Javascript – Get Value for ANY control

Here is a simple but hopefully useful javascript function …..

The syntax differs slightly on code needed to grab the text value of a field depending on its type. Here is a little function I have often used to make your code easier to read and removes the need to worry about the type of fields.

I tend to have a number of functions of this type included in a javascript file called something like “new_common.js”, which I add to all of the forms I want to use javascript on.

Then to find the text value of a field I will simply include code such as this ….

accountName = GetText("name");
primaryContact = GetText("primarycontactid");

// *** Gets the text for any control ***
function GetText(fieldName) {
    var control = Xrm.Page.ui.controls.get(fieldName);
    var value;
    if (control != undefined && control != null) {
        var type = Xrm.Page.data.entity.attributes.get(fieldName).getAttributeType();
        switch (type) {
            case "optionset":
                value = control.getAttribute();
                if (value != null) {
                    return value.getText();
                } else {
                    return ""
                };
                break;
            case "lookup":
                value = control.getAttribute().getValue();
                if (value != null) {
                    return value[0].name;
                } else {
                    return ""
                };
                break;
            default:
                value = control.getAttribute().getValue();
                if (value != null) {
                    return value;
                } else {
                    return ""
                };
        }
    }
    else {
        // **** Invalid control Name..
        alert("Nothing found with name - " + fieldName);
    }
};
