If I set the URL to exmaple.com?blank=true a blank page should be presented.
Using JavaScript or jQuery i want a short snippet that looks for ?blank=true in the url and if it finds it than the page to turn white or blank.
Try like this
var url_string = "https://example.com?blank=true "; //window.location.href
var url = new URL(url_string);
var blank = url.searchParams.get("blank");
if(blank){
document.getElementsByTagName("body")[0].style.display = "none";
}
<body>
<p>this will be hidden</p>
</body>
wrap your html content in a element like this
<html>
<body>
<div id="wrapper">
<!-- ********your content here******** -->
</div>
</body>
</html>
use jquery code as
$(document).ready(function() {
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('=');
if(sURLVariables[0]=="blank" && sURLVariables[1]=="true")
{$('#wrapper').css('display','none');}
else{
$('#wrapper').css('display','block');
}
});
With jQuery
var blank = /(?<=blank=)[^&?]+/g.exec('https://example.com?blank=true')[0];
if(blank === 'true'){
$('body').hide();
}else{
$('body').show();
}

I have a custom Wordpress page, with 2 text input boxes, one for "yourvarname" and the other for "key"and an iframe displaying a google document.
Both these Text boxes are populated from variables obtained from the url. This works fine.
What I would like to do:
Have the iframe display the document as named in the textbox, yourvarname.
this is what I have so far
<?php /* Template Name: CustomPageT1 */ ?>
<p><input id="yourvarname" type="text" value="" /> <input id="key" type="text" value="" />
<script type="text/javascript">// <![CDATA[
var url_string = window.location.href; //window.location.href
var url = new URL(url_string);
var c = url.searchParams.get("yourvarname");
var d = url.searchParams.get("key");
document.getElementById("yourvarname").value = c;
document.getElementById("key").value = d;
// ]]></script>
</p>
<iframe src="https://docs.google.com/document/d/e/2PACX-1vTCJM2gUN4_aesXjEB7XtKWu0dB8anwWkjgolj1zRLU2aJieScUXF6WXzMbjYXs7g/pub?embedded=true"

class="myIframe">
<p>Hi SOF</p>
</iframe>
<script type="text/javascript" language="javascript">
$('.myIframe').css('height', $(window).height()+'px');
</script>"
<script type="text/javascript" language="javascript">
global $wp_query;
if (isset($wp_query->query_vars['yourvarname']))
{
print $wp_query->query_vars['yourvarname'];
}
</script>
enter code here
Let's start with basic information. In Javascript you can get your iframes like this:
document.getElementsByTagName("iframe")
Since you have a single iframe, you can get it like this:
document.getElementsByTagName("iframe")[0]
but it would potentially save you from trouble to give an id to this tag. Let's define the src of your iframe
document.getElementsByTagName("iframe")[0].src = "somevalue";
Okay, let's apply this in your script:
var url_string = window.location.href; //window.location.href
var url = new URL(url_string);
var c = url.searchParams.get("yourvarname");
var d = url.searchParams.get("key");
document.getElementById("yourvarname").value = document.getElementsByTagName("iframe").src = c;
document.getElementById("key").value = d;
However, if you want it to change when the input changes, then you will need to define a change event for it.
so this is what i added, perhaps incorrectly, as i am now getting 404 error and nothing is displayed
<script type="text/javascript" language="javascript">
document.getElementsByTagName("iframe")[0].src = "yourvarname";
var url_string = window.location.href; //window.location.href
var url = new URL(url_string);
var c = url.searchParams.get("yourvarname");
var d = url.searchParams.get("key");
document.getElementById("yourvarname").value = document.getElementsByTagName("iframe").src = c;
document.getElementById("key").value = d;
</script>
I would like to ask for your help in having a web site that uses the following javascript:
<html>
<head>
...
</head>
<body>
...
