新浪的財金頻道一直感覺做得很好。但由于最近網(wǎng)速慢的緣故，查看股票信息時網(wǎng)頁老是打不開。這幾天一直在研究ajax，于是用jquery自己做了一個自動讀取新浪股票實時數(shù)據(jù)的頁面。

習慣用prototype的，把腳本部分的代碼替換一下即可。
復制代碼 代碼如下:
script type="text/javascript" src="prototype.js">/script>
script type="text/javascript">...
function ajaxRequest()...{
var myAjax = new Ajax.Request(
'http://hq.sinajs.cn/list=sh000001,sh601939,sh600016,sh600528,sh600667,sh601390,sh601398,sh601857,sh600028',
...{
method: 'get',
onComplete: setData
}
);
}
function setData(response) ...{
var contents = response.responseText;
var stocks = contents.split(';');
for(var i=0; istocks.length-1; i++)...{
var content = stocks[i];
var temp1 = content.split('=')[0];
var temp2 = content.split('=')[1];
var code = temp1.substr(temp1.length - 6, 6);
var temp3 = temp2.replace('"', '');
var name = temp3.split(',')[0];
var tday_f = temp3.split(',')[1];
var yest_f = temp3.split(',')[2];
var curr_f = temp3.split(',')[3];
var temp_f = curr_f - yest_f;
$('a'+i).innerHTML = code;
$('b'+i).innerHTML = name;
$('c'+i).innerHTML = curr_f;
if(curr_f > yest_f) ...{
$('c'+i).innerHTML = "font color='red'>" + curr_f + "/font>";
} else if(curr_f yest_f) ...{
$('c'+i).innerHTML = "font color='green'>" + curr_f + "/font>";
} else ...{
$('c'+i).innerHTML = curr_f;
}
$('d'+i).innerHTML = tday_f;
$('e'+i).innerHTML = yest_f;
if(temp_f > 0) ...{
$('f'+i).innerHTML = "font color='red'>" + temp_f.toFixed(2) + "/font>";
$('g'+i).innerHTML = "font color='red'>" + ((temp_f / yest_f) * 100).toFixed(2) + "/font> %";
} else if(temp_f 0) ...{
$('f'+i).innerHTML = "font color='green'>" + temp_f.toFixed(2) + "/font>";
$('g'+i).innerHTML = "font color='green'>" + ((temp_f / yest_f) * 100).toFixed(2) + "/font> %";
} else ...{

}

$('i'+i).innerHTML = temp3.split(',')[5];
}
}

window.setInterval("ajaxRequest()",3000);
}

當然頁面部分完全可以由腳本自動生成，以及頁面動態(tài)增減股票信息等功能，就等日后修改吧。
