JavaScript - Need Help On Getting Values From A Textarea
I sell products on amazon. and ASINs are Amazon Identifiers for products. So If I want to check out my product pages I have to go to "www.amazon.co.uk/dp/ "I have to put an ASIN here" . If I can put everything together in the text box and hit go it should take me to the first page(first ASIN). Here is a sample ASIN B004Z2QORW
I have the code below but I somehow cant get it to work. Please help. I haven't assigned anything to the go button. I will put a list of ASINs in the text area and the iframe should concatenate the value from a row to the hardcoded URL and when I click next it should concatenate the value from the next row; when I click previous the value from the previous row. Code: <HTML>
<Head>
<H1 align="center">Detail Page Lookup using ASINs</H1>
</head>
<body>
<textarea rows="10" cols="20" value="">
ASINs here
</textarea>
<button id="go">Go</button>
<button id="prev" align="right">Previous</button>
<button id="next" align="right">Next</button>
<br/>
<iframe id="myframe" src="http://www.amazon.co.uk/dp/" height="100%" width="100%">
<p>Your browser does not support iframes.</p>
</iframe>
<script>var domain='http://www.amazon.co.uk/dp/';
$('#prev, #next').on('click', function(e) {
var Myval = $('textarea').val().split('\n'),
now = $('#myframe').attr('src').replace(domain, '');
if (Myval.indexOf(now)==-1) {
var src=domain+Myval[0];
}else{
var p = Myval.indexOf(now)!==0 ? Myval.indexOf(now)-1 : Myval.length-1,
n = Myval.indexOf(now)==(Myval.length-1) ? 0 : Myval.indexOf(now)+1,
src = e.target.id=='next' ? domain+Myval[n] : domain+Myval[p];
}
$("#myframe").attr('src', src);
console.log(src);
});
?

Hi, What's a good way/ideal data structure to achieve this? The objective of the code/function is to map user-inputted strings into a pair of specific, hard-coded strings. For example, say the user types "firefox" or "ff", or "fx". The output would be the pair ["browser", "mozilla"], for example. I'm currently using a multidimensional array, but it feels inefficient and I'm having trouble mapping an arbitrary number of inputs into 2 outputs. Code: var strings = [ ["input1", "output1a"],
["input2", "output1a"],
["input3", "output1a"],
["input1", "output1b"],
["input2", "output1b"],
["input3", "output1b"]
];
How should I map the elements ["input1", "input2", "input3"] => ["output1a", "output1b"] ? Another method I used previously was a massive switch statement. This fulfills my needs, but I'm not sure about the efficiency (though if I remember correctly, switch statements become more efficient as size grows, since it uses a hash table?). Code: switch (input) {
case "ff": case "firefox": case "fx" : case "ffox":
return ["browser", "mozilla"];
case "ie": case "internet explorer":
return ["browser", "microsoft"];
...
}
Hello there . Here is my simple code Quote: <html> <head> <script> function addText(){ document.getElementById("textarea").value+=document.getElementById("text").value+'\n'; document.getElementById("text").value=""; document.getElementById("text").onblur=document.getElementById("text").value=" Your Message..."; } </script> <style> #textarea{background-color:#F3F3F3; } </style> </head> <body> <form> <TEXTAREA id="textarea" COLS="80" ROWS="20" ></TEXTAREA><br/><br/> <input type="text" id="text" name="text" value=" Your Message..." onclick="this.value=''" size="96"> <input type="button" value="Send" name="submit" onclick="addText()"> </form> </body> </html> My problem is I dont know what to do iorder to make my send button to push the text entered in the text field from bottom to the top (not from the top to the bottom) Hi all, I'm loading external xml and displaying specific tagged elements in a textarea. It works fine in IE because I can turn the variable object into text with a simple object.text property, but in Firefox (using the serializeToString method), the object appears in my textarea tags and all. The code looks something like this (this is just a dummy script - imagine the xml is already loaded into the object xmlDoc ): Code: function writePage(){
document.write('<textarea name="inputText">'+myText+'</textarea>');
}
function xmlIsLoaded(){
if(window.ActiveXObject){ //tests for IE
myText = xmlDoc.getElementsByTagName("desiredTag")[0].text;
} else { //tests for FF
myText = (new XMLSerializer()).serializeToString(xmlDoc.getElementsByTagName("desiredTag")[0]);
}
writePage();
}
What am I missing here? I've tried toString, textContent, innerText, childNodes - just about everything I can think of to get just the text w/o the tags from the xml for the FF version. Any thoughts? ~gyz hi I am trying to create a textarea. There is a default text inside textarea. so when user clicks inside textarea then submit button appears and default text disappears and when user clicks somewhere else or outside textarea then it gets back to original state i.e, default text appears back and submit button disappears. here is what i did sofar. in this code when i click inside textarea then submit button does appear but text does not erase and when i click outside then button remains in sight.

