我有个问题。我正在尝试根据单选按钮选择对“activationframe”和“equipmentframe”div 进行显示/隐藏。我让它工作得很好,但后来客户决定在等式中添加样式单选按钮。这打破了我的显示/隐藏切换。如何将其合并到样式化的单选按钮 JS 中?
这是样式化的单选按钮脚本:
var checkboxHeight = "25";
var radioHeight = "25";
var selectWidth = "190";
document.write('<style type="text/css">input.styled { display: none; } select.styled { position: relative; width: ' + selectWidth + 'px; opacity: 0; filter: alpha(opacity=0); z-index: 5; } .disabled { opacity: 0.5; filter: alpha(opacity=50); }</style>');
var Custom = {
init: function() {
var inputs = document.getElementsByTagName("input"), span = Array(), textnode, option, active;
for(a = 0; a < inputs.length; a++) {
if((inputs[a].type == "radio") && inputs[a].className == "styled") {
span[a] = document.createElement("span");
span[a].className = inputs[a].type;
if(inputs[a].checked == true) {
position = "0 -" + (radioHeight*2) + "px";
span[a].style.backgroundPosition = position;
}
inputs[a].parentNode.insertBefore(span[a], inputs[a]);
inputs[a].onchange = Custom.clear;
if(!inputs[a].getAttribute("disabled")) {
span[a].onmousedown = Custom.pushed;
span[a].onmouseup = Custom.check;
} else {
span[a].className = span[a].className += " disabled";
}
}
}
inputs = document.getElementsByTagName("select");
for(a = 0; a < inputs.length; a++) {
if(inputs[a].className == "styled") {
option = inputs[a].getElementsByTagName("option");
active = option[0].childNodes[0].nodeValue;
textnode = document.createTextNode(active);
for(b = 0; b < option.length; b++) {
if(option[b].selected == true) {
textnode = document.createTextNode(option[b].childNodes[0].nodeValue);
}
}
span[a] = document.createElement("span");
span[a].className = "select";
span[a].id = "select" + inputs[a].name;
span[a].appendChild(textnode);
inputs[a].parentNode.insertBefore(span[a], inputs[a]);
if(!inputs[a].getAttribute("disabled")) {
inputs[a].onchange = Custom.choose;
} else {
inputs[a].previousSibling.className = inputs[a].previousSibling.className += " disabled";
}
}
}
document.onmouseup = Custom.clear;
},
pushed: function() {
element = this.nextSibling;
if(element.checked == true && element.type == "radio") {
this.style.backgroundPosition = "0 -" + radioHeight*3 + "px";
} else {
this.style.backgroundPosition = "0 -" + radioHeight + "px";
}
},
check: function() {
element = this.nextSibling;
this.style.backgroundPosition = "0 -" + radioHeight*2 + "px";
group = this.nextSibling.name;
inputs = document.getElementsByTagName("input");
for(a = 0; a < inputs.length; a++) {
if(inputs[a].name == group && inputs[a] != this.nextSibling) {
inputs[a].previousSibling.style.backgroundPosition = "0 0";
}
element.checked = true;
}
},
clear: function() {
inputs = document.getElementsByTagName("input");
for(var b = 0; b < inputs.length; b++) {
if(inputs[b].type == "radio" && inputs[b].checked == true && inputs[b].className == "styled") {
inputs[b].previousSibling.style.backgroundPosition = "0 -" + radioHeight*2 + "px";
} else if(inputs[b].type == "radio" && inputs[b].className == "styled") {
inputs[b].previousSibling.style.backgroundPosition = "0 0";
}
}
},
choose: function() {
option = this.getElementsByTagName("option");
for(d = 0; d < option.length; d++) {
if(option[d].selected == true) {
document.getElementById("select" + this.name).childNodes[0].nodeValue = option[d].childNodes[0].nodeValue;
}
}
}
}
window.onload = Custom.init;
这是我显示/隐藏的旧脚本:
function showhideInstall(installtype) {
if (installtype == "equipmentswap") {
document.getElementById("activationframe").style.display = 'none';
document.getElementById("equipmentframe").style.display = 'block';
} else {
document.getElementById("activationframe").style.display = 'block';
document.getElementById("equipmentframe").style.display = 'none';
}
}
最后,我的 HTML:
<div id="activationtoggle">
<form class="radiobuttons">
<input type="radio" name="installtype" value="activation" class="styled" onclick="showhideInstall(this.value);" checked> New Activation
<input type="radio" name="installtype" value="equipmentswap" class="styled" onclick="showhideInstall(this.value);" > Equipment Swap
</form>
</div>
<div id="activationframe">
<div id="activationchecklist">
code here
</div>
<div id="equipmentframe">
<div id="equipmentswap">
<h2>Equipment Swap</h2>

</div>
任何帮助将不胜感激。我在 JS(充其量)中处于中等水平,这已被证明是一个巨大的时间槽。
