[英]Hide four input boxes based on drop down selection
我想隐藏四个输入框。 当我使用if
而else
只隐藏两个盒子。 我的代码是常规JavaScript,但我会接受jQuery解决方案。
window.onload = function() {
var select = document.getElementById("billing_type");
select.onchange = function() {
if (select.value == "2") {
document.getElementById("secondpuppytable").style.display = "inline";
}
else if (select.value == "3") {
document.getElementById("thirdtable").style.display = "inline";
}
else{
document.getElementById("firsttable").style.display = "none";
}
}
}
如果我理解正确,你就会遇到“状态”问题。 当所选选项发生更改时,表的状态(要显示的表)应该更改。
您可以像这样实现它:(HTML)
<select id="billing_type">
<option value="0">1</option>
<option value="1">2</option>
<option value="2">3</option>
</select>
<div id="firsttable">firsttable</div>
<div id="secondpuppytable" style="display:none">secondpuppytable</div>
<div id="thirdtable" style="display:none">thirdtable</div>
使用Javascript:
window.onload = function() {
function tableSwitcher(tables) {
this.tables = tables;
this.activeTable = tables[0];
}
tableSwitcher.prototype.setActiveTable = function (i) {
this.activeTable.style.display = "none";
this.activeTable = this.tables[i];
this.activeTable.style.display = "inline";
}
var select = document.getElementById("billing_type");
var tables = [
document.getElementById("firsttable"),
document.getElementById("secondpuppytable"),
document.getElementById("thirdtable")
];
var switcher = new tableSwitcher(tables);
select.onchange = function() {
switcher.setActiveTable(select.value);
};
}
希望这可以帮助!
