How to setting values of InfoPath Textbox with jquery/javascript, json.

How to setting values of InfoPath Textbox with jquery/javascript, json.

Put this code in CEWP on a web part page containing an InfoPath Form Web Part.

Set delay, as InfoPath loads asynchronously, so document ready in jquery does not work.

window.onload = function()
{
    window.setTimeout(readyCall, 1000);
}

then get reference

  var textBoxEmployeeId = $("#ctl00_m_g_9053a19d_7ea2_49c3_9af1_11ab9e5bbca3_FormControl0_V1_I1_T2");
 
then call json endpoint

var url = "https://yourserver/endpoint?callback=?";
$.getJSON(url, null, function (data) {
textBoxEmployeeId.val(data["EmployeeNumber"]);
});

then set focus.  This is VERY import in InfoPath, or else it will not presist or preserve the data

textBoxEmployeeId.focus();

In InfoPath set the postback options of the field to NEVER

This way you can call json, or other web services, and write the values to InfoPath
