I am mostly familiar with java selenium, and I am new to both JS and Protractor. Lets say I am trying to click an option from a list of options with a common identifier..
var options = $('.options');
How could I get all elements with that common identifier, and then select one by its text? I can not do driver.findElements like I could in java since there is no reference to driver..
This is what I have tried so far but its not working and I think its due to my inexperience with JS
this.selectCompanyCode = function(companyCode) {
dropDownMenus[0].click();
var companyCodeOptions = $('[ng-bind-html="companyCode"]');
companyCodeOptions.filter(function (elem) {
return elem.getText().then(function text() {
return text === companyCode;
});
}).first().click();
};
Select all elements with common identifier: $$('.options'); That selects all elements with a class of .options -- equivalent of element.all(by.css('.options')). This returns an ElementArrayFinder. Also see .get() for how to choose an element by index from the ElementArrayFinder.
Find by text, you could use cssContainingText(css, text). For example,
var loginBtn = element(by.cssContainingText('button.ng-scope', 'Login'));
But if for some reason those are not providing the expected results, you can use .filter() (docs here) on an ElementArrayFinder to go through the array of elements and find an element based on a condition you specify. For example,
var allOptions = $$('.options');
allOptions.filter(function (elem) {
return elem.getText().then(function (text) {
return text === 'What you want';
});
}).first().click();
And, although I've never used regular Java Selenium (so I don't know if this is the same), but there is indeed a browser reference (and therefore findElements function): http://www.protractortest.org/#/api?view=ProtractorBrowser.
Hope it helps!
Edit:
Using your code:
this.selectCompanyCode = function(companyCode) {
// where is dropDownMenus defined? This has function no reference to it.
dropDownMenus.get(0).click(); // should be this
var companyCodeOptions = $$('[ng-bind-html="' + companyCode + '"]');
return companyCodeOptions.filter(function (elem) {
return elem.getText().then(function text() {
return text === companyCode;
});
}).first().click();
};
second edit:
Assuming company code is unique, you probably don't need to use filter. Try this:
this.selectCompanyCode = function(companyCode) {
dropDownMenus.get(0).click();
var companyCodeOptions = $('[ng-bind-html="' + companyCode + '"]');
return companyCodeOptions.click();
};
Use cssContainingText
element(by.cssContainingText(".option", "text")).click();

I have two the same forms on the same page and script that works only for the first form.
I'm a beginner and this is a challenge for me; I tried add the `for (var i = 0; i < input.length; i++) but it doesn't work out. I will be grateful for any help.
var el = document.querySelector(".js-tac");
input = document.querySelector('.js-tel')
input.addEventListener('input', evt => {
const value = input.value
if (!value) {
el.classList.remove("is-visible");
return
}
const trimmed = value.trim()
if (trimmed) {
el.classList.add("is-visible");
} else {
el.classList.remove("is-visible");
}
})
document.querySelector return the first matched element. So you need document.querySelectorAll which will give a collection. Then iterate that collection like this
document.querySelectorAll('.js-tel').forEach((input)=>{
// not using arrow function since using this to target the element
input.addEventListener('input', function(evt){
const value = this.value
// rest of the code
})
})
The problem is that you are only getting one input element. (querySelector returns the first matching element, not all matching elements). You likely want to use querySelectorAll to get a NodeList (which will contain all matching nodes). You can iterate over those.
Based on how you seem to be using it, I'd recommend making sure your js-tac and js-tel are wrapped in some common parent, and use querySelectorAll to find those. Then, you can use querySelector to find the js-tel and js-tac.
var nodes = document.querySelectorAll('.js-parent')
//If you don't export forEach to be available, you can also just do a standard
//for loop here instead.
nodes.forEach((parent) => {
var el = parent.querySelector(".js-tac");
input = parent.querySelector('.js-tel')
...
})
This question already has answers here:
this.href vs $(this).attr('href')
(3 answers)
Closed 5 years ago.
