Question

我想构建自定义Google搜索。

我尝试了this one

我的代码

<div>
<form id="cse-search-box" action="http://google.com/cse" target='if2'>
  <input type="hidden" name="cx" value="009827885688477640989:igzwimalyta" />
  <input type="hidden" name="ie" value="UTF-8" />
  <input type="text" name="q" size="31" />
  <input type="button" name="sa" value="Search" onclick="doit()" />
</form>
</div>
<div>
<iframe name="if2" id="if2" width="100%" height="600px" marginheight="0" frameborder="0">
</iframe>
</div>

它的工作。然后，当更多数据来自Google时，我尝试删除高度滚动条。但它说错误就像 不安全的JavaScript尝试使用网址google.com/...从URL为192.168.9.185/KLMS/CustomGoogleSearch.aspx的框架访问框架。域，协议和端口必须匹配

有没有任何方法可以在不使用Iframe（如ajax调用）的情况下从Google获取数据 [编辑]

我试过

请帮忙。

你可以尝试使用ajax调用，当它返回时设置iframe的大小。

// get AJAX http request
var xmlhttp = getXMLHttpRequest();
function getXMLHttpRequest() {
var xhr;
if (window.XMLHttpRequest) {
    //code for IE7+, Firefox, Chrome, Opera, Safari
    xhr = new XMLHttpRequest();
}
else {
    //code for IE6, IE5
    xhr = ActiveXObject("Microsoft.XMLHTTP");
}
return xhr;
}

发送AJAX请求并听取回复：

window.doit = function() {
    xmlhttp.onreadystatechange = function () {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            //This is used when AJAX returns
            //xmlhttp.responseText contains all markup sent back from google

            //Determine size of iframe
            $("#if2").attr('width', '100%');
            $("#if2").attr('height', textHeight(xmlhttp.responseText) + "px");

            //Used to set the contents of the iframe
            //May have to be adapted to get the response to a specific place in the iframe tag hierarchy
            $("#if2").attr('src', "data:text/html;charset=UTF-8," + escape(xmlhttp.responseText));
        }
    };
    xmlhttp.open("POST", "http://google.com/cse", true);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.send("cx=009827885688477640989:igzwimalyta&ie=UTF-8&q=31");
};

测量响应的高度（改编自Calculating text width）：

//Measures the size of the returned text
function textHeight(text){
  $("body").append('<span id="tempSpan" style="display:block;">' + text + '</span>');
  var height = $("#tempSpan").height();
  $("#tempSpan").remove();
  return height;
};
