'slide15', 'slide16'];
window.onload = function() {
  for (var zxc0 = 0; zxc0 < IdAry.length; zxc0++) {
    var el = document.getElementById(IdAry[zxc0]);
    if (el) {
      setUpHandler(el);
      el.onmouseover = function() {
        $(this).addClass("hover");
      }
      el.onmouseout = function() {
        $(this).removeClass("hover");
      }
    }
  }
}
function setUpHandler(el) {
  /*---------This is used to add selected class on clicked id only and remove class selected from rest---------*/
  $("#" + IdAry.join(",#")).click(function() {
    $(this).addClass("selected");
    $("#graphics .selected").not(this).removeClass("selected");
  })
  /*---------This will add show hide class to thier spans and vise versa-------*/
  $("#" + IdAry.join(",#")).click(
    function() {
      changeText(this, "hide", "show");
    },
    function() {
      changeText(this, "show", "hide");
    })
}
function changeText(obj, cl1, cl2) {
  obj.getElementsByTagName('SPAN')[0].className = "hide";
  obj.getElementsByTagName('SPAN')[1].className = "show";
  if (prev && obj !== prev) {
    prev.getElementsByTagName('SPAN')[0].className = "show";
    prev.getElementsByTagName('SPAN')[1].className = "hide";
  }
  prev = obj
}

I only want to remove the selected text from the text in the middle when you click on different-2 image tag.

You should clear text selection once you display your control; you can do this by calling this function (should be fully cross-browser):

function clearSelection() {
    if (window.getSelection) window.getSelection().removeAllRanges();
    else if (document.selection) document.selection.empty();
}
