I've made a search bar in my web page and I'm trying to get the user input and compare it to a keyword. If it matches, show the user what he is searching for in another page.
The problem is that I don't know how to switch between pages of the HTML using JavaScript (being in page1.html and then take the user to page2.html if the keyword matches).
I've tried to implement href to a function and then running it when the search button is pressed but I haven't found a way to do it.
Here is the code:
<script>
let search = getElementById("Search").value;
if (search == "Keyword") {
//a href="page2.html" - (this is was my main idea, but i haven't found a way to implement it correctly)
}
</script>
First, you have to get the value from the input that you create and then you have to compare between the value that you get it and the specific keyword that you want, and after that, you have to create a button to submit with it. Then you can try this line
window.location.href=“./Page2.htm”;
inside if condetion.
try with:
window.location.href=“./Page2.htm”;
You can use
window.open(stringURL);
to open the html in a new window.
To open a new tab:
window.open(stringURL, “_blank”);

I'm using cefsharp and vb.net to put some code together to move to the next page of this site:
https://www.recommendedagencies.com/search#{}
The idea is to read the list of company names on each page and store to a csv file. This part I can do.
The problem I have is that I can't find the name of the 'Next' button - presumably if I had that I could execute some javascript on the browser to press the button.
I've inspected the page in Firefox, but can't see any name I can use - I'm not really familiar enough with html/page design to know why not or how it works.
Could anyone tell me a good method to get button names from a web page? - I've done some searching and even asked a similar question myself before, but I can't find anything which helps, given my patchy knowledge.
Thanks
Inspect the DOM for the 'Next' button.
Look for id's or classes that you can use to identify it.
use document.querySelector() to find the element by the css selector
call the element.click() function to programatically press next
const nextButton = document.querySelector('.sp-pages-nav_next')
nextButton.addEventListener('click', (event) => {
console.log('something clicked next')
})
nextButton.click()
<div class="sp-pages-nav sp-pages-nav_next" data-reactid=".1.3.4.1">Next</div>
In the above snippet on load you can see the code nextButton.click() invokes the console log. You can click the word Next manually to the same effect.
in cefsharp perhaps something like:
browser.ExecuteJavaScriptAsync("(function(){ document.querySelector('.sp-pages-nav_next').click(); })();");
A very similar example can be found here :
https://github.com/cefsharp/CefSharp/wiki/General-Usage#1-how-do-you-call-a-javascript-method-from-net
// When executing multiple statements, group them together in an IIFE
// https://developer.mozilla.org/en-US/docs/Glossary/IIFE
// For Google.com pre-populate the search text box and click the search button
browser.ExecuteJavaScriptAsync("(function(){ document.getElementsByName('q')[0].value = 'CefSharp Was Here!'; document.getElementsByName('btnK')[0].click(); })();");
I'm trying to find code or a way to process the following:
When you click a button a site it'll go and read specific website link and then return variables that it finds in the remote page.
1) user clicks button
2) query goes to www.whatever.com/myfile.html
3) there is a specific p tag inside a div tag called 'totalamount' = <div id=WTextWrapper><p id="Amount">2,000</p></div> That I want to grab the value of and then display it on my page below the button that I clicked in step 1
I know there is a way to do it, but I have no idea how it's done.
You need to get the source of the html and use regex to extract what you need. You can use file_get_contents() function to get the source html.
Is it possible to alter the url of a webpage so that it will activate specific click-activated features on the webpage without the user having to do the clicking?
To better illustrate my question I made this fiddle.
The page loads with a red box with information in it. The user can click the box once to see new information. They can click it again to see a third piece of information.
I would like to have urls that load the page with specific information showing. For example, if the main url for my page is http://www.mypage.com, then I would like to have urls http://www.mypage.com/#info2 and http://www.mypage.com/#info3 so that when the user enters the info2 (respectively, info3) url, the page loads with the second (respectively, third) piece of information showing.
Remarks: I have searched some other questions about activating scripts with hashtags, but have not found something I can understand or implement into what I want to do. In particular, I need my hashtag urls to be able to implement a sequence of several actions (e.g. two clicks to get info3 in the above example).
Remark 2: I am open to other solutions too. I just need someone to explain how to accomplish what I am trying to do.
