How To： 用 SharePoint 计算列做出你自己的KPI列表
关于这个计算列的应用我是利用公司的网络在国外的blog看到的，国内需要FQ才能看到，真不知道这有什么可封的，唉……分享给大家吧：） 要做成这个KPI效果需要一个辅助的Column。我先简单叙述一下场景。一个SharePoint Task列表，我们要根据Today和Due Date两个时间之间的关系来显示不同的KPI。规则是这样的：
1 Today < Due Date = Green Status Icon
2 Today >= Due Date = Red Status Icon
3 Due Date not filled out = N/A
1 Create Today Column. Column type is "Date and Time".
2 Create the first Calculated Column and named "DateDiff".
3 Input formula: =IF(="";"2";IF(Today<;"1";"0")).
"0" : Today >= Due Date
"1" : Today < Due Date
"2" : Due Date = ""
4 Select "Single line of text" of "The data type returned from this formula is".
5 Upload icons to the picture library which we want to use.
6 Back to the list. Create "Status Icon" column. Column Type is "Calculated". "The data type returned from this formula" is "Single line of text". Input the formula:
=IF(="1","<DIV></DIV>",IF(="0","<DIV></DIV>",IF(="2","N/A")))
7 We will get this result of this list.
8 Now we have to change HTML to a picture.
Add a Content Editor Web Part to the page and add it below the Tasks Web Part. And input its content.
<script type="text/javascript">
//
// Text to HTML
//
var theTDS = document.getElementsByTagName("TD");
var i=0;
var TDContent = "";
while(i < theTDS.length){
try {
TDContent = theTDS.innerText||theTDS.textContent;
if ((TDContent.indexOf("<DIV")==0) && (TDContent.indexOf("</DIV>")>=0)){
theTDS.innerHTML = TDContent;
}
}
catch(err){}
i=i+1;
}
//
// ExpGroupRenderData overwrites the default SharePoint function
// This part is needed for collapsed groupings
//
function ExpGroupRenderData(htmlToRender, groupName, isLoaded){
var tbody = document.getElementById("tbod"+groupName+"_");
var wrapDiv = document.createElement("DIV");
wrapDiv.innerHTML = "<TABLE><TBODY id=\"tbod"+groupName+"_\" isLoaded=\""+isLoaded+"\">"+htmlToRender+"</TBODY></TABLE>";
var theTBODYTDs = wrapDiv.getElementsByTagName("TD");
var j=0;
var TDContent = "";
while(j < theTBODYTDs.length){
try{
TDContent = theTBODYTDs.innerText||theTBODYTDs.textContent;
if((TDContent.indexOf("<DIV")==0) && (TDContent.indexOf("</DIV>")>=0)){
theTBODYTDs.innerHTML = TDContent;
}
}
catch(err){}
j=j+1;
}
tbody.parentNode.replaceChild(wrapDiv.firstChild.firstChild, tbody);
}
</script>
9 We will see the result like this.
10 Delete the Today column. We get the correct result.
