Get certain field from returned JSON object

Question

I am editing a SharePoint List using JS Link.

Within a SharePoint-Column, I would like to display information from another SharePoint column. The source is a SharePoint Person Column (Entliehenan).

When using the following script:

(function () {


    var overrideCtx = {};
    overrideCtx.Templates = {};
    overrideCtx.Templates.Fields = { 'Status': { 'View': CustomField } }; 

    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCtx);

})();

function CustomField(ctx){
    var ret

    if (ctx.CurrentItem.Status) {
        ret = "<img style='height: 60px; width: auto;' src='~sites/100037/SiteAssets/Ampel/AmpelRot.png'></img><br><br><span style='background-color: #ffc7ce;'>lent to:&nbsp;" + ctx.CurrentItem.Entliehenbis + "&nbsp;an&nbsp"  + JSON.stringify(ctx.CurrentItem.Entliehenan) + "</span>";
    }
    else if (!ctx.CurrentItem.Status) {
        //ret = "<span style='background-color: #c6efce;'>Kann ausgeliehen werden</span>";
        ret ="<img style='height: 60px; width: auto;' src='~sites/100037/SiteAssets/Ampel/AmpelGRUEN.png'></img>"; 
    }

    else {

    }
    return ret;
}

(The responsible part in the script:)

JSON.stringify(ctx.CurrentItem.Entliehenan)

it returns

[{"id":"16","title":"Doe, John","email":"john.doe@jdoe.com","sip":"john.doe@jdeo.com","picture":""}] 

Now I would like to only display the Title of the JSON-object ("Doe, John").

How to do this?

I have tried to use:

JSON.stringify(ctx.CurrentItem.Entliehenan.title)

and

JSON.stringify(ctx.CurrentItem.Entliehenan[title])

but both return undefined.

Answer 1

Please Try using below:

ctx.CurrentItem.Entliehenan[0].title;

There is similar thread on MSDN forum: How to get people picker value using JS Link feature.

Also there is a nice article on Handling field values in JSLink:

Handling field values in JSLink.

Update(to Remove double quotes)::

You can use replace function in JavaScript as given here:

JSON.stringify(ctx.CurrentItem.Entliehenan[0].title).replace(/['"]+/g, '')
