    <p>I have a method in C#, which creates a JSON object of the user credentials. Below is the CS file.</p> <pre><code>public string CreateLoginjson(string strErrorType, bool blIsAuthenticated) { StringBuilder sbLoginJson = new StringBuilder(); if (blIsAuthenticated) { sbLoginJson.Append("{LoginSuccess:1"); } else { sbLoginJson.Append("{LoginSuccess:0"); } if (strErrorType != string.Empty) { if (strErrorType.TrimEnd(new char[] { ',' }) == "Token" || strErrorType.TrimEnd(new char[] { ',' }) == "BlankToken") { sbLoginJson.Append(",txtTestTokenNumber1:\"Error\""); sbLoginJson.Append(",txtTestTokenNumber2:\"Error\""); sbLoginJson.Append(",txtTestTokenNumber3:\"Error\""); sbLoginJson.Append(",txtTestTokenNumber4:\"Error\""); } if (strErrorType.TrimEnd(new char[] { ',' }) == "Password") { sbLoginJson.Append(",txtPassword:\"Error\""); } if (strErrorType.TrimEnd(new char[] { ',' }) == "UserName") { sbLoginJson.Append(",UserName:\"Error\""); } string strLoadErrorControlMessage = LoadErrorControl(strErrorType, string.Empty); if (strLoadErrorControlMessage!= string.Empty) { sbLoginJson.Append(",ErrorMessage: '" + strLoadErrorControlMessage + "'"); } } sbLoginJson.Append("}"); var LoginJson = sbLoginJson.ToString(); return LoginJson; } </code></pre> <p>Now, I need to pass the LoginJson to a JS function that checks if incorrect credentials are provided, this function finds the control &amp; adds an attribute to it JS</p> <pre><code>function GetLoginJson(strLoginJson) { if (strLoginJson != '' &amp;&amp; strLoginJson != undefined) { var objLoginJson = strLoginJson; if (objLoginJson.LoginSuccess == "1") { } else if (objLoginJson.LoginSuccess == "0") { if (objLoginJson.txtUserName != '' &amp;&amp; objLoginJson.txtUserName != undefined) { $('#txtUserName').attr("class", objLoginJson.txtUserName); } else { $('#txtUserName').attr("class", "Input"); } if (objLoginJson.txtPassword != '' &amp;&amp; objLoginJson.txtPassword != undefined) { $('#txtPassword').attr("class", objLoginJson.txtPassword); } else { $('#txtPassword').attr("class", "Input"); } if (objLoginJson.txtTestTokenNumber1 != '' &amp;&amp; objLoginJson.txtTestTokenNumber1 != undefined) { $('#txtTestTokenNumber1').attr("class", objLoginJson.txtTestTokenNumber1); } else { $('#txtTestTokenNumber1').attr("class", "Error"); } if (objLoginJson.txtTestTokenNumber2 != '' &amp;&amp; objLoginJson.txtTestTokenNumber2 != undefined) { $('#txtTestTokenNumber2').attr("class", objLoginJson.txtTestTokenNumber2); } else { $('#txtTestTokenNumber2').attr("class", "Error"); } if (objLoginJson.txtTestTokenNumber3 != '' &amp;&amp; objLoginJson.txtTestTokenNumber3 != undefined) { $('#txtTestTokenNumber3').attr("class", objLoginJson.txtTestTokenNumber3); } else { $('#txtTestTokenNumber3').attr("class", "Error"); } if (objLoginJson.txtTestTokenNumber4 != '' &amp;&amp; objLoginJson.txtTestTokenNumber4 != undefined) { $('#txtTestTokenNumber4').attr("class", objLoginJson.txtTestTokenNumber4); } else { $('#txtTestTokenNumber4').attr("class", "Error"); } $('#ErrorControl').html(''); } } } </code></pre> <p>I want to pass the JSON variable from the CS to this jQuery statement `$('#ErrorControl').html('');'</p> <p>Thanks</p>

    2. CONo, not on Page load. This function gets called once the user provides all his credentials.. & if any of the credentials are missed by the user, the ErrorControl will be displayed..

    3. COI think I understand that you want to create an HTML representation of your JSON data. Is this what you meant? $('#ErrorControl').html("Error Message: " + objLoginJson.ErrorMessage);

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
