3.js 页面

function Showloadinfo() {
self.document.getElementById("loadinfo").style.display = "inline";
self.document.getElementById("main").disabled = true;

}
function Showloadinfo1() {
    self.document.getElementById("loadinfo").style.display = "inline";
    self.document.getElementById("main").disabled = true;
    document.getElementById("ddlbut").click();

}
function Showloadinfo2() {
    self.document.getElementById("loadinfo").style.display = "inline";
    self.document.getElementById("main").disabled = true;
    document.getElementById("txtbut").click();

}

function Closeloadinfo() {
self.document.getElementById("loadinfo").style.display = "none";
self.document.getElementById("main").disabled = false;
}

注：当要在下拉表控件和文本控件改变时添加进度条使用的方法
