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([Due Date]="";"2";IF(Today<[Due Date];"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([DateDiff]="1","<DIV><img src=http://nnitsharepoint/SiteImage/ewr209m.gif></DIV>",IF([DateDiff]="0","<DIV><img src=http://nnitsharepoint/SiteImage/ewr210m.gif></DIV>",IF([DateDiff]="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[i].innerText||theTDS[i].textContent;

    

if ((TDContent.indexOf("<DIV")==0) && (TDContent.indexOf("</DIV>")>=0)){

    theTDS[i].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[j].innerText||theTBODYTDs[j].textContent;

    

if((TDContent.indexOf("<DIV")==0) && (TDContent.indexOf("</DIV>")>=0)){

    theTBODYTDs[j].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.
