【cognos客制化】 定制搜索框 step by step

分享至上，xiaof为你讲述cognos组件的定制开发

在“【cognos客制化】定制cognos组件”这篇概述性文章之后，有朋友想了解具体过程，我在下文就详细讲讲开发过程：）具体过程难以言尽，希望对大家有所帮助~

定制搜索框 step by step

1. 通过js从text prompt 中获取val_#值，然后将其放在value prompt中显示

2. 与此同时，将val_#值添加到隐藏的text prompt组中，起到缓存的作用

3. 之后将val_#中的值作为filter筛选条件添加到query中去

   Step one and step two, fetch data and insert it to self-made cache

   function addOption(Name) {

        //get the cognos contorl item

        var tName = "_t" + Name;

        var vName = "_v" + Name;

        var fW = (typeof getFormWarpRequest == "function" ? getFormWarpRequest() :  document.forms["formWarpRequest"]); 

        if ( !fW || fW == undefined) { fW = ( formWarpRequest_THIS_ ? formWarpRequest_THIS_ : formWarpRequest_NS_ );} 

        var valueLength = 3;

        var textComponent = eval("fW._textEditBox" + tName);

        var valueComponent = eval("fW._oLstChoices" + vName);

        valueComponent.options.add(new Option(textComponent.value, textComponent.value));

        var valueNum = valueComponent.options.length;

        for (var fi = valueNum; fi < valueLength+1; fi++)

        {

              var subTextComponent = eval("fW._textEditBox" + tName + fi);

              subTextComponent.value = textComponent.value;

        } 

   }

   Step three, add query to filter data

   (upper([REPORT_MANAGER_NOTES_ID]) contains upper(?P_Manager1?)) 

or (upper([REPORT_MANAGER_NOTES_ID]) contains upper(?P_Manager2?)) 

or (upper([REPORT_MANAGER_NOTES_ID]) contains upper(?P_Manager3?))
