Replacing characters with accents (french characters)

[kryles]

Hi, I am getting textbox values after the user clicks a button. The textboxes are named text00,text10,text20 etc until text200

What I want to do is take the value of the character and see if it falls between 00192 and 00253 (like Á is 00193).

This is my code:

if((String.fromCharCode(document.form1["text"+i+"0"].["charAt("+j+")"].value) > 191) && (String.fromCharCode(document.form1["text"+i+"0"].["charAt("+j+")"].value) < 253))
{
   alert("testing special chars");
  
   switch(String.fromCharCode(document.form1["text"+i+"0"].charAt([""+j+""]).value))
  {
     case 192:
     case 193:
     case 194:
     case 195:
document.form1["text"+i+"0"].charAt([""+j+""]).value = 'A';
break;
   }
}

I never get in the if statement to see my alert. Any suggestions woul dbe very much appreciated

[1] Cannot decipher meaning of form1[...]. If you mean form of name "form1" and element of name "text<i>0" for some i, it should be
[tt]document.form1.elements["text"+i+"0"][/tt]

[2] If you want to relace à by A in the value, you can simply use replace function with regexp. It should not need to loop through each char etc. Beside the last statement for replacing character is not correct.
[tt]
var oelem;
oelem=document.form1.elements["text"+i+"0"]; //for some i
oelem.value=oelem.value.replace(/\xc3/g,"A");
[/tt]
[3] For more character change with no definite code corresponding pattern, do it successively for each of them.

okay if I do it that way, will see teh change on an alert right after? I still get the accented character.

var ch = document.form1["text"+i+"0"];
ch = ch.value.replace(/\xc3/g,"A");
alert(ch);

I also did

var ch = document.form1["text"+i+"0"];
ch = ch.value.replace(/\x0193/g,"A");
alert(ch);

since 00193 is what i'm typing for Á in the test.

There isn't such a thing as \x0193 for that A-thing. Either you do \xc3 or \u00c3.

Okay so I have it working for each individual. It does not seem to like me running them through though as a group

for(i=0;i<20;i++)
{
var len = document.form1["text"+i+"0"].value.length;

if (len > 0 )
{
   var ch = document.form1["text"+i+"0"];
   ch = ch.value.replace(/\u00C0/g,"A"); // A A` 00192
   /* works perfect thx to tsuji and gil davis */
   ch = ch.value.replace(/\u00C8/g,"E"); //not working
}

it does not seem to like the way I try running the second replace. Any hints or ideas?

Thanks again,

You have to read documents of scientific & technical nature careful to every detail. The reason is you lost the object reference along the way (comparing to what I posted.)
[tt]
var ch = document.form1["text"+i+"0"];
ch[red].value[/red] = ch.value.replace(/\u00C0/g,"A"); // A A` 00192
/* works perfect thx to tsuji and gil davis */
ch[red].value[/red] = ch.value.replace(/\u00C8/g,"E"); //not working
[/tt]

Also if the replacement candidate set is becoming larger, you can retrieve the value once and do all the replacements to the string and finally write it back.
[tt]
var ch = document.form1["text"+i+"0"];
var s=ch.value;
s = s.replace(/\u00C0/g,"A"); // A A` 00192
/* works perfect thx to tsuji and gil davis */
s = s.replace(/\u00C8/g,"E"); //not working
//etc etc ...
ch.value=s;
