JavaScript - Selected Dropdownlist Item - Call/fetch Data
Hi All.
I have a dropdown list on a web form containing dates. My Question: How can I call data for that selected item(date) from a MySQL database and display it to the user? And more specifically, if that selected date has no data in the data base, I want to be able to display that as well. I'm looking for a Javascript solution, and if possible a php solution. Thank You! Similar TutorialsHi Peers, i have a Drop down list with 10 choices (skillset). users must choose one skillset and the corresponding level (beginer/intermediate/master). ( they have to do this 10 times for all the sillsets) what i want is : 1 - i need to show up only one record (dropdowanlist) with level then have a button to add new skill and level if required 2- then when they choose the 1st skill from the dropdown , this one will not show up on the 2nd choice dropdown. is it possible any help ? thanks guys Hello all, I am having a problem, and since I am quite new in the Javascript code I hope somebody can help me here. This is my current code: Code: <select class="Form" name="opties"> <option value="AAA">AAA</option> <option value="BBB">BBB</option> <option value="SLX" selected>Selecteer optie</option> </select> Now my intention is the following: When the option with value SLX gets selected it needs to get a special css style. It is not a problem to give the option this style in the list itself, but once selected it always changes to the original style (standard font and color) in Chrome and Mozilla. Now I searched on the net and sometimes I find things like this: Code: function displayOption(divName) { document.getElementById(divName).innerText=document.form1.select1.options[document.form1.select1.selectedIndex].value; } <select class="Form" name="opties" onChange="displayOption('div1');"> <option value="AAA">AAA</option> <option value="BBB">BBB</option> <option value="SLX" selected>Selecteer optie</option> </select> But I suppose this always changes the style of the selected item? It only needs to change when the option SLX is chosen... Anyone knows how to solve this problem? Hello, I am hoping someone can help me with following search form. As you can see I have created a form but I don't know how to fix the coding so when a user select a category it will add a different hidden filed for that option for example: When the user selects category "Men" the hidden filed Code: <INPUT TYPE="HIDDEN" NAME="REFERRER" VALUE="http://men.com/acatalog/"> will be added and when the user selects category "Kids" the hidden filed Code: <INPUT TYPE="HIDDEN" NAME="REFERRER" VALUE="http://kids.com/acatalog/"> will be added and so on... Here is my form coding I am using: Code: <form name="simplesearch" method="get" action="" onsubmit="ssite=document.getElementById('sitelist');this.action=ssite.options[ssite.selectedIndex].value;return true;"> <input type="hidden" name="page" value="search" /> <input type="hidden" name="PR" value="-1" /> <input type="hidden" name="TB" value="A" /> <input type="hidden" name="NOLOGIN" value="1" /><input align="top" class="main_search_box" name="SS" type="text" value="search for ..." onfocus="this.value='';"> Search within: <select id="sitelist"> <option value="">Select Catagory</option> <option value="http://kids.com/cgi-bin/ss000001.pl">kids</option> <option value="http://men.com/cgi-bin/ss000001.pl">men</option> <option value="http://women.com/cgi-bin/ss000001.pl">women</option> </select><input type="submit" class="button" name="ACTION" value="Go!"> </form> Also I have one more question how do I make the "Select Catagory" a Must Choose and if not chosen to give message that say"Please Select a Category" Thank you in advance for any help you can give me... I am a bigginer so please go easy on me Hiya! I'm a total JS beginner, so any help is appreciated. I've created the simple select box below that will "onchange" when an item is selected. I'm trying to apply the "selected" or "selected="selected" attribute to items that are chosen from the menu. Example: The goal is to show " <option value="/1" selected="selected"> " when page "/1" is chosen and to show <option value="/1"> when /1 is not the current page. I've follow a few simple tutorials with no luck and even tried php conditionals to trigger the "selected" attribute with no luck. Any feedback is GREATLY appreciated, thank you! Code: <form name="guideform" method="get"> <select class="wptdb_jumpbar_select" name="mymenu" onChange="window.location=document.guideform.mymenu.options[document.guideform.mymenu.selectedIndex].value"> <option value="/1">Home Page #1</option> <option value="/2">Home Page #2</option> <option value="/3">Home Page #3</option> <option value="/4">Home Page #4</option> </select> </form> Hi, I am new to javascript, Please help me with the issue below. My javascript code below should actually fetch the data from html table on button click. function displaymessage() { alert ("button pressed"); var table_cells = new Array(); var table7 = document.getElementById('Auth'); for (i=0,n=table7.rows.length; i < n ; i++) { var Rowdata = table7.rows[i]; table_cells[i] = new Array(); for(j=0,cols = Rowdata.cells.length; j < cols; j++) { table_cells[i,j] = Rowdata.cells[j].innerHTML; alert (table_cells[i,j]); } } alert (table_cells[1,1]); alert (table_cells[2,1]); alert (table_cells[3,1]); alert (table_cells[4,1]); alert (table_cells[5,1]); alert (table_cells[6,1]); alert (table_cells[7,1]); alert (table_cells[8,1]); } The problem with my code above is that the statement "alert (table_cells[i,j]);" executes properly and shows the correct value. But the other alert statements shows only the value of the last row of the table. i.e., my table has 9 rows. and all the alert statements shows 9th row's 2nd column's value outside the for loop. But inside the for loop it executes fine. I tried it in IE7. I seem to miss something. Could someone please help me out with this? Thanks in advance. I am trying for a javascript code that would ask for the excel file location when run, fetch data from two columns till eof in an excel file (MS Excel 2010), append it to an existing text file and upload the plain text file to an ftp location. The ftp username, password and location needs to be hard coded in the script. Is this possible? This is what i am trying to do. I want to have data called up when a certain number is entered. If the correct item # is entered, the information is pulled up. Is this a good application for javascript? or for something like flash and actionscript? I'm brand new to both, but i'm very willing to learn. Thanks for your help! Hi there How to send data from a text feild in GET method using an AJAX call...

