Lets say there is a combobox with 3 values:a,b,c. There are also 3 text boxes. There is a database with 1 table which contains 4 columns. Now, how exactly can I update the values of the 3 inputboxes whenever I select a different value in the combobox. Lets say combobox represents the data in column 1 of the database table, textbox1 reporesents data for column 2, textbox2 for column3 and textbox3 for column4, so that the values of the text input boxes changes accordingly.
让我们说有一个组合框有3个值:a,b,c。还有3个文本框。有一个包含1个表的数据库,其中包含4列。现在,每当我在组合框中选择不同的值时,我究竟能如何更新3个输入框的值。让我们说组合框表示数据库表第1列中的数据,textbox1表示第2列的数据,第3列的textbox2和第4列的textbox3,因此文本输入框的值会相应地更改。
I am really sorry for being vague. Hope someone can still help me out. This has to be done using php html ajax and mysql.

this has to be done in javascript mainly. something like this (no valid code just mockup)
这必须主要在javascript中完成。像这样的东西(没有有效的代码只是模型)
<select onchange="changeInputBoxes(this)"...> .... </select>
<script>
function changeInputBoxes(){
document.getElementById("inputid").value = this.value;
...
}
</script>
but its really to vague.
但它真的很模糊。
