<body>
<script type="text/javascript">
$(document).ready(function(){
var correctday = document.getElementById('correctday').innerText;
var correctweek = document.getElementById('correctweek').innerText;
//强制转换为数值型
correctday = parseFloat(correctday);
correctweek = parseFloat(correctweek);
//alert (correctday);
//alert (correctweek);
if (correctday < correctweek) {
document.getElementById( "correctday" ).style.color = "red";
}
if(createday >= correctweek) {
document.getElementById( "correctday" ).style.color = "green";
};
</script>
<h3>汇总(括号内为一周均值)</h3>
