我有调用.cfc pag的函数。我传递方法和参数以及页面名称。这是我的代码:
function callFunction(name){
param = name;
location.href = 'myTest.cfc?method=getRecords&userName=' + param;
}
这是我在cfc页面上的功能:
<cfcomponent>
<cffunction name="getRecords" access="remote" returnformat="void">
<cfargument name="userName" type="string" required="yes">
<cfset myResult = "1">
<cftry>
<cfquery name="getResults" datasource="test">
//myQuery
</cfquery>
<cfcatch>
<cfoutput>#cfcatch#</cfoutput>
<cfset myResult="0">
</cfcatch>
</cftry>
<cfreturn myResult>
</cffunction>
</cfcomponent>
我打电话给我的函数后,我的代码没有给我返回变量。我不确定我的代码中缺少什么。如果有人可以帮助解决这个问题,请告诉我。

我不确定我是否理解这个问题,但您是否在寻找这个问题?
function callFunction(name) {
var target = 'myTest.cfc?method=getRecords&userName=' + name;
location.href = target;
return target;
}

这是从getRecords
组件中获取myTest.cfc
结果的方法。
var xhr = new XMLHttpRequest();
xhr.open('GET', 'myTest.cfc?method=getRecords&userName='+name);
xhr.send(null);
xhr.onreadystatechange = function () {
var DONE = 4; // readyState 4 means the request is done.
var OK = 200; // status 200 is a successful return.
if (xhr.readyState === DONE) {
if (xhr.status === OK)
var result = xhr.responseText; // 'This is the returned text.'
//result will = 1 or 0.
} else {
console.log('Error: ' + xhr.status); // An error occurred during the request.
}
}
};