I'm having trouble with the way my textarea is displaying text when it's submitted. It always comes out as one line of text instead of the way a user has entered it. Here's my code. Code: <textarea name="info" value="" rows="7" cols="55"> Enter Your Personal Information Here </textarea><br /><br /> That is then called to a function which displays it in a new page. Code: <script>
function buildResume()
{
resInfo = document.myResume.info.value
flyWindow = window.open()
flyWindow.document.write("Personal Information " + resInfo);
}
</script>
If any knows how I could fix this it'd really help. I've tried using the pre element and wrap property with no luck. I found a script that is perfect for my need but it is written for forms textareas and I can seem to get it to work textareas that are not wrapped in form. Code: Code: <script>function insertAtCursor(sTag,eTag)
{
var obj = document.form.message;
var strPos;
var ie_strPos;
var oSel;
obj.focus();
strPos += sTag.length + eTag.length;
ie_strPos += sTag.length + eTag.length;
if (document.selection && document.selection.createRange) { // Internet Explorer
oSel = document.selection.createRange();
if (oSel.parentElement() == obj) {
oSel.text = sTag + oSel.text + eTag;
ie_strPos += oSel.text.length;
}
oSel.moveStart ('character', ie_strPos);
oSel.moveEnd ('character', 0);
oSel.select ();
}
else if (typeof(obj) != "undefined") { // Firefox
var longueur = parseInt(obj.value.length);
var selStart = obj.selectionStart;
var selEnd = obj.selectionEnd;
obj.value = obj.value.substring(0,selStart) + sTag + obj.value.substring(selStart,selEnd) + eTag + obj.value.substring(selEnd,longueur);
strPos += txtarea.value.substring(selStart,selEnd).length;
obj.selectionStart = strPos;
obj.selectionEnd = strPos;
obj.focus ();
}
else obj.value += sTag + eTag;
obj.focus();
} </script>
<button onclick="insertAtCursor('[blah]','[/blah]')">Test</button>
<form method="post" name="form" action="">
<textarea name="message" cols="50" rows="10"></textarea>
</form>
My textarea: Code: <textarea id="new_topic_text" class="new-topic-subject-text elastic" style="overflow: hidden;"></textarea> I am fairly new at Javascript, but there is something happening I do not understand. Please someone explain it to me and help with a solution. In the function, I pull data from an URL and I have done this with several different data fields and populate the HTML input, option, and check boxes with no problem with the following method. Code: document.getElementById("othertxt").value=strValue;
document.getElementById("radsig").checked=true;
document.getElementById("eventtime").value=strValue;
But for some reason this method for textarea does not work and I know that there is a value in strValue because check it right before the line of code. Code: document.getElementById("othertxt").value=strValue;
Is textarea just treated differently? I have searched the internet and seen examples but for some reason I can not find the correct solution. Is it possible to limit a textarea input with a max amount of letters? So if the form said 1,000 character limit. Can it block it after the 1,000th one is reached? I'm adding text into a text area using document.createTextNode Code: document.getElementById('controlQueueDump').appendChild(document.createTextNode(args+';'));
But whenever the user edits the text box, it will never update anything again. I can add as much as I want, but when a user edits it (for example removes the contents), BAM, it is no longer updated. it's a textarea so it should be appending the child to the value attribute. Thanks a lot. is it possible to make a textarea resize with text? so if e.g the text overflows, the text-area is automatically resized so that there's no scrolling? It needs to resize automatically as the user is typing (more or less), he/she shouldn;t click on any buttons to resize it
Hi, Nothing will display in my textarea after pressing an input number which have to seen on the display. The code is from a simple calculator <form action="#" method="get" onsubmit="return false"> <p> <textarea disabled="disabled"></textarea> </p> <div id="calculatorButtons"> <p> <button onclick="calculatorNumber(1)">1</button> <button onclick="calculatorNumber(2)">2</button> <button onclick="calculatorNumber(3)">3</button> <button onclick="calculatorOp('+')">+</button> </p> <p> <button onclick="calculatorNumber(4)">4</button> <button onclick="calculatorNumber(5)">5</button> <button onclick="calculatorNumber(6)">6</button> <button onclick="calculatorOp('-')">-</button> </p> <p> <button onclick="calculatorNumber(7)">7</button> <button onclick="calculatorNumber(8)">8</button> <button onclick="calculatorNumber(9)">9</button> <button onclick="calculatorOp('*')">*</button> </p> <p> <button onclick="calculatorNumber(0)">0</button> <button onclick="calculatorOp(',')">,</button> <button onclick="calculatorClear()">Clear</button> <button onclick="calculatorCalculate()">Calc</button> </p> </div> </form> function calculatorNumber(i) { document.form.getElementById('textarea').innerHTML = i; } What is the right way to refer to the textarea? hi i am new to javascript. i want to make a form where a textarea, some buttons like bold,italic,link etc will be availablw. when user selecet some text from textarea and click bold button then one openig and closing tag will be added like this [sb]abc[/sb] how can i do this using javascript. any idea? pls. help I'm making this expanabel textarea which works fine, but... If I set a predefined numbers of rows, when start typing it jumps back (schrinks) into 2 rows... How do I avoid this? Code: <script>
