Text To Html In Sharepoint Using Javascript

I have a summary single-line text column in SharePoint 2007 that is a truncation of a multi-line text column. Going through the complicated process to get there, it turns into tex

Solution 1:

How about using Christophe's techniques to output HTML using a calculated column.

Specifically he has written javascript that will turn the encoded HTML (which you've now got) into HTML.

Add the following into a Content Editor Web Part (CEWP) on the same page.

<scripttype="text/javascript">/*
Text to HTML Lite - version 2.1.1
Questions and comments: Christophe@PathToSharePoint.com
*/functionTextToHTML(NodeSet, HTMLregexp) {
   varCellContent = "";
   var i=0;
   while (i < NodeSet.length)
   {
      try 
      {
         CellContent = NodeSet[i].innerText || NodeSet[i].textContent;
         if (HTMLregexp.test(CellContent)) 
            { NodeSet[i].innerHTML = CellContent; }
      } 
      catch(err)
      {}

      i=i+1;
   }
}

// Calendar viewsvar regexpA = newRegExp("\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*");
TextToHTML(document.getElementsByTagName("a"),regexpA);

// List viewsvar regexpTD = newRegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
TextToHTML(document.getElementsByTagName("TD"),regexpTD);

</script>

Solution 2:

I have modified the TextToHTML code from below link, source is PathToSharePoint.com and I have added an event listener which works on SharePoint 2016 successfully in IE compatiblity mode which runs as IE10 and Chrome latest version: Text to Html conversion in Sharepoint 2010

<scripttype="text/javascript">/*
  Text to HTML Lite - version 2.1.1

  */document.addEventListener("DOMContentLoaded", function() {
    functionTextToHTML(NodeSet, HTMLregexp) {
      varCellContent = "";
      var i = 0;
      while (i < NodeSet.length) {
        try {
          CellContent = NodeSet[i].innerText || NodeSet[i].textContent;
          if (HTMLregexp.test(CellContent)) {NodeSet[i].innerHTML = CellContent;}
        }
        catch (err) {}
        i = i + 1;
      }
    }

    // Calendar viewsvar regexpA = newRegExp("\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*");
    TextToHTML(document.getElementsByTagName("a"), regexpA);

    // List viewsvar regexpTD = newRegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
    TextToHTML(document.getElementsByTagName("TD"), regexpTD);

    // This function is call continuesly every 100ms until the length of the main field changes// after which the convert text to HTML is executed.var postElemLength = 0;
    functionPostConvertToHtml() {
      if (postElemLength == document.getElementsByTagName("TD").length) {
        setTimeout(PostConvertToHtml, 100);
      }
      else {
        var regexpTD = newRegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
        TextToHTML(document.getElementsByTagName("TD"), regexpTD);
      }
    }

    // Grouped list viewsExpGroupRenderData = (function(old) {
      returnfunction(htmlToRender, groupName, isLoaded) {

        var result = old(htmlToRender, groupName, isLoaded);
        var regexpTD = newRegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
        TextToHTML(document.getElementsByTagName("TD"), regexpTD);
      };
    })(ExpGroupRenderData);

    // Preview pane viewsif (typeof (showpreview1) == "function") {
      showpreview1 = (function(old) {
        returnfunction(o) {
          var result = old(o);
          var regexpTD = newRegExp("^\\s*<([a-zA-Z]*)(.|\\s)*/\\1?>\\s*$");
          TextToHTML(document.getElementsByTagName("TD"), regexpTD);
        };
      })(showpreview1);
    }
  });
