JavaScript - Fetching String Into Js

Hello everyone,

I've got a problem while trying to fetch some informations from multiple forms in the same page.
What I'm trying to do with this code is fetching informations from the multiple forms on my page and checking if the information is the information I need.
If so, I take this information and add it into a javascript generated form that I submit once every form in the page have been taken care of.

It's the only way I found to 'submit' multiple forms at the same time.

Everything was fine until I decided to give the user the option to add more forms on the page by clicking on a button (the form is then generated by javascript and appended on the page).

There seems to be a problem when checking these particular forms, the script doesn't seem to recognize the value of the radio button (wich is add_question_faq) and never ever enters in this case. Code:

case "add_question_faq":
        alert ("pourquoi, ho, pourquoi")
        if (mesForms[cpt].question.value=="" || mesForms[cpt].answer.value==""){
        chaineModif+="StopSendRightNow"
        }
        break;

Except when the commentarised
Code:

//for (h=0;h<mesForms[cpt].elements.length;h++){
//alert (mesForms[cpt].elements[h].name)
//}

ain't commentarised.

Any Idea why a simple alert changes the behavior of the function?


Here's the said function:

Code:

 function select_forms_faq(){

        var chaineModif=""
        var mesFormsModif=new Array();
        var mesForms=document.getElementsByTagName("form");
        
        for (cpt=0;cpt<mesForms.length;cpt++){

        //for (h=0;h<mesForms[cpt].elements.length;h++){
        //alert (mesForms[cpt].elements[h].name)
        //}

        if (mesForms[cpt].action.length!=0 && mesForms[cpt].action.length!=undefined){

        for (k=0;k<mesForms[cpt].action.length;k++){

        if (mesForms[cpt].action[k].checked==true){
        
        switch (mesForms[cpt].action[k].value){
        
        case "delete":
        chaineModif+="<input type=\'text\' name=\'delete_"+mesForms[cpt].id_question.value+"\' value=\'"+mesForms[cpt].id_question.value+"\' />";
        break;
        case "save_changes_question":
        chaineModif+="<input type=\'text\' name=\'update_question_faq_"+mesForms[cpt].id_question.value+"\' value=\'id"+mesForms[cpt].id_question.value+"question"+mesForms[cpt].question.value+"answer"+mesForms[cpt].answer.value+"\' />"
        break;
        case "save_changes_cat":
        chaineModif+="<input type=\'text\' name=\'update_cat_faq_\' value=\'id"+mesForms[cpt].id_cat.value+"category"+mesForms[cpt].cat.value+"\' />"
        break;
        case "add_question_faq":
        alert ("pourquoi, ho, pourquoi")
        if (mesForms[cpt].question.value=="" || mesForms[cpt].answer.value==""){
        chaineModif+="StopSendRightNow"
        }
        break;
        }
        }
        }
        }
        }
        if (chaineModif!="" && chaineModif.indexOf("StopSendRightNow")==-1){
        var formFinal=document.createElement("form")
        with(formFinal){
        method="POST"
        action=""
        name="formFinal"
        id="formFinal"
        style.display="none"
        }
        chaineModif+="<input type=\'hidden\' name=\'submit_changes_faq\' value=\'submit_changes_faq\' />"
        document.getElementById("wpbody-content").appendChild(formFinal)
        document.getElementById("formFinal").innerHTML=chaineModif
        formFinal.submit();
        return false
        }
        else{
        return false
        }
    }

Hello all. I am working on a userscript for a site that grabs some weather information for each NFL game. I am trying to loop GM_xmlhttpRequest(s), which has worked okay, but doesn't seem to mix well with arrays. By that I mean I am attempting to push values onto an array, but it doesn't seem to work. So basically at the bottom of the code below, I get values for wind, but not for each windArray[i]. My hunch is that has something to do with the asynchronous behavior of GM_xmlhttpRequest, but I am wondering if there is anyway around that (coding wise). I greatly appreciate any input you can provide.

Code:

//Strips all html elements from a string
String.prototype.stripTags = function() {
  return this.replace(/<\/?[^>]+>|&[^;]+;|^\s+|\s+$/gi,'');
}
			
var weatherURL = new Array();
weatherURL[0] = 'http://www.nflweather.com/game/2011/week-1/bills-at-chiefs';
weatherURL[1] = 'http://www.nflweather.com/game/2011/week-1/bengals-at-browns';
weatherURL[2] = 'http://www.nflweather.com/game/2011/week-1/steelers-at-ravens';

var windArray = new Array();

function getDOC(url, callback) {
    GM_xmlhttpRequest({
        method: 'GET',
        url: url,
        onload: function (responseDetails) {
          var dt = document.implementation.createDocumentType("html", 
              "-//W3C//DTD HTML 4.01 Transitional//EN", "http://www.w3.org/TR/html4/loose.dtd"),
            doc = document.implementation.createDocument('', '', dt),
            html = doc.createElement('html');

          html.innerHTML = responseDetails.responseText;
          doc.appendChild(html);
          callback(doc);
        }
    });
}

for (var i=0; i<weatherURL.length; i++) {

getDOC(weatherURL[i], function(doc) {   	
	
	var pageTds = doc.getElementsByClassName('no-line');
	var wind = pageTds[9].innerHTML.stripTags();
	//alert(wind);
	windArray.push(wind);
	//alert(windArray[i]);
	});
}

Hey all.

I'm looking for a way to have a single, random line fetched from multiple text files, and then have that combination output somewhere, whether just to some field or another text file.

For example:

Text file A - I like I hate I love I despise I cherish
Text file B - apples bananas oranges grapes grapefruit pineapple cherries
Text file C - some of the time. most of the time. a lot of the time. pretty much never.
So it would go in, get a line from each, and display something like:

I love - grapefruit - most of the time.
I cherish - pineapple - some of the time.

etc. etc.

I know it's a weird-sounding example, but you get the point. The line choices don't have to be separated by hyphens, but they preferably would be separated by something, like a comma, semi-colon, slash, whatever.

I know this is pretty much a web coding forum, so that would be fine if I had to host it on my server or open it with a browser. But it would be optimal if this could be made into a standalone executable.

I'm basically looking for something like Random Line Picker, just with the added functionality I mentioned.

I'd be willing to make a little donation to someone if coding this would be a little difficult.

Thanks!

function Button1_onclick() {
var v = 'parser2.php?data='+document.getElementById('message').value;
ShowWebSite(v);
}

This is my code. I want to retain the \n in end of each line so that PHP can handle the input more well. But document.getElementById removes the \n. Is their any way to prevent this?
