On my razor view, I am wanting to put all of my jQuery into a separate JS file and then reference that file on the view with #Scripts.Render.
On my view, I have a section jQuery that looks like this:
var settings = {};
settings.baseUri = '#Request.ApplicationPath';
var submissionUrl = "";
if (settings.baseUri === "/ProjectNameOnServer") {
submissionUrl = settings.baseUri + "/api/apiControllerName/apiControllerMethodName/";
} else {
submissionUrl = settings.baseUri + "api/apiControllerName/apiControllerMethodName/";
}
This section of code allows me to test submitting forms with api on both my localhost and live on the server without me having to change the url.
If I am testing on my localhost, then #Request.ApplicationPath == /, but if I test on my server then #Request.ApplicationPath == /ProjectNameOnServer.
I was wondering how I could achieve getting these same values but without the use of Razor, and instead only with jQuery.
I have tried:
var settings = {};
settings.baseUri = window.location.protocol + "//" + window.location.host;
but then settings.baseUri == http://localhost:xxxxx. I just need exactly what #Request.ApplicationPath is giving me.
Use location.host to conditionally create relative path
settings.baseUri = location.host.includes('localhost') ? '/' : '/ProjectNameOnServer';
I'm still new to Node.js, but I'll try to explain my problem as good as I can.
So I'm working on a movie site to practice my node.js/express skills a bit and I use the following elements (img) on basically every page of my website:
Header with stats and search input and a navigation bar (will be reused on every page)
The follow JS-code are two examples of actions on the client side that I use to navigate to other web pages, this then activates GET on the client side.
$(function () {
$('button').click(function (event) {
event.preventDefault()
// the value people enter in the search box
var search = $('.searchInput').val();
//replace spaces with _
var res = search.replace(/\s/g, "_");
//build the URL
var link = window.location.protocol + '//' + window.location.host + '/search/' + res;
// redirect to trigger GET in indexjs with specific search value
window.location.replace(link);
});
$('.lists').click(function (event) {
var link = window.location.protocol + '//' + window.location.host + '/lists/topAll';
window.location.replace(link);
})
});
I want this to be the same code on every page. I could type the same code every time, but that would be a waste of time.For HTML and CSS I am able to use templates (HTML) or import other CSS files to save time. Is there something similar for JS on the client side?
Put that code in a file, for example "navigator.js" and then load it in your html header in every page you want to use it
navigator.js:
$(function () {
$('button').click(function (event) {
event.preventDefault()
// the value people enter in the search box
var search = $('.searchInput').val();
//replace spaces with _
var res = search.replace(/\s/g, "_");
//build the URL
var link = window.location.protocol + '//' + window.location.host + '/search/' + res;
// redirect to trigger GET in indexjs with specific search value
window.location.replace(link);
});
$('.lists').click(function (event) {
var link = window.location.protocol + '//' + window.location.host + '/lists/topAll';
window.location.replace(link);
})
});
index.html
<script src="navigator.js"></script>
Finally i suggest you to assign an id to your button, for example "searchButton" instead only "button"
Hope this helps
Is there a way to make an a tag link that includes part of the current url?
I would use it to change language but stay on the current page!
If I am on:
www.mysite.com/contact
and I press on:
<a>FR</a>
the generated link would be:
www.mystie.com/fr/contact
Kind regards
Try this:
HTML:
FR
Now get the url from javascript
$("#myLink").click(function(e){
e.preventDefault();
var url = document.url; // get current page url
url = url.substr(0, url.indexOf('/')); // get substring from url
url += "/" + $(this).attr("href"); // add href of a tag to url
window.location.href = url; // locate the page to url
});
you can try with some like
function changeLng(lang) {
// remove language '/fr/' or '/es/' if exists
var path = window.location.pathname.replace(/\/[a-z]{2}/, '');
// reload the page same url with the lang prefix
window.location.href = '/' + lang + path;
}
the link can be
FR
ES
EN
this converts any url to lang specific, sample
/contact to /fr/contact
/about to /fr/about
update
for remove the lang part is simple
function removeLng() {
// remove language
var path = window.location.pathname.replace(/\/[a-z]{2}/, '');
window.location.href = path;
}
Is there a way to save the current webpage by using casperjs or phantomjs?
I tried to get the html and save it into a file. But the resulting file was a lot different from the screenshot of that time (with casper.capture). Is there a way to save the current webpage?
Andrey Borisko suggested to use the disk cache to retrieve the resources. My solution is not that efficient, but you don't need to decompress text files.
I use XMLHttpRequest to retrieve all resources after I registered them with the resource.received event handler. I then filter the resources into images, css and fonts. The current limitation is that remote resource paths that contain something like ../ or ./ are not handled correctly.
I retrieve the current page content with getHTML and iterate over all captured resources to replace the path used in the markup, that is identified by a portion of the complete resource URL, with a randomly generated file name. The file extension is created from the content type of the resource. It is converted using mimeType from this gist.
Since CSS files may contain background images or fonts, they have to be processed before saving to disk. The provided loadResource function loads the resource, but does not save it.
Since XMLHttpRequest to download the resources the script has to be invoked with the --web-security=false flag:
casperjs script.js --web-security=false
script.js
var casper = require("casper").create();
var utils = require('utils');
var fs = require('fs');
var mimetype = require('./mimetype'); // URL provided below
var cssResources = [];
var imgResources = [];
var fontResources = [];
var resourceDirectory = "resources";
var debug = false;
fs.removeTree(resourceDirectory);
casper.on("remote.message", function(msg){
this.echo("remote.msg: " + msg);
});
casper.on("resource.error", function(resourceError){
this.echo("res.err: " + JSON.stringify(resourceError));
});
casper.on("page.error", function(pageError){
this.echo("page.err: " + JSON.stringify(pageError));
});
casper.on("downloaded.file", function(targetPath){
if (debug) this.echo("dl.file: " + targetPath);
});
casper.on("resource.received", function(resource){
// don't try to download data:* URI and only use stage == "end"
if (resource.url.indexOf("data:") != 0 && resource.stage == "end") {
if (resource.contentType == "text/css") {
cssResources.push({obj: resource, file: false});
}
if (resource.contentType.indexOf("image/") == 0) {
imgResources.push({obj: resource, file: false});
}
if (resource.contentType.indexOf("application/x-font-") == 0) {
fontResources.push({obj: resource, file: false});
}
}
});
// based on http://docs.casperjs.org/en/latest/modules/casper.html#download
casper.loadResource = function loadResource(url, method, data) {
"use strict";
this.checkStarted();
var cu = require('clientutils').create(utils.mergeObjects({}, this.options));
return cu.decode(this.base64encode(url, method, data));

