Print Icon WILL Trigger User Event!

Never thought clicking Print icon on a record to get the pdf WILL fire record’s user event. This is very new to me

function _beforeSubmit(context) {
        if (context.type !== 'print') return;
        var rec = context.newRecord;
        var amountTotal = rec.getValue({ fieldId: 'total' });
        var amountChinese = getAmountChinese(amountTotal);
        log.debug('order amount: ' + amountTotal, 'amount Chinese: ' + amountChinese);
        var form = context.form;
        var field = form.addField({
            id: 'custpage_total_amount_text_p', type: serverWidget.FieldType.TEXT, label: 'amount in cn'
        });
        field.defaultValue = amountChinese;
        rec.setValue({ fieldId: 'custbody_total_amount_text', value: amountChinese });
    }

In this example, when print the record where the user event script like above is deployed to will fire the function getAmountChinese and the field custbody_total_amount_text will become available for the Advanced PDF Template, as snippet shown below.

<tr height="30px">
	<td colspan="2">运费（RMB）</td>
	<td colspan="3">${record.custbody_po_shipping_fee}</td>
	<td colspan="3">合计金额（大写）</td>
	<td colspan="4">${record.custpage_total_amount_text_p}</td>
	</tr>

This is fairly new to me because I never thought UE would be fired when print, but it does make some sense since printing is a typical user event as it retrieves data on a record basis.

没想到单据上的打印按钮能触发UE脚本，很神奇。懒得写中文部分了就这样吧
