Save text from javascript variable to .txt file

I am trying this code, but can't get it to work, it says "The name "text" does not exist in the current context"
CurBrowser.GetMainFrame().ExecuteJavaScriptAsync("for(var i = 0; i < elems1.length; i++){ var textt = elems1[i].innerText}");
string docPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt"), true))
{
outputFile.WriteLine(textt);
}
How can I make variable "textt" accessible?
Here is a full code:
private void button3_Click(object sender, EventArgs e)
{
CurBrowser.GetMainFrame().ExecuteJavaScriptAsync("var elems1 = document.getElementsByClassName('question-text')");
CurBrowser.GetMainFrame().ExecuteJavaScriptAsync("for(var i = 0; i < elems1.length; i++){var textt = elems1[i].innerText}");
string docPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt"), true))
{
outputFile.WriteLine(textt);
}
}

You might be looking for ContinueWith() which can be chained after ExecuteJavaScriptAsync().
In this example you need to use your JavaScript code as a function which returns anything (ex. textt). So I've created something like this:
var myScript = #"(function () {
var textt = "";
var elems1 = document.getElementsByClassName('question-text');
for(var i = 0; i < elems1.length; i++){
textt += elems1[i].innerText
}
return textt;
})();";
than I asynchronously evaluate it and catch the result which I am returning from that function:
var result = await CurBrowser
.GetMainFrame()
.EvaluateScriptAsync(myScript)
.ContinueWith(t => {
var result = t.Result; // your textt
string docPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt"), true)) {
outputFile.WriteLine(result);
}
});
this is just a suggestion of how it might work.

replace all values using javascript in an xml payload

i have a xml string that i will replace all values of specific tags using javascript,
and this is the code :
function replaceDomainName (xmlPayload,domainId)
{
var oldDomain = '<DOMAIN_NAME>OOO';
var oldDomain2 = '<DomainName>OOO';
var newDomain = '<DOMAIN_NAME>'+domainId ;
var newDomain2 = '<DomainName>'+domainId ;
var xmlString = xmlPayload.toString();
var x = xmlString.replace(/oldDomain/g,newDomain)
x = x.replace(/oldDomain2/g,newDomain2)
console.log(x);
return x ;
}
when I try to invoke the function with the following XML it throws error

x.replace(/<DOMAIN_NAME>OOO/g,'<DomainName>'+domainId)
use this

While you can get a lot done with Regex, it can get really complicated when parsing XML.
See this example of using DOMParser and XMLSerializer:

const XML = `<TransmissionHeader xmlns:tran="http://xmlns.oracle.com/apps/otm/TransmissionService" xmlns="">

if(typeof(String.prototype.trim) === "undefined")
{
String.prototype.trim = function()

return String(this).replace(/^\s+|\s+$/g, '');
};
}
function replaceDomainName (xmlPayload, oldValue, newValue)
{
const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlPayload,"text/xml");
for(let tagName of ['DOMAIN_NAME', 'DomainName']) {
const instances = xmlDoc.getElementsByTagName(tagName);
for (let instance of instances) {
if(instance.innerHTML.trim() == oldValue )
instance.innerHTML = newValue;
}
};
const s = new XMLSerializer();
const d = document;
const result = s.serializeToString(xmlDoc);
return result;
}
const resultXML = replaceDomainName(XML, 'OOO', 'new.com');
console.log('resultXML', resultXML);
const textarea = document.createElement("textarea");
textarea.innerHTML = resultXML;
textarea.cols = 80;
textarea.rows = 24;
document.body.appendChild(textarea);

Outputting PHP string into a JS file causes syntax error

I'm trying to output a string into a JS file using PHP. Here's the PHP code
$embedded_form_js = "document.addEventListener('DOMContentLoaded', function(){
var parts = window.location.search.substr(1).split('&');
var $_GET = {};
for (var i = 0; i < parts.length; i++) {
var temp = parts[i].split('=');
$_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);
}
var ref = $_GET['ref'];
if (ref === 'undefined')
{
ref = 0;
}
}, false);";
I'm trying to write a JS file like so
$fp = fopen("FOLDER/FILE.js", 'w');
fwrite($fp, $embedded_form_js);
fclose($fp);
The problem is that when I try to write the JS file, this error happens.
syntax error, unexpected '(', expecting ']'
This is in reference to the line:
$_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);
How can I remedy this?

use Nowdocs as it is single-quoted and won't try to interpret the $_GET
$embedded_form_js = <<<'EOS'
document.addEventListener('DOMContentLoaded', function(){
var parts = window.location.search.substr(1).split('&');
var $_GET = {};
for (var i = 0; i < parts.length; i++) {
var temp = parts[i].split('=');
$_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);
}
var ref = $_GET['ref'];
if (ref === 'undefined')
{
ref = 0;
}
}, false);
EOS;

