Example 7.14:
Built-in Functions--escape
This page uses a built-in function, escape(form.txtCharacter.value), to return the ASCII encoding value of a character in the ISO Latin-1 character set. Type one or more non-alphanumeric characters into the text box, then click on the button to see the ASCII encoding value or values:
These are the scripts we used. First, in the HEAD:
<![CDATA[
<SCRIPT LANGUAGE="JavaScript">
<!--
function ConvertASCII(form) {
form.txtASCII.value= escape(form.txtCharacter.value)
}
//-->
</SCRIPT>
]]>
Later in the Web page the function is called from this form:
<![CDATA[
<FORM>
Type any character: <INPUT TYPE="text" NAME="txtCharacter" SIZE=12><P>
<INPUT TYPE="button" VALUE="ASCII Value" onclick="ConvertASCII(this.form)"> <INPUT TYPE="text" NAME="txtASCII" SIZE=20>
</FORM>
]]>
