你好

我想表明这个弹出来中心点击时的“你好”

Answer 1

要在你需要使用的宽度和屏幕的高度中心打开。一个在点击打开刚才绑定它的window.onload：

 function open1() { 

      var left = (screen.width - 400)/2, 
       top = (screen.height - 200)/2, 
       settings = 'height=200,width=400,top=' + top + ',left=' + left; 

      window.open('http://www.pageresource.com/jscript/jex5.htm','popUp',settings); 
     } 

     window.onload = function(){ 
      document.getElementById("openPopup").onclick = open1; 
     } 

Answer 2

ID为“开放式”创建HTML元素和嵌入这个脚本插入到文档的头：

function open1() { 

    var w = 400, // width of your block 
     h = 200, // height of your block 
     l = (screen.width - w)/2, // block left position 
     t = (screen.height -h)/2; //block top position 

    window.open('http://www.pageresource.com/jscript/jex5.htm','','height=' + h + ',width=' + w + ',top=' + t + ',left=' + l); 
} 

window.onload = function() { 
     document.getElementByID("open").onclick = open1; 
}