function checkRows(textArea){
if (navigator.appName.indexOf("Microsoft Internet Explorer") == 0)
{
textArea.style.overflow = 'visible';
return;
}
while (
textArea.rows > 4 &&
textArea.scrollHeight < textArea.offsetHeight
){
textArea.rows--;
}
while (textArea.scrollHeight > textArea.offsetHeight)
{
textArea.rows++;
}
return;
}
</script>
<textarea style="overflow:hidden;" onkeyup="checkRows(this)" rows="4">Some Test Text</textarea>
Thanks in advance:-) so I am creating a silly word ;irate word interpreter page, and I need some logic behind how to add text to a textarea each time I click on a button. Each time the user clicks on the button, the value is inserted into the text area. You should be able to click on multiple buttons to add to the last text that appears. Then I have a delete translation button when I want to clear the textarea field. A good example would be if the user clicks on the button with the value "sir", than "matey" will appear in the textarea. Now, if the user clicks on the button with the value "your", then "yer" will come up after matey. It's like creating a sentence on your own, and then deleting it when your done. Code: <body> <div id="page"> <div> <img style="float:left" src="slue.gif" width="205" height="190" alt=""> <div> <h1>Pirate Translator</h1> <p>Simply click on the buttons to translate words and/or phrases from English to pirate talk</p> </div> </div><br /> <hr /> <form name="pirate"> <div> <fieldset> <legend><b>Greetings:</b></legend> <input type="button" id="greeting" value="hello" /> <input type="button" id="greeting" value="pardon me" /> <input type="button" id="greeting" value="excuse me" /> <input type="button" id="greeting" value="" /> <input type="button" id="greeting" value="" /> <input type="button" id="greeting" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>People:</b></legend> <input type="button" id="people" value="sir" /> <input type="button" id="people" value="madam" /> <input type="button" id="people" value="miss" /> <input type="button" id="people" value="stranger" /> <input type="button" id="people" value="officer" /> <input type="button" id="people" value="" /> <input type="button" id="people" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Questions:</b></legend> <input type="button" id="question" value="where is" /> <input type="button" id="question" value="can you help me" /> <input type="button" id="question" value="is that" /> <input type="button" id="question" value="how far is it to" /> <input type="button" id="question" value="" /> <input type="button" id="question" value="" /> <input type="button" id="question" value="" /> <input type="button" id="question" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Articles:</b></legend> <input type="button" id="article" value="the" /> <input type="button" id="article" value="my" /> <input type="button" id="article" value="your" /> <input type="button" id="article" value="" /> <input type="button" id="article" value="" /> <input type="button" id="article" value="" /> <input type="button" id="article" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Adjectives:</b></legend> <input type="button" id="adject" value="old" /> <input type="button" id="adject" value="attractiv" /> <input type="button" id="adject" value="happy" /> <input type="button" id="adject" value="" /> <input type="button" id="adject" value="" /> <input type="button" id="adject" value="" /> <input type="button" id="adject" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Places:</b></legend> <input type="button" id="places" value="restroom" /> <input type="button" id="places" value="restaurant" /> <input type="button" id="places" value="mall" /> <input type="button" id="places" value="hotel" /> <input type="button" id="places" value="pub" /> <input type="button" id="places" value="" /> <input type="button" id="places" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Desires:</b></legend> <input type="button" id="desire" value="I would like to" /> <input type="button" id="desire" value="I desire" /> <input type="button" id="desire" value="I wish I knew how to" /> <input type="button" id="desire" value="my mother told me to" /> <input type="button" id="desire" value="my campanion tells me to" /> <input type="button" id="desire" value="" /> <input type="button" id="desire" value="" /> </fieldset> </div> <div> <fieldset> <legend><b>Actions:</b></legend> <input type="button" id="action" value="find" /> <input type="button" id="action" value="take a nap" /> <input type="button" id="action" value="kill" /> <input type="button" id="action" value="hurt you" /> <input type="button" id="action" value="beat you up" /> <input type="button" id="action" value="go to the bathroom" /> <input type="button" id="action" value="" /> </fieldset> </div> <div> <p id="output"><textarea id="task_list" rows="5" cols="130"></textarea></p> <p id="output"><input type="button" id="" value="Delete Traslations" /></p> </div> </div> </form> <script src="js/translate.js"></script> </body> </html> Hi guys, My brain is not working.

For some reason, the stupid JS is not reading. But I think it is me that is stupid, not JS. Below is the code i'm running to get the value. Code: var message = document.getElementById('themessage').value;
alert(message);
The alert simply returns blank. There is an alert, but no value even where there is text in the text area. Can someone please shed some light on this. pretty please |
