I am trying to look for data-reactid value and replace it with another value.
Here is the code:
Book a Room.
trying to use the code to replace ".0.2.2" with ".0.2.3"
(function () {
var link = document.querySelectorAll('a[data-reactid*=".0.2.2"]') //change example.com to any domain you want to target
var searchString = ".0.2.2" //the string to be searched forEach
var replacementString = ".0.2.3" //the replacement for the searched string
links.forEach(function(link){
var original = link.getAttribute("data-reactid");
var replace = original.replace(searchString,replacementString)
link.setAttribute("data-reactid",replace)
})
})();
Just change this
var link = document.querySelectorAll('a[data-reactid*=".0.2.2"]')
to this
var links = document.querySelectorAll('a[data-reactid*=".0.2.2"]')
But keep in mind that you should not change the attributes set by React itself

I am trying to get a vlaue from a data layer variable and add it to the end of a hyperlink.
So if my hyperlink is https://www.somehyperlink.com and my variable is variable1 with value 23 i want the final hyperlink to be https://www.somehyperlink.com/23.
I've got this code, which is probably not the best way to do it, but I'm not sure how to replace the last part of it with the value from the variable:
(function () {
var links = document.querySelectorAll( 'a[href="https://www.somehyperlink.com/replace"]')
var searchString = "replace"
var replacementString = "value-from-variable"
links.forEach(function(link){
var original = link.getAttribute("href");
var replace = original.replace(searchString,replacementString)
link.setAttribute("href",replace)
})
})();
I would appreciate any help.
Thanks
The code works, try to apply it in a Custom HTML Tag instead Custom Javascript variable.
Step 1:
create a Data Layer Variable called i.e. 'DLV value to replace' and assign the name of the variable in the Data Layer Variable Name field.
Step 2:
apply the Data Layer Variable to your Custom HTML code.
See below:
<script>
var links = document.querySelectorAll( 'a[href="https://www.somehyperlink.com/replace"]')
var searchString = "replace"
var replacementString = {{DLV value to replace}}
links.forEach(function(link){
var original = link.getAttribute("href");
var replace = original.replace(searchString,replacementString)
link.setAttribute("href",replace)
})
</script>
So here we have some url's from same domain:
http://example.com/video6757788/sometext
http://example.com/video24353/someothertext
http://example.com/video243537786/somedifferenttext
http://example.com/video759882
http://example.com/video64353415
http://example.com/video342432?session=somestring
How to get just the numbers part that comes after video in all types of the url's. I'm trying to get the video id's.
First i get the url's, but then how do I get the id's?
var url = $('a[href*="example"]');
var id = ???
Use a regular expression:
$('a[href*="example"]').each(function() {
var $this = $(this);
var url = $this.attr("href");
var id = url.match(/video(\d+)/i)[1]; //retrieve the number following video*
//logic
})
Or if you want to be fancy with .attr(), equivalent would be:
$('a[href*="example"]').attr("href", function(indx, url) {
var id = url.match(/video(\d+)/i)[1]; //retrieve the number following video*
//logic
})
I'm trying to get the link element in a feed, i can get the description and title, but cannot get the link element. It seems weird to me. Here is my code
var url = "http://healthyhow.net/feed";
var response = UrlFetchApp.fetch(url);
var shareDoc = Xml.parse(response.getContentText(), true);
var root = shareDoc.getElement(); // feed element
var entries = root.getElement("channel").getElements("item");
for (var i=0; i<1; i++) { //just pick the first entry
var e = entries[i];
var title = e.getElement("title").getText();
var link = e.getElement("link").getText();
var description = e.getElement("description").getText();
}
Could anyone point out what is wrong here?
Thanks!
The docs indicate you should use lenient parsing for HTML - it's unclear what this is doing underneath, but in your case maybe it's confusing an HTML <link> element with a generic XML element with that same tag name. It appears to parse the link entries into something like this for your code (which you can see in shareDoc.toXmlString()):
<link/>http://healthyhow.net/l-arginine-natural-treatment-for-hypertension/
Since it's an empty tag, no text.
Change:
var shareDoc = Xml.parse(response.getContentText(), true);
to be:
var shareDoc = Xml.parse(response.getContentText(), false);
and you should be able to get the link text.
I want to replace a dynamic url query parameter with another parameter.
Eg. like my url is:
http://www.mysite.com/209-0539.prd?pageLevel=&skuId=111-4567&sc_cmp=pcp_GSF_Batteries+%26+Electrical+Accessories_209-0539
I want to replace everything starting after
&sc_cmp=pcp_GSF_Batteries+%26+Electrical+Accessories_209-0539
and add something like & new Static string
My final url should look like:
http://www.mysite.com/209-0539.prd?pageLevel=&skuId=111-4567& new static string.
