NetSuite/Suitescript - 为什么此验证字段脚本会进入无限循环? [英] NetSuite / Suitescript - Why does this Validate Field script enter an infinite loop?

问题描述

我的脚本进入无限循环，我不知道为什么.我在验证字段上运行这个，如果另一个供应商账单存在相同的参考号，我会阻止对该字段的更改，迫使用户将参考号"更改为唯一的.这是我的代码:

My script is entering into an infinite loop and I have no idea why. I am running this on validate field and I am preventing a change to the field if another vendor bill exists with the same reference number, forcing the user to change the "Reference Number" to be unique. Here is my code:

function validateField(type, name) {

    if (uniqueReferenceNum(type, name) === false) {

        return false;
    }

    return true;
}


function uniqueReferenceNum(type, name) {

    if (name !== 'tranid') {
        return true;
    }

    var tranID = nlapiGetFieldValue('tranid');
    var vendor = nlapiGetFieldValue('entity');
    var vendorName = nlapiGetFieldText('entity');

    var filters = new Array();
    var columns = new Array();

    filters[0] = new nlobjSearchFilter('entity', null, 'is', vendor);
    filters[1] = new nlobjSearchFilter('tranid', null, 'is', tranID);
    filters[2] = new nlobjSearchFilter('mainline', null, 'is', 'T');

    columns[0] = new nlobjSearchColumn('internalid');

    results = nlapiSearchRecord('vendorbill', null, filters, columns);

    if (!results) {

        return true;

    }


    alert("There is already a vendor bill with reference # " + tranID + " for " + vendorName + ". Please verify and change the reference number before continuing.");
    return false;
}

推荐答案

对于那些仍然面临这个问题的人，您可以将有问题的字段 - 在这种情况下，Reference Number - 设置为 'falsy' 值，例如空字符串.只有在检查字段包含真实"值后才返回 false.然后向用户显示alert 或dialog.这应该会打破验证循环.

For those still facing this issue, you can set the field in question - in this case, Reference Number - to a 'falsy' value such as an empty string. Only return false after checking that the field contains a 'truthy' value. Then display the alert or dialog to the user. This should break the validation loop.