<script>
$(document).ready(function(){
var pathArray = window.location.pathname.split( '/' );
var secondLevelLocation = pathArray[0];
var newPathname = "";
for (i = 0; i < pathArray.length; i++) {
newPathname += "";
newPathname += pathArray[i];
}
var str = "asd fgh roof_material";
var res = str.match(newPathname);
if (res) {
document.getElementById("demo").innerHTML = res;
} else {
document.getElementById("demo").innerHTML = "Basic text";
}
});
</script>
<div id="demo"></div>
</body>
</html>
Such as my website address is: https://www.mywebsite.com/roof_material
I get a string in a variable (newPathname) which contains the text after the / sign, in this example: roof_material
The problem is:
I would like to find the value of this variable in a text and if you can find it then you can post it on the website. It's works if I put a text in a variable like in the script:
var str = "asd fgh roof_material";
But I would like to find the value of this variable (newPathname) in a separate html file, if it is possible like this:
The newPathname value such as: roof_material
In the separated .html file content:
<div id="protection_material">Line-X material</div>
<div id="roof_material">Roof materials</div>
<div id="pool_material">Swimming pools</div>
In this example I would like to find the roof_material ID in the .html file and get the content of the div: "Roof materials" and I would like to show this text on the page:
<div id="demo">Roof materials</div>
If it has positive match then show the content of the div in other cases, it will print a basic text like in the example: "Basic Text"
Could anyone help to make it happen?
#Terry thanks for your answer!
I think I found a simpler solution, but it's not perfect:
<script>
$(document).ready(function(){
var pathArray = window.location.href.split('=')[1];
var secondLevelLocation = pathArray[0];
var newPathname = "";
for (i = 0; i < pathArray.length; i++) {
newPathname += "";
newPathname += pathArray[i];
}
document.getElementById("demo").innerHTML = newPathname;
});
</script>
<div id="demo">Országosan</div>
If I type it in the browser such as: https://www.mywebsite.com/index then the text that will appear in #demo div is: "Országosan"
It's good, but if I type such as: https://www.mywebsite.com/index?id=Cserkeszőlő
then the result is good but character encoding does not work properly.
The result in the #demo div: Cserkesz%C5%91l%C5%91 , but I would like to show the correct encoded text like this: Cserkeszőlő
Can you give me a solution on this?
Recently I've got into a problem. I want to add this code at my blogger templete. I've gave it replace 'display:none; css' option, replace the credit URL with my homepage features. But the if (footer === null) {window.location = 'http://google.com';} isn't working. why? Is anything wrong? I want to make client blog redirect if they remove the id='mycreditlink' attribute. I want to do this without jquery.
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function creditprotection(){
var url = ('http://grplusbd.net');
var style = ('display: inline; visibility: true;');
var footer = document.getElementById('mycreditlink');
footer.href= url;
footer.style = style;
if (footer === null) {
window.location = 'http://google.com';
}
}
window.onload = function(){creditprotection();};
</script>
</head>
<body>
Powered By <a href='http://google.com' id='mycreditlink'> My Site </a>
</body>
</html>
<head>
<script type="text/javascript">
function creditprotection(){
var url = ('http://grplusbd.net');
var style = ('display: inline; visibility: true;');
var footer = document.getElementById('mycreditlink');
if (footer == null) {
footer.href= url;
footer.style = style;
window.location = 'http://google.com';
}
}window.onload = function(){creditprotection();};
</script>
</head>
<body>
Powered By <a href='http://google.com' id='mycreditlink'> My Site</a>
</body>
You can change your function like this:
function creditprotection() {
var url = 'http://grplusbd.net';
var style = 'display: inline; visibility: true;';
var footer = document.getElementById('mycreditlink');
if (footer === null) {
window.location = 'https://google.com';
}
footer.href = url;
footer.style = style;
}
When footer is not set, it does not have the properties href or style. That's when you get an error. This can be prevented by checking when footer === null before you assign the values to the footerproperties. If the footer === null, it redirects. Else it assigns the values.
Trying to do the following:
Store params from url, i.g. mydomain.com/page.html?cid=123456
If a user clicks on a button (they have a class of .btn-cta) it will take the params ?cid=123456 and add them to the new page those buttons link to /tour.html
I'm currently doing 1/2 of that with passing the params to an iframe on the page, now I need to get the above part working:
var loc = window.location.toString(),
params = loc.split('?')[1],
iframe = document.getElementById("signupIndex"),
btn = $('.btn-cta');
iframe.src = iframe.src + '?' + params;
Here's how I'd do it using jquery:
$('.btn-cta').each(function(i, el){
let $this = $(this); // only need to create the object once
$this.attr({
href: $this.attr("href") + window.location.search
});
});
And in Vanilla ES2015
document.querySelectorAll('.btn-cta')
.forEach(el => el.attributes.href.value += window.location.search);
This takes all the elements that have class .btn-cta and appends the page query string to each of their href attributes.