You could use this after you define your click handlers.
if (window.location.hash == '#1'){
$("#info1").click();
}
if (window.location.hash == '#2'){
$("#info1").click();
$("#info2").click();
}
Not sure if any of this works -- I didn't devote much time on it, given the state of the question, but consider:
var hash_page = (window.location.hash+'').replace(/^#/,''); // get hash and parse
var page_number = hash_page.match(/\w+?(\d+)/)[1] || 1; // get the number
var next_page = page_number + 1; // get next number
$('#info'+page_number).click(function(){
window.location.hash = 'info' + next_page;
});
Assuming that your red box is a div like this:
<div class="redbox">...</div>
and that you have three blocks within it (info 1, 2, and 3):
<div class="redbox">
<div class="info1">...</div>
<div class="info2">...</div>
<div class="info3">...</div>
</div>
With jQuery you could do something simple like this:
jQuery(".redbox").click(function()
{
if(jQuery(".redbox .info3").is(":visible"))
{
return; // all done already
}
if(jQuery(".redbox .info2").is(":visible"))
{
jQuery(".redbox .info3").show();
return;
}
jQuery(".redbox .info2").show();
});
I'm not too sure why you'd like that in the URI. The only reason for such would be in case the user comes back to that same place and you'd want them to see the page in the same state. If that is important, then yes, you should use the window.location.hash to change the URI. That way, if the user comes back you can test the hash and setup the status as required on load. However, note that the hash does not get sent to the server. It is only a client thing.
My solution supposes that info2 and info3 are already loaded. It is also possible to use the load() function to load them dynamically. It depends on their size and whether you do or do not want that information to be visible when the user does "Show Source".
There is the reason why some systems use the "hashbang" feature in their website:
https://developers.google.com/webmasters/ajax-crawling/
Google, at some point, said they would drop that functionality, but it looks like they have not done so and actually continue to encourage people to use that methodology. Twitter has been using it for a while, but from what I can see they don't use it anymore.
The code below saves data entered in textarea using saveFieldData().I want to use a Delete Button as a bookmarklet which will make this field blank and save the same in the server.
<textarea rows="4" cols="49" name="Synonym" id="Synonym" onchange="saveFieldData(85261, this, 'docProductInfo', 'Synonym', 84796);"></textarea>
So here is my bookmarklet
javascript:(function(){var sy=document.getElementById("Synonym");sy.value="";saveFieldData(85261,sy, 'docProductInfo', 'Synonym', 84796);})();
It deletes the data perfectly but the problem is whenever the page reloads it assigns some new values as function parameters as a result my code fails to work.For example after page reloads the function parameter changes like this
saveFieldData(85261, this, 'docProductInfo', 'Synonym', 84789);
basically the last parameter changes.So,Is there any way so that my bookmarklet will detect that parameter automatically and delete that field successfully?
If you just need to invoke the onchange handler you don't need to know it's parameters:
var sy=document.getElementById("Synonym");
var fn=sy.onchange;
sy.value="";
fn.call(sy);
Or more simply, since the onchange handler doesn't use any this within it:
fn();
Without knowing more about your page, I can't give you an ideal answer. There could easily be a better way, but based only on what you have shown, the only answer I see is to use a regular expression something like this:
sy = document.getElementById("Synonym");
id = sy.onchange.toString().match(/saveFieldData\(.+?,.+?,.+?,.+?,\s*(\d+)\)/)[1];
I am trying to create a Javascript function to display a dynamic confirmation message, that will appear on a confirm.html page. It needs to be in an external Javascript file so that it can be used on a variety of pages. I've tried a variety of things but I just cant quite get it to work correctly. I'm trying to do it with only Javascript.
This is what I have currently, after doing some research
This is button I'm using to call the function
<input type="button" value="Remove" onclick="dynamicMessage('This product has been deleted')">
and the current function I'm using is
function dynamicMessage(argument)
{
var test = window.open("./confirm.html","_self");
test.document.write("test");
test.document.close();
}
Obviously, the dynamic content isn't added in yet, but if my thinking is correct, it should just be adding the argument somewhere in the long string of html I need to add to create the page. The "test is just do see what happens when calling the function.
What I want it to do is, write the "test" to the new window of confirm.html, but instead it overwrites the current window. But if I only call window.open, it opens to the correct window. It is the document.write part that is throwing me off.
I'm not sure if I'm far off base on my thinking, or if its just a simple mistake I'm missing after hours of looking at this code. Any Ideas?
I think I need to clarify what I am trying to do. I am trying to click a button, in this case a remove button, then open up the page confirm.html, edit the content in confirm.html with the argument, and have the current page now be confirm.html. What currently happens is one of two things either the current document is edited if the "_self" tag is placed, or the html page is open and thus an about_blank url.
Hope i understood your question | DEMO
Since you are using document.write method it will overwrite contents of your html page
function dynamicMessage(argument)
{
var test = window.open("./confirm.html","_blank");
test.document.write(argument);
setTimeout(function(){test.close()},2000); // after 2 sec it will close
}
