我一直在盯着下面的代码几个小时,我不知道从哪里开始如何解决这个问题。事先,我认为这更像是一个javascript问题,然后是一个Microsoft Web API问题,因为我实际上是在复制和粘贴他们的代码。
我正在尝试使用Microsoft Excel的Web API在我的网页上嵌入Excel工作表(工作正常)。更具体地说,我试图在单元格上突出显示时,它会在警告javascript框中显示所选单元格的值。
以下是他们的工作示例,其中包含我正在尝试执行的代码http://www.excelmashup.com/APIBrowser#example105
只需将标签从“输出”更改为右下方的“HTML”,即可查看与以下相同的代码:
<html>
<head>
<script type="text/javascript" src="http://r.office.microsoft.com/r/rlidExcelWLJS?v=1&kip=1"></script>
<script type="text/javascript">
// run the Excel load handler on page load
if (window.attachEvent) {
window.attachEvent("onload", loadEwaOnPageLoad);
} else {
window.addEventListener("DOMContentLoaded", loadEwaOnPageLoad, false);
}
function loadEwaOnPageLoad() {
var fileToken = "SDBBABB911BCD68292!110/-4923638281765748078/t=0&s=0&v=!ALTlXd5D3qSGJKU";
var props = {
uiOptions: {
showGridlines: false,
selectedCell: "'Sheet1'!C9",
showRowColumnHeaders: false,
showParametersTaskPane: false
},
interactivityOptions: {
allowTypingAndFormulaEntry: false,
allowParameterModification: false,
allowSorting: false,
allowFiltering: false,
allowPivotTableInteractivity: false
}
};
Ewa.EwaControl.loadEwaAsync(fileToken, "myExcelDiv", props, onEwaLoaded);
}
function onEwaLoaded() {
document.getElementById("loadingdiv").style.display = "none";
}
// This sample gets the value in the highlighted cell.
// Try clicking on different cells then running the sample.
function execute()
{
// Get unformatted range values (getValuesAsync(1,...) where 1 = Ewa.ValuesFormat.Formatted)
ewa.getActiveWorkbook().getActiveCell().getValuesAsync(1,getRangeValues,null);
}
function getRangeValues(asyncResult)
{
// Get the value from asyncResult if the asynchronous operation was successful.
if (asyncResult.getCode() == 0)
{
// Get the value in active cell (located at row 0, column 0 of the
// range which consists of a single cell (the "active cell")).
alert("Result: " + asyncResult.getReturnValue()[0][0]);
}
else
{
alert("Operation failed with error message " + asyncResult.getDescription() + ".");
}
}
</script>
</head>
<body>
<input type="button" onclick="execute();">Execute Sample</input> <<<<<Here is the problem
<div id="myExcelDiv" style="width: 402px; height: 346px"></div>
</body>
</html>
当我将上面的内容改为onclick =“alert('hello')”时工作正常,但是当我使用execute()时它不会提醒单元格的值; 。也许有人可以将代码复制并传递到.html文件中,看看它是否只是我的问题以及Microsoft代码是否适用于他们。如果它不起作用,那也是有用的信息。
答案 0 :(得分:0)
关键是变量&#34; ewa&#34;。通常当页面加载时,在loadEwaOnPageLoad()
内有这一行:Ewa.EwaControl.loadEwaAsync(fileToken, "myExcelDiv", props, onEwaLoaded);
所以我们需要在onEwaLoaded函数中获取一个Ewa对象。我在这个地方看到了它(ewa在其他地方宣称):
function onEwaLoaded(asyncResult) {
/*
* Add code here to interact with the embedded Excel web app.
* Find out more at http://msdn.microsoft.com/en-US/library/hh315812.aspx.
*/
if (asyncResult.getSucceeded()) {
// Use the AsyncResult.getEwaControl() method to get a reference to the EwaControl object
ewa = asyncResult.getEwaControl();
//...
获得ewa对象后剩下的就没事了。没有它,那么变量ewa确实没有定义。