// TODO: remove all event handlers in html
var page = this.getHTML();

var css = casper.loadResource(cssResource.obj.url, "GET");
css = findAndReplace(css, imgResources);
css = findAndReplace(css, fontResources);
fs.write(cssResource.file, css, "wb");

}
casper.start("http://www.themarysue.com/").wait(3000).then(capturePage).run(function(){
this.echo("DONE");
this.exit();
});
The magic happens in findAndReplace. capturePage is completely synchronous so it can be dropped anywhere without much head ache.
URL for mimetype.js
No, I don't think there is an easy way to do this as phantomjs doesn't support rendering pages in mht format (Render as a .mht file #10117). I believe that's what you wanted.
So, it needs some work to accomplish this. I did something similar, but i was doing it the other way around I had a rendered html code that I was rendering into image/pdf through phantomjs. I had to clean the file first and it worked fine for me.
So, what I think you need to do is:
strip all js calls, like script tags or onload attributes, etc..
if you have access from local to the resources like css, images and so on (and you don't need authentication to that domain where you grab the page) than you need to change relative paths of src attributes to absolute to load images/etc.
if you don't have access to the resources when you open the page then I think you need to implement similar script to download those resources at the time phantomjs loads the page and then redirect src attributes to that folder or maybe use data uri.
You might need to change links in css files as well.
This will bring up the images\fonts and styling you are missing currently.
I'm sure there are more points. I'll update the answer if you need more info, once I see my code.
In my db I have saved every links in the form:
www.example.com or http://www.example.com
Is there a way to turn this text links into HTML links at the client side ( e.g. javascript ) with tag and parameter like this ?:
www.example.com
This would probably be smarter to do on the server side like cherouvim suggested, but here's a (naive) javascript function that does this for the specified formats (url with and without http://-prefix)
function makeLink(link) {
var url, desc;
if (link.match('^http://')) {
url = link;
desc = link.substr(7, link.length - 7);
} else {
url = 'http://' + link;
desc = link;
}
return '' + desc + '';
}
Please note it doesn't handle unexpected input (https...) very well, so please don't use as-is in production environment :)
I would try it like this:
text.replace(/([A-Za-z]+:\/\/)?[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&\?\/.=]+/, function(url) {
return url.link(url);
})
