我想简单地.show()基于Web表单单选按钮(用户)选择的div.
为简洁起见,我们可以在下方(但请注意,我正在寻找一些可扩展的建议,因为我的网页表格将分别有7个问题和5个答案.我有5个结果div)
注意：//所以,基本上会有7个问题和5个答案.所以我需要一个带有5个可能答案组合的数组,通过用户单选按钮选择,理想情况下使用输入’value’字段;所以我可以简单地改变组合值与div结果屏幕相等的值. div结果屏幕只是div中5个独特的内容集,就是这样.
加价：
<div class="page1">
<form class="sampler">
<input type="radio" name="sex" value="male" checked>Male
<br>
<input type="radio" name="sex" value="female">Female
</form>
</div>
<div class="page2">
<form class="sampler">
<input type="radio" name="food" value="tacos" checked>Tacos
<br>
<input type="radio" name="food" value="spicynuts">Rotten Spicy Peanuts
</form>
</div>
<div id="resultsONE"><!-- one results div is display none by default sample but there would be much more content here -->
<p>Congratulations, you are NOT the father</p>
</div>
我知道下面是可怕的语法;但这是我考虑从JS方面开始考虑的逻辑.注意我将有5个独特的结果#divs.
function resultsdivONE () {
if ($input value == "male" & "tacos") {
$('#resultsONE').show();
} else if () {
// do
} else {
// do
}
}
正如我上面提到的;我正在寻找一种方法,我只需使用SELECTED输入值=“”;所以它们可以很容易地改变.
例.
if ("male" & "tacos" & "nextanswer" & "nextanswerafter") { // etc up to 7
$('#resultsONE').show();
} // first results div
可能对PHP选项开放.
谢谢参观！
解决方法:
显示结果div基于Web表单单选按钮选择
要做什么？
基本上,所搜索的是一个包含单选按钮和结果的简单表单,它应该与无线电选择的组合相匹配.根据问题,问题应该易于维护和改变,而不总是触及脚本或其初始逻辑.
这投票支持外包问题和逻辑 – 将其与DOM分开.
怎么实现呢？
在问题标签中提到并且进一步可见的是PHP和ajax.鉴于可能希望完全外包问题并通过ajax从PHP中获取它们.外包的另一票.
需要做些什么呢？
>是否需要任何框架和/或库？不一定,但它可能是有用的
>检索JSON
>创建DOM元素
>我们是否一直需要DOM中的所有问题和答案？并不是的
For brevity lets take below (but note I’m looking for somewhat scaleable advice as my web form will have 7 questions and 5 answers each. And I have 5 results divs)
>我建议动态创建DOM,因为 – 直到现在 – 没有理由一直保留它,这使得HTML文件本身看起来更加纤薄和整洁.
>此外,可以分离布局,结构,逻辑和数据,最终允许您通过更改一个文件来更改答案和问题.
>使用这样的方法,您可以使用不同的问题创建更多表单,但代码相同.
>如果您尚未使用任何库/框架,请不要仅为此脚本添加一个.
结论
为了使其易于维护,问题和答案将外包到json文件(此处为JSON.js).鉴于此,还可以通过PHP或任何web服务检索它和/或将它们存储在数据库中.此外,提供了创建具有不同问题的多个表单的可能性,这些问题都使用相同的代码.

编辑：
在写我的建议时,我遇到了一个小问题.鉴于你的解释“有七个问题和五个结果”.某些结果是分享结果还是没有？
变化
为了解决共享结果问题,我认为有两种方式我认为输入和维护最简单.
我们列出结果两次
这个解决方案听起来可能很愚蠢.但它易于维护和管理.明显的缺点是缺乏数据完整性.
{"requirement": ["male", "spicynuts", "team a"], "message": "one has chosen male, spicynuts and team a"},
{"requirement": ["female", "spicynuts", "team a"], "message": "one has chosen male, spicynuts and team a"}
我们在需求上嵌套列表
另一种方法是嵌套需求(数组/对象中的数组),以便可以简单地列出具有相同消息的更多需求.这里的垮台是,即使一个人从不需要它,也必须以这种方式构建它.
{
"requirement": [
["male", "tacos", "team rocket"],
["male", "spicynuts", "team rocket"],
["female", "tacos", "team rocket"],
["female", "spicynuts", "team rocket"]
],
"message": "team rocket rocks my socks!"
}
结论
最后,我决定让用户决定并支持这两种方法以及初始和解决方案二的组合.人们可以像以前一样构建它,可以用相同的消息重复答案,也可以嵌套要求.
我们需要改变什么？
//Going to show the result according to the asked questions
showResult: function(){
var tValues = []; //Storing our answers
for(var i=0, j=this.mJSON.questions.length; i<j; i++)
if (this.mJSON.questions[i].value) tValues.push(this.mJSON.questions[i].value)
//Going to store the result text
var tResult = 'No match for ' + tValues.join(',');
//Looping through all requirements to get a match
var tBreak = false; //We use this to double break both loops
for(var i=0, j=this.mJSON.answers.length; i<j && !tBreak; i++){
//The requirements which need to match the values
var tR = this.mJSON.answers[i].requirement;
//We put simple arrays in a nested array to keep the same logic/process
var tRR = (typeof tR[0] === 'string') ? [tR] : tR;
for(var k=0, l=tRR.length; k<l && !tBreak; k++){
//For this we filter all the elements which do not match the requirements
var tF = tValues.filter(function(e){return tRR[k].indexOf(e) === -1})
//If that list is empty, all elements matched and we can stop
if (!tF || tF.length === 0){
tResult = this.mJSON.answers[i].message;
tBreak = true;
}
}
//If that list is empty, all elements matched and we can stop
if (!tF || tF.length === 0){
tResult = this.mJSON.answers[i].message;
break;
}
}
//Now we are going to dislpay the result
var tH = document.createElement('h1');
tH.innerHTML = tResult;
this.mContainer.appendChild(tH)
},