Hi, I have this web browser which opens up a website that has a drop down list showing values that the user can select. And when I the firebug to inspect the elements in the page, what shows in the inspection window is this: Code: <select id="instance2" name="instance2"> <option value="0">All instances</option> <option value="1">Item0</option> <option value="2">Item1</option> <option value="3">Item2</option> . . . <option value="23">Item22</option> What I'm supposed to do is to get the values and update them automatically to the database.

I'm a beginner so I might need a lot of help on this matter. Help is kindly appreciated. Thanks. Hi everyone, now I need to add items into a dropdown list, and the items would be sorted alphabetically and it does not allow duplicate items to be added. Can anyone help take a look and see what's wrong with my code? Javascript Code: function addAnotherOption() { var newItem = document.getElementById("Text44"); if (!newItem.value == "") { var answer = confirm ("Are you sure you want to add? ") if (answer)//if answer is true { var lst = document.getElementById('comboBox'); // listbox control id // Now we need to create a new 'option' tag to add to MyListbox var newOption = document.createElement("option"); newOption.value = newItem.value; // The value that this option will have newOption.innerHTML = newItem.value; // The displayed text inside of the <option> tags for (var i = 0; i < lst.options.length; i++) { arrTexts = lst.options[i].text; if (arrTexts.toLowerCase() == newItem.toLowerCase()) { alert ("That option is already included in the list - please enter another item."); return false; } else { // Finally, add the new option to the listbox lst.appendChild(newOption); //sort items in listbox in alpha order arrTexts = new Array(); for(i=0; i<lst.length; i++) { arrTexts[i] = lst.options[i].text; } arrTexts.sort(); for(i=0; i<lst.length; i++) { lst.options[i].text = arrTexts[i]; lst.options[i].value = arrTexts[i]; } } } } } else { if(newItem.value == "") { alert("Key something to textbox please."); } else alert("Cancelled."); } } HTML Code: <input id="Text44" type="text" /> <input id="Submit22" type="submit" value="Add" onclick="addAnotherOption()" /><br /> <select name="combo" id= "comboBox" style="width: 323px"> <option value="H">Hearts</option> <option value="D">Diamonds</option> <option value="C">Clubs</option> <option value="S">Spades</option> </select> Hi Experts, i have 2 JS array and i need to have dependency between them knowing that 1st Array has parent element of the 2nd one. i.e ARRAY1 ID VAL ID2 2 Dep1 10 3 Dep2 20 4 Dep3 30 ARRAY2 ID VAL ID2 PARENT 20 team1 11 10 21 team2 12 10 22 team3 13 20 23 team4 14 30 i need to have two different DDL's where when i choose VAL = Dep1 on ARRAY1 , i should see on the 2nd DDL only elements with parent corrsponding to Dep1 ( PARENT =10). how this can be possible thanks Hi, I am hoping I just need to be pointed in the right direction with this. I have Page1. When Page1 body onloads it uses Ajax to call PartA Within PartA I have a message board so members can write messages which will be sent to my database in PartA[1] and immediately posted for view on to PartA[2]. As I want to have my request to the server updating regularly I want to have PartA[2] on a timed loop to refresh - I do not need the content of PartA[1] to refresh. So the order of events would look like this: Page1 | onload call | v PartA / \ V V PartA[1] PartA[2] (loads once) (constantly refreshes) What I am not sure about is that I have <body> and <head> attributes in Page1 only. I have already used my body onload to call PartA (and can't use it to call PartA[2] before PartA has loaded anyway). I do not want the user to have to click a button or do anything to call up PartA[2]. So my question is how would I get PartA[2] to automatically load within PartA? I hope I have made this clear, but if I haven't let me know and I will try again. I am trying to get a form value on an action page using JavaScript to alert the value. The below doesnt alert anything after I hit the submit button in the one.html page: one.html Code: <form action="two.html" method="get" id="myform"> <input type="text" name="city"> <input type="submit"> two.html Code: <html> <head> <script> alert(document.myform.city.value); </script> </head> <body> </body> </html> Please advise. |