javascript, exception for string/object manipulation

So, I have to functions to turn a string to an object and an object to a string, however I need to account for an except and I am not sure how. Let me show you what I have
parseObjectToUrl: function (obj){
var myStr = "";
var first_iteration = true;
for (var p in obj) {
if(first_iteration){
myStr += p + "=";
first_iteration = false;
}else{
myStr += "&" + p + "=";
}
tObj = obj[p];
var first_inner = true;
for(t in tObj){
if(first_inner){
myStr += t;
first_inner = false;
}else{
myStr += "," + t;
}
yObj = tObj[t];
for( y in yObj){
myStr += "/" + yObj[y];
}
}
}
return myStr;
},
parseObjectFromUrl : function(url){
var builtObj = {};
//remove first slash
url = url.slice(0, 0) + url.slice(1);
var ch = url.split('&');
var tempParent = {};
for (var p in ch) {
var tempSub = {};
var arr = ch[p].split('=');
var keyParent = arr[0];
var splitInside = arr[1].split(",");
for (var i in splitInside) {
var sub = splitInside[i].split('/');
var subKey = sub[0];
tempSub[subKey] = sub.slice(1);
}
tempParent[keyParent] = tempSub;
}
return tempParent
}
So these the string looks like
/module1=mod1/2/3/4,mod2/2/3/4&module2=mod2/3/4/5
and the object looks like
myObj =
{
module1 : { mod1 : [2,3,4] , mod2 [2,3,4]} ,
module2 : { mod2 : [3,4,5]}
}
So these functions work fine for me however I (unfortunately) need to be able to handle the case when the user adds an "/" into the options like -
myObj =
{
module1 : { mod1 : [2/,3/,4/] , mod2 [2,3,4]} ,
module2 : { mod2 : [3,4,5]}
}
I'm sure it's going to throw a wrench in my function because i'm splitting by the "/", so I'm not sure how to get around this. Would i escape the slash? How would that fit into the functions if so? Looking for any advice on this issue. Thanks!
Edit:
I was able to encode the escaped url like :
obj.replace(/([/-])/g, "%2F");
to an escaped url, hoever I am having trouble doing the reverse of this. here is my attempt.
obj.replace(/(%2F)/g, "/");

in my opinion it would be better to use url arrays, but keep in mind the characters for your url could be limited:
maximum length of HTTP GET request?
having said that one could do something like this:
module1[]=1&module1[]=2&module2[]=4&module2[]=3
this is equal to the following pseudo code:
$_GET["module1"] = array(1,2);
$_GET["module2"] = array(4,3);
and use encodeURIComponent & decodeURIComponent for your values

javascript parser for a string which contains .ini data

If a string contains a .ini file data , How can I parse it in JavaScript ?
Is there any JavaScript parser which will help in this regard?
here , typically string contains the content after reading a configuration file. (reading cannot be done through javascript , but somehow I gather .ini info in a string.)

I wrote a javascript function inspirated by node-iniparser.js
function parseINIString(data){
var regex = {
section: /^\s*\[\s*([^\]]*)\s*\]\s*$/,
param: /^\s*([^=]+?)\s*=\s*(.*?)\s*$/,
comment: /^\s*;.*$/
};
var value = {};
var lines = data.split(/[\r\n]+/);
var section = null;
lines.forEach(function(line){
if(regex.comment.test(line)){
return;
}else if(regex.param.test(line)){
var match = line.match(regex.param);
if(section){
value[section][match[1]] = match[2];
}else{
value[match[1]] = match[2];
}
}else if(regex.section.test(line)){
var match = line.match(regex.section);
value[match[1]] = {};
section = match[1];
}else if(line.length == 0 && section){
section = null;
};
});
return value;
}
2017-05-10 updated: fix bug of keys contains spaces.
EDIT:
Sample of ini file read and parse

You could try the config-ini-parser, it's similar to python ConfigParser without I/O operations
It could be installed by npm or bower. Here is an example:
var ConfigIniParser = require("config-ini-parser").ConfigIniParser;
var delimiter = "\r\n"; //or "\n" for *nux
parser = new ConfigIniParser(delimiter); //If don't assign the parameter delimiter then the default value \n will be used
parser.parse(iniContent);
var value = parser.get("section", "option");
parser.stringify('\n'); //get all the ini file content as a string
For more detail you could check the project main page or from the npm package page

Here's a function who's able to parse ini data from a string to an object! (on client side)
function parseINIString(data){
var regex = {
section: /^\s*\[\s*([^\]]*)\s*\]\s*$/,
param: /^\s*([\w\.\-\_]+)\s*=\s*(.*?)\s*$/,
comment: /^\s*;.*$/
};
var value = {};
var lines = data.split(/\r\n|\r|\n/);
var section = null;
for(x=0;x<lines.length;x++)
{
if(regex.comment.test(lines[x])){
return;
}else if(regex.param.test(lines[x])){
var match = lines[x].match(regex.param);
if(section){
value[section][match[1]] = match[2];
}else{
value[match[1]] = match[2];
}
}else if(regex.section.test(lines[x])){
var match = lines[x].match(regex.section);
value[match[1]] = {};
section = match[1];
}else if(lines.length == 0 && section){//changed line to lines to fix bug.
section = null;
};
}
return value;
}

Based on the other responses i've modified it so you can have nested sections :)
function parseINI(data: string) {
let rgx = {
section: /^\s*\[\s*([^\]]*)\s*\]\s*$/,
param: /^\s*([^=]+?)\s*=\s*(.*?)\s*$/,
comment: /^\s*;.*$/
};
let result = {};
let lines = data.split(/[\r\n]+/);
let section = result;
lines.forEach(function (line) {
//comments
if (rgx.comment.test(line)) return;
//params
if (rgx.param.test(line)) {
let match = line.match(rgx.param);
section[match[1]] = match[2];
return;
}
//sections
if (rgx.section.test(line)) {
section = result
let match = line.match(rgx.section);
for (let subSection of match[1].split(".")) {
!section[subSection] && (section[subSection] = {});
section = section[subSection];
}
return;
}
});
return result;
}
