error: [onChange script error: RangeError: Maximum call stack size exceeded

[jieLian123]

I write a string convert code.

but when I call it through form, I got an error below.

onChange script error: RangeError: Maximum call stack size exceeded function () { [native code] }

can anyone help me.

Hi @jieLian123 

Your code might be creating an endless loop due to which the call stack (part of the memory) exceeds the limit. Please have a look on the below posts to troubleshoot. Also, debug your code to see where the loop is being created and fix it.

Thanks.

I have move the toHalfWidth function to a script include using GlideAjax and called it in my onChange script.

it seems working well when I input something the first time.

but when I was tring to change it again to trigger the script.

I cannnot change it, I kept getting the converted value the first time script include returns to me.

Hi @jieLian123 

Can you please share your script include code as well ? Also, I can see 2 On-Change Client Scripts. Any particular reason for that ?

Thanks & Regards

yeah,please refer to the script include code below.

and I have removed one onChange script.

I successfully turn a full width string 'アアアアアアア１２３４５'

to a half width  'ｱｱｱｱｱｱｱ12345' .

but when I was trying to change 'ｱｱｱｱｱｱｱ12345' to something else, I just cannnot change it 

in the form.

var stringConvert = Class.create();

stringConvert.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

    stringConvertToHalfWidthHiragana: function(str) {

        var str1 = this.getParameter('sys_parm1'); // 引数"sys_parm1"を取得

        // 全角ひらがなを半角ひらがなに変換

str1 = str1.replace(/[Ａ-Ｚａ-ｚ０-９]/g, function(s) {

            return String.fromCharCode(s.charCodeAt(0) - 0xFEE0);

        });

        str1 = str1.replace(/[\u3041-\u3096]/g, function(s) {

            return String.fromCharCode(s.charCodeAt(0) + 0x60);

        });
