Question

请任何人都可以帮助我，我被单选按钮困住了。当用户单击单选按钮下的提交按钮时，应将其重定向到新窗口，例如target =“ _ blank”

请提供任何解决方案。

然后我更改window.location.href 两个窗口。打开代码无法正常工作

function getCheckedValue(radioObj) {
if(!radioObj)
    return "";
var radioLength = radioObj.length;
if(radioLength == undefined)
    if(radioObj.checked)
        return radioObj.value;
    else
        return "";
for(var i = 0; i < radioLength; i++) {
    if(radioObj[i].checked) {
        return radioObj[i].value;
    }
}
return "";
}

// set the radio button with the given value as being checked
// do nothing if there are no radio buttons
// if the given value does not exist, all the radio buttons
// are reset to unchecked
function setCheckedValue(radioObj, newValue) {
if(!radioObj)
    return;
var radioLength = radioObj.length;
if(radioLength == undefined) {
    radioObj.checked = (radioObj.value == newValue.toString());
    return;
}
for(var i = 0; i < radioLength; i++) {
    radioObj[i].checked = false;
    if(radioObj[i].value == newValue.toString()) {
        radioObj[i].checked = true;
    }
}
}

input[type=radio] {
    -webkit-appearance: radio;
    -O-appearance: radio;
    -moz-appearance: radio;
    opacity:1;
}

#header .bottom-header.blog h1 {

input[type=radio]:hover + label {

input[type=email]:hover {

Answer 1

您应该使用window.open(url, '_blank')，它将在新标签页中打开网址。我再次说，在新选项卡中打开肯定会受到弹出窗口阻止程序的打击。我建议您使用带有target="_blank"的锚标签代替按钮（并在单选按钮的a中更改href标签的onchange）不会被弹出窗口阻止拦截器

function getCheckedValue(radioObj) {
if(!radioObj)
    return "";
var radioLength = radioObj.length;
if(radioLength == undefined)
    if(radioObj.checked)
        return radioObj.value;
    else
        return "";
for(var i = 0; i < radioLength; i++) {
    if(radioObj[i].checked) {
        return radioObj[i].value;
    }
}
return "";
}

// set the radio button with the given value as being checked
// do nothing if there are no radio buttons
// if the given value does not exist, all the radio buttons
// are reset to unchecked
function setCheckedValue(radioObj, newValue) {
if(!radioObj)
    return;
var radioLength = radioObj.length;
if(radioLength == undefined) {
    radioObj.checked = (radioObj.value == newValue.toString());
    return;
}
for(var i = 0; i < radioLength; i++) {
    radioObj[i].checked = false;
    if(radioObj[i].value == newValue.toString()) {
        radioObj[i].checked = true;
    }
}
}

input[type=radio] {
    -webkit-appearance: radio;
    -O-appearance: radio;
    -moz-appearance: radio;
    opacity:1;
}

#header .bottom-header.blog h1 {
    font-size: 64px;
	color: red
}

input[type=radio]:hover + label {
border: solid 1px white; padding: 5px; border-radius: 1px;
border-color : red;
color : red;
opacity:1;

}  

input[type=radio]:checked + label {
border: solid 2px white; padding: 5px; border-radius: 1px;
border-color : red;
color : red;
opacity:1;
}

input[type=text] {
font-weight:bold;
}
input[type=text]:hover {
}
input[type=email]:hover {
}

<form name="radioExampleForm" method="get" action="" onsubmit="return false;">
<p>&nbsp;<label for="number0"><input type="radio" value="http://www.google.com" name="number"     id="number0"> Zero</label></br>

&nbsp;<label for="number2"><input type="radio" value="http://www.gamestop.com" name="number" id="number2"> Two</label></br>

<input type="button" onclick="window.open(getCheckedValue(document.forms['radioExampleForm'].elements['number']), '_blank');" value="Buy Now">

</form>

使用以下脚本执行任务

    $("input[type='button']").click(function(){
        var numbers = document.getElementsByName('number');
        var num_value;
        for(var i = 0; i < numbers.length; i++){
            if(numbers[i].checked){
                num_value = numbers[i].value;
                // alert(num_value);
                window.open(num_value, '_blank');
            }
        }
    });

在单选按钮中打开新的选项卡窗口？