Thanks
I recommend you to use the cool URI.js library, then it's as easy as:
var url = "http://www.mysite.com/209-0539.prd?pageLevel=&skuId=111-4567&sc_cmp=pcp_GSF_Batteries+%26+Electrical+Accessories_209-0539";
url = URI(url).removeSearch("sc_cmp").addSearch("newvar","newval");
// http://www.mysite.com/209-0539.prd?pageLevel=&skuId=111-4567&newvar=newval
alert(url);
See working demo .
If you don't want to include another library, following lets you add as many search items you want removed and add as many as you like without a lot of code
/* array of search keys to remove*/
var removeSearch = ['sc_cmp'];
/* array of new search items*/
var newSearchitem = ['image=cool'];
var url = location.href;
var pageUrl = url.split('?')[0];
var urlSearch = url.split('?')[1].split('&');
/* store search items in array */
var newSearchArr = [];
/* loop over exisiting search items and store keepers*/
for (i = 0; i < urlSearch.length; i++) {
var key = urlSearch[i].split('=')[0];
if ($.inArray(key, removeSearch) == -1) {
newSearchArr.push(urlSearch[i])
}
}
$.merge(newSearchArr, newSearchitem);
var newUrl = pageUrl + '?' + newSearchArr.join('&')

I am working on a project in Google Blogger. First i want to explain a thing.
In blogger every post that is created has a unique id assigned to it by blogger itself. This id can be retrieved using Blogger JSON. So i have retrieved the ids of four recent posts using JSON.
I want to wrap these first four id containers around a DIV container using JQuery or Javascript.
The problem is when i use these ids absolutely in the selector $ and use the wrapAll() function the id container's gets wrapped up. But as i said i'm using JSON to get the container id's so the values of ID's are stored in variable's and when i use those variable as selection for wrapAll() function it doesn't work.
I have demos of both those situation's which can be seen by going to this blog http://youblog-demo.blogspot.com/ and using the firebug console to run these code.
Situation 1 when i use absolute container ids
var script = document.createElement("script");
script.src = "http://youblog-demo.blogspot.com/feeds/posts/default?alt=json&callback=hello";
document.body.appendChild(script);
function hello(json){
if(json.feed.entry.length>4){
var post_num=4;
var id_coll = new Array();
for(i=0; i<post_num; i++){
var ids = json.feed.entry[i].id.$t;
var post_id = ids.substring(ids.indexOf("post-"));
var only_id = post_id.substring(5);
id_coll[i] = only_id;
}
$("#3337831342896423186,#123892177945256656,#9095347670334802803,#2525451832509945787").wrapAll('<div>');
}
};
Situation 2 when i use variable's to select the containers
var script = document.createElement("script");
script.src = "http://youblog-demo.blogspot.com/feeds/posts/default?alt=json&callback=hello";
document.body.appendChild(script);
function hello(json){
if(json.feed.entry.length>4){
var post_num=4;
var id_coll = new Array();
var front_name = "#";
for(i=0; i<post_num; i++){
var ids = json.feed.entry[i].id.$t;
var post_id = ids.substring(ids.indexOf("post-"));
var only_id = post_id.substring(5);
id_coll[i] = only_id;
}
var joined_id_0 = String.concat(front_name,id_coll[0]);
var joined_id_1 = String.concat(front_name,id_coll[1]);
var joined_id_2 = String.concat(front_name,id_coll[2]);
var joined_id_3 = String.concat(front_name,id_coll[3]);
$(joined_id_0,joined_id_1,joined_id_2,joined_id_3).wrapAll('<div>');
}
};
So when i use the situation 2 code then it doesn't work but the situation1 code works fine. Can anybody help me with this
You need to pass in the selector as a string, not a list of arguments;
$(joined_id_0+', '+joined_id_1+', '+joined_id_2+', '+joined_id_3).wrapAll('<div>');
Or even better, replace all of:
var joined_id_0 = String.concat(front_name,id_coll[0]);
var joined_id_1 = String.concat(front_name,id_coll[1]);
var joined_id_2 = String.concat(front_name,id_coll[2]);
var joined_id_3 = String.concat(front_name,id_coll[3]);
$(joined_id_0,joined_id_1,joined_id_2,joined_id_3).wrapAll('<div>');
With:
$('#'+id_coll.join(', #')).wrapAll('<div>');
And remove the line: var front_name = '#';
You have to concatenat the ids, separated by a comma, as in #id1, #id2, ....
You can do that this way:
[joined_id_0,joined_id_1,joined_id_2,joined_id_3].join(',')
The whole line:
$([joined_id_0,joined_id_1,joined_id_2,joined_id_3].join(',')).wrapAll('<div>');
If it doesn't works, check the what is returned by [joined_id_0,joined_id_1,joined_id_2,joined_id_3].join(',') (alert() it, or use console.log).