So if the page url is `http://domain/page.html?cid=1234
Tour
becomes
Tour
<html>
<head>
<script src="js/jquery.js"></script>
<script>
$(document).ready(function() {
var loc = window.location.href;
var params = loc.split('?')[1];
$(".btn-cta").click(function(){
window.open("tour.html?"+params,'_self',false);
});
});
</script>
</head>
<body>
<button type="submit" class="btn-cta">Click Me</button>
</body>
</html>
I want to add script tag using javascript, but I am not able to get it work. Below is code. I want to add this code in bigcommerce cart page.
var duration = document.getElementsByName("cartdata");
var cartstr = '<!-- MyBuys Page Parameters – Place in <body> element -->';
cartstr += '<script type="text/javascript">';
cartstr += 'mybuys.setPageType("SHOPPING_CART");';
cartstr += 'mybuys.set("email","consumer#example.com"); <!--consumer email can be blank if not known-->';
cartstr += 'mybuys.set("amount","99.34");';
for (var i = 0; i < duration.length; i++) {
str = duration[i].value;
var n = str.split('|');
cartstr += 'mybuys.addCartItemQtySubtotal("'+n[0]+'","'+n[1]+'","'+n[2]+'");'+'<br>';
}
cartstr += '</script>';
cartstr += '<!-- End MyBuys Page Parameters -->';
//alert(cartstr);
var script = document.createElement("script");
script.type = "text/javascript";
script.text = cartstr; // use this for inline script
document.body.appendChild(script);
I want below code added to page:
<!-- MyBuys Page Parameters – Place in <body> element -->
<script type="text/javascript">
mybuys.setPageType("SHOPPING_CART");
mybuys.set("email","consumer#example.com"); <!--consumer email can be blank if not known-->
mybuys.set("amount","99.34");
mybuys.addCartItemQtySubtotal("12345","1","54.34");
mybuys.addCartItemQtySubtotal("56789","3","45.00");
</script>
<!-- End MyBuys Page Parameters -->
This demonstrates how to dynamically add JavaScript:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript">
var optionalFunctionLoaded = false;
var commonFunction = function() {
console.log("test button clicked " + (new Date()).toLocaleString());
if (!optionalFunctionLoaded) {
// get optionalSrc e.g. via AJAX, eventually providing actual input values
var optionalSrc = 'function optFun(){console.log("optional function");}';
// if optionalSrc is not empty
var script = document.createElement("script");
script.innerHTML = optionalSrc;
document.head.appendChild(script);
optionalFunctionLoaded = true;
}
if(optionalFunctionLoaded) optFun();
}
</script>
</head>
<body>
<button id ="testButton">test</button>
<script type="text/javascript">
document.getElementById("testButton").onclick = commonFunction;
</script>
</body>
</html>
Tested with Firefox 24.0 / Linux.
The solution is to just add the code to the page:
<!-- MyBuys Page Parameters – Place in <body> element -->
<script type="text/javascript">
mybuys.setPageType("SHOPPING_CART");
mybuys.set("email","consumer#example.com"); <!--consumer email can be blank if not known-->
mybuys.set("amount","99.34");
mybuys.addCartItemQtySubtotal("12345","1","54.34");
mybuys.addCartItemQtySubtotal("56789","3","45.00");
</script>
<!-- End MyBuys Page Parameters -->
Why use JavaScript to put it there? Just add it to the page. You might have to adjust it a bit with your loop:
for (var i = 0; i < duration.length; i++) {
str = duration[i].value;
var n = str.split('|');
mybuys.addCartItemQtySubtotal(n[0],n[1],n[2]);
}
You should just be executing the code, there is no need to build the string. In the end, what you are trying to do is the same thing as running the code! Just execute it.
mybuys.setPageType("SHOPPING_CART");
mybuys.set("email","consumer#example.com");
mybuys.set("amount","99.34");
for (var i = 0; i < duration.length; i++) {
str = duration[i].value;
var n = str.split('|');
mybuys.addCartItemQtySubtotal(n[0],n[1],n[2]);
}
I don't know why would you want to do that. But if you really want to, here is a way you could try.
$('body').append("console.log('blah');")
OR
$('body').html($('body').html()+"console.log('blah');")
Replace console.log('blah') with your code
Note this is assuming you are using JQuery.
If not, you can still use Native Javascript to do something similar. Just search for creating an element and adding it to another using vanila javascript and you'll get lots of information on google.
Although, as epascarello says, its not a good idea to do this. Its basically a code smell and you can improve your code.
Hope this helps.
