javascript - 如何仅在一个窗口/选项卡中打开 HTML

Question

我想做的事 -

1) On Click of a button I will open a new window(popup).

2) When I click on same button, If the window(popup)is already open I will not open it again instead bring the previously opened window(popup) on top of all windows.

3) If popup is not open I will use window.open() to open a popup.

到目前为止我做了什么 -

1) On Click of a button I will open a new window(popup).

2) Problem : How do I not allow opening of new window on click of button if window is already open?

给你:

Javascript函数:

<script language="javascript" type="text/javascript">
function popitup(url) {
    newwindow=window.open(url,'name','height=200,width=150');
    if (window.focus) {newwindow.focus()}
    return false;
}
</script>

HTML 标签:

<a href="popupex.html" onclick="return popitup('popupex.html')">Link to popup</a>
