XML页面用javascript调用Web Services的怪问题？ |
|
|
最近做一个在XML里使用javascript调用远程Web Services的程序，可是我遇到了一个怪问题，摸索了几天也没有头绪，有兴趣的朋友可以一起探讨一下.以下XML文件中调用Web Services插入数据库成功：
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="styles/common.xsl" type="text/xsl"?>
<html xmlns:u="http://housecall.trendmicro.com/xmlns/ui"
xmlns:locale="http://my.commons/XSL/PreProcess/Locale">
<head>
<u:header>
<locale:title> 安全门神－在线杀毒产品 </locale:title>
</u:header>
<script language="javascript">
function window_onload(work)
{
service.useService("http://192.1.1.203/webserver/Service1.asmx?WSDL","myselect"); 数据挖掘交友
str_province=service.myselect.callService("HelloWorld",work);
}
function open_window()
{
callId = window.open('frameset.xml','HouseCall','width=700,height=520');
}
</script>
</head>
<body onload="window_onload(1)">
<div id="service" style="BEHAVIOR:url(http://localhost/Web/webservice.htc)"> </div>
<table width="100%" style="height: 150px">

可是我在另外一个XML页面用同样的方法调用Web Services,数据没有插入数据库，非常的郁闷，代码如下：

}

</html> 没有错误提示，没有相关的信息，怎么让大家帮你判断？本来就是没有错误的，今天上午摸索了一下，发现是javascript脚本上的问题。就是发送窗体之前调用javascript函数，代码如下：
<script language="javascript"> <![CDATA[
window.handleKernelSelect = function(el) {
var show = el.value.indexOf("native") == -1;
var ctx = this.api.getContext();
// Set the current selection in the kernel
ctx.setOption("set-implementation", el.value);
// Show java alerts if necessary
if(!ctx.getBooleanOption("system-java-enabled"))
document.getElementById("no-java").style.display = show ? "block" : "none"; 数据挖掘工具
else if(!ctx.getBooleanOption("system-java-version-valid"))
document.getElementById("outdated-java").style.display = show ? "block" : "none";
}
window.initialize = function(api) {
if(this.UIInfo.getAttribute("boolean.cs.webcontent.skip.termsofuse") == "true" )
window.api.setOption("accept-terms-of-use", "true" );
// Set the initial values in the form
with(document.forms['kernelSelect']) {
elements['locale'].value = decodeUrlParameters()["locale"];
elements['accept-terms-of-use'].checked = 数据挖掘工具
api.getContext().getBooleanOption("accept-terms-of-use");
}
// Load the terms of use
this.UIInfo.termsElement = document.forms['kernelSelect'].elements['terms-of-use'];
this.UIInfo.windowRef = this;
this.UIInfo.loadTermsOfUse(function(UIInfo, content, code) {
if(code == 200)
UIInfo.termsElement.value = content;
else if(code > = 400 && code <= 505)
UIInfo.termsElement.value = "FATAL: Failed with:" + code;
else
UIInfo.windowRef.loadTermsOfUse(); // retry

onsubmit();
submit();
return false;
}
});
// Validate the input and sync the kernel options
document.forms['kernelSelect'].onsubmit = function() {

以上那个onsubmit函数的第二行(alert('确定吗？');)注释掉的话，就无法插入数据库，按照上面的代码可以插入数据库可是我并不要一个警告框(alert('确定吗？');)，从原理和html代码中的实践没有alert('确定吗？');都可以插入数据库。有没有这方面的高手指点一下。Create By Any-Extract(WL-AE) 数据挖掘论坛
