JavaScript - Textbox Border Color Problem
Hi there, I would like to highlight the textbox's border to red when it is not filled, but to no avail. The codes are as shown below, and I hope you guys can help me solve it.
Javascript Code: function check(checkForm) { var fields = new Array("First Name","Last Name","Email Address", "Domain Name"); var index = new Array(),k=0; for(var i=0;i<fields.length;i++) { var isFilled = false; var c = document.getElementsByName(fields[i]); for(var j = 0; j < c.length; j++) if(!c[j].value == "") isFilled = true; if(!isFilled) { index[k++] = fields[i]; } } if(k.length!=0) { joinComma = index.join(', '); alert('The field(s) corresponding to '+ joinComma + ' is/are not selected.'); return false; } } HTML Code: <label> *First Name:</label> <input type="text" id="Text26" name="First Name"/> <br /> <br /> <label> *Last Name:</label> <input type="text" id="Text27" name="Last Name" /><br /> <br /> <label> *Email Address:</label> <input type="text" id="Text28" name="Email Address" /> @ <select id="Select5" name="Domain Name"> <option></option> <option>hotmail.com</option> <option>yahoo.com</option> </select> input id="Submit5" type="submit" value="Submit" onclick="return send_check(this.checkForm)"/> Similar TutorialsHello, I need your help. Using Javascript, on mouseover/hover, I would like to change the boder color of my textbox from rgb(142, 142, 142) to black: rgb(0, 0, 0,) then when I move the mouse pointer off the textbox, I would like it to change from black back to rgb(142, 142, 142).

I have form and i want to input data using barcode and it will display on textbox and after input on the first textbox the focus will go to next textbox untill it will go on the last textbox and on the last textbox it will automatically save the data's on the database. How is it possible? here is my sample code: Code: <?php error_reporting(0); date_default_timezone_set("Asia/Singapore"); //set the time zone $con = mysql_connect('localhost', 'root',''); if (!$con) { echo 'failed'; die(); } mysql_select_db("mes", $con); ?> <html> <head> <script type="text/javascript"> function ini() { // Retrieve the code var code =document.getElementById ("code_read_box1").value; var code =document.getElementById ("code_read_box2").value; var code =document.getElementById ("code_read_box3").value; var code =document.getElementById ("code_read_box4").value; var code =document.getElementById ("code_read_box5").value; var code =document.getElementById ("code_read_box6").value; // Return false to prevent the form to submit return false; } </script> </head> <body onLoad="document.barcode.code_read_box1.focus()"> <form name=barcode onsubmit = "return ini()"> <input type="text" id="code_read_box1" value="" /><br/> <input type="text" id="code_read_box2" value="" /><br/> <input type="text" id="code_read_box3" value="" /><br/> <input type="text" id="code_read_box4" value="" /><br/> <input type="text" id="code_read_box5" value="" /><br/> <input type="text" id="code_read_box6" value="" /><br/> </form> </body> </html> Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section. What am I doing wrong? Thank you for your time and help. Code: <script type="text/javascript"><!-- function updatesum() { document.frmtotal.total.value = parseInt(document.form1.basic.value) + parseInt(document.form2.supporter.value)} //--></script> <tr> <td width="111"><form id="form1" name="form1" method="post" action=""> <label for="basic">$</label> <input name="basic" type="text" id="basic" size="7" maxlength="7" onchange="updatesum(this.form)" /> </form></td> </tr> <tr> <td><form id="form2" name="supporter" method="post" action=""> <label for="supporter">$</label> <input name="supporter" type="text" id="supporter" size="7" maxlength="7" onchange="updatesum(this.form)" /> </form> Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? Code: <form name="signup" action="javascript:void(0);" method="post"> <table> <tr> <td>Date Of Birth:</td> <td> <input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" /> <input name="DOBday" type="text" value="DD" size="2" style="color: #555555;" onFocus="clearDOBday()" /> <input name="DOByear" type="text" value="YYYY" size="4" style="color: #555555;" onFocus="clearDOByear()" /></td> </tr> <tr> <td></td> <td><button name="Submit" type="submit" style="font-size: 1em;">Sign Up</button></td> </tr> </table> </form> <script type="text/javascript" language="javascript"> <!-- document.signup.DOBmonth.value="MM"; document.signup.DOBday.value="DD"; document.signup.DOByear.value="YYYY"; function clearDOBmonth() { document.signup.DOBmonth.value="";} function clearDOBday() { document.signup.DOBday.value="";} function clearDOByear() { document.signup.DOByear.value="";} function restoreDOBmonth() { if ('document.signup.DOBmonth.value = ""') { document.signup.DOBmonth.value = "MM"; // alert(document.signup.DOBmonth.value); } } //--> </script> Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code: var a = document.form.textbox.value; a = blue; does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks! Hi, I'm faced with a problem trying to set background color under IE7. I have the following Javascript: Code: function showLayer793BKColor(id) { var txtObj = document.all(id); if (txtObj.style.display == 'none') { txtObj.style.display = '' txtObj.style.backgroundColor = 'grey'; } } function hideLayer793BKColor(id) { var txtObj = document.all(id); if ( txtObj.style.backgroundColor == 'grey' ) txtObj.style.display = 'none'; } These functions are used to show or hide div blocks. These blocks are, for example, specified in the following way: Code: <div id="l_gct5tekst" style="display:none"> <b>GCT 5. Eerste verkenning problematiek</b> and, for example, Code: <div id="l_Keuze" style="display:none"> <br/> <b>GCT 5</b> <br/> </div> The whole configuration works smoothly when using IE8. However, when using IE7 I get an error msg like "Invalid value for property". When I use the Color propert iso the BackgroundColor property I get no error anymore but of course I don't have a background color anymore then. In what way can I specify the use of a background color under IE7 ? Or is just not possible in one way or the other. Furthermore, what more differences between JS under IE7 and IE8 do I have to take into account ? Do I also have to rewrite my div block in some way (using some attribs ?) to cope with IE7 ? Thanks in advance, Diederick van Elst Hi! New to JS... have been trying to rework this to call additional, independent sets of colors to cycle through (so it would loop thru a set of grays, a set of primary colors, etc). I would use perhaps a different function name in the HTML to call different sets of colors. If this is more complex than I think it is, I think 3 sets would be plenty. Would be hugely grateful for any help, thanks so much in advance.

Hey guys, I recently found a small code in internet which use option value in select tag to insert value in text box, so text box has the exact same value as selected option: Code: <form name="theform" onsubmit="CheckForm()"> <select name="myOptions" onchange="document.theform.showValue.value=this.value"> <option name="(some dynamic text)" id="(some dynamic text)" value="I am the first option">I am the first option</option> <option name="(some dynamic text)" id="(some dynamic text)" value="I am the second option">I am the second option</option> <option name="(some dynamic text)" id="(some dynamic text)" value="I am the third option">I am the third option</option> <option name="(some dynamic text)" id=""(some dynamic text)" value="I am the third option">I am the fourth third option</option> </select> <input type="text" name="showValue"><br> </form> Now what I want is simple and a little different from this one, I want the text box value to be as exact as selected option name or id (doesn't matter which one) which means if an option selected, text box value has to follow that option name or id. Thanks folks. |