I wrote a little function which basically says to check if some text is exactly this or that:
function doSelect(text) {
return $wikiDOM.find(".infobox th").filter(function() {
return $(this).text() === text;
});
}
The I run this in order to get the last string after /wiki/ of some links like Geum River, Korea
let pattern = new RegExp('^\/wiki\/');
doSelect("Location").siblings('td').find('a').map(function(i, el) {
return console.log(el.href.replace(pattern, ''));
});
But when I check in console I get the whole jsFiddle link
https://fiddle.jshell.net/wiki/Geum_River
https://fiddle.jshell.net/wiki/Korea
I'd expect
Geum_River
Korea
The issue is because you're using the href attribute of the <a>. By doing this you retrieve the full absolute path of the URI, ie: https://fiddle.jshell.net/wiki/Geum_River instead of the relative path: /wiki/Geum_River
To change this behavior, use the attribute value directly, using attr():
let pattern = new RegExp('^\/wiki\/');
doSelect("Location").siblings('td').find('a').map(function(i, el) {
var result = $(this).attr('href').replace(pattern, '');
console.log(result);
return result;
});
Also double check that you're using map() correctly. It's intention is to create an array, but you're not doing anything with it's response. It would be worth using each() instead without the return if all you want to do is loop through the selected elements:
let pattern = new RegExp('^\/wiki\/');
doSelect("Location").siblings('td').find('a').each(function(i, el) {
var result = $(this).attr('href').replace(pattern, '');
console.log(result);
});
You can also try like this:
//let pattern = new RegExp('^\/wiki\/');
doSelect("Location").siblings('td').find('a').each(function(i, el) {
var name = $(this).attr('href').split('wiki/')[1].trim();
console.log(result);
});
Please check out this Fiddle Example. It searches for strings that contain "Glucosamine". How can I strip out "Glucosamine" and add an "&" if it returns two strings, like this:
A Item
Sulfate
B Item
Sulfate & HCl
I got an undefined error using .replace("Glucosamine","") after append.
JSON:
[{"title":"A","Ingredient":"Glucosamine Sulfate,Vitamin C"},{"title":"B","Ingredient":"Vitamin D,Glucosamine Sulfate,Glucosamine HCl,Vitamin A"}]
Code:
$.ajax({
url: "text.json",
success: function (data) {
$(data.query.results.json.json).each(function (index, item) {
var title = item.title;
var ingredients = item.Ingredient;
ingredients = ingredients.split(",");
$.each(ingredients,function(i,ingredient){
if (ingredient.indexOf("Glucosamine") >= 0) {
$('.' + title+'glu').append('<h5>'+ingredient+'</h5>')
}
});
});
},
error: function () {}
});
HTML:
<h3>A Item</h3>
<div class="Aglu"></div>
<h3>B Item</h3>
<div class="Bglu"></div>
Answer
The problem is that you are trying (as far as I can tell) to use replace on the jQuery object like so:
// this will not work
$('.' + title+'glu').append('<h5>'+ingredient+'</h5>').replace("Glucosamine","");
The problem is that replace() is a function of the String object in javascript and there is no replace method in the jQuery object. What you want to do is run replace() against the ingredient variable which is a string.
// this will work
$('.' + title+'glu').append('<h5>'+ingredient.replace("Glucosamine","")+'</h5>');
Not answer
However, based on your latest comment, I don't believe this will actually help you. Although it's unrelated to the actual problem you were having, I'll go ahead and quick put down here how I would approach what you are actually trying to do. I would write your function this way:
$(data.query.results.json.json).each(function (index, item) {
var title = item.title;
var ingredients = item.Ingredient;
// this is good. I like the use of split here
ingredients = ingredients.split(",");
// here I would just filter the array. Don't bother with indexOf.
// You can just as easily use regex. I've chosen to use an
// actual regex pattern but you can also use something like this
// just as easily: ingredient.match("Glucosamine");. I just
// chose to use regex for the sake of using i for case insensi-
// tivity. glucosamineBased is now an array of only the glucose
// ingredients
var glucosamineBased = ingredients.filter(function(ingredient){
return ingredient.match(/glucosamine\s/i);
});
// now that we know which ones are actually glucose based, we
// don't need to itterate through them. Instead we can just jump
// on combining them. I use join which works the opposite as
// split above. After they are joined into one big happy string,
// I strip out the glucosamine words. Easy-peasy. Just keep in
// mind that you need g for global (don't just replace the first
// one, but replace all instances of the pattern) and maybe i for
// case insensitivity.
$('.' + title+'glu').append('<h5>' +glucosamineBased.join(' & ').replace(/glucosamine\s/gi, '')+'</h5>');
});
Hope this helps.
Demo
http://jsfiddle.net/HANvQ/
(oops... forgot the demo)
It's trickier to add the ampersand if the array contains more than one instance of the word "Glucosamine", but the following should do the trick:
$(data.query.results.json.json).each(function (index, item) {
var title = item.title;
var ingredients = item.Ingredient;
ingredients = ingredients.split(",");
var string = '';
$.each(ingredients, function (i, ingredient) {
if (ingredient.indexOf("Glucosamine") >= 0) {
ingredient = ingredient.replace("Glucosamine","");
string += (string.length == 0) ? ingredient : " & "+ingredient;
}
});
$('.' + title + 'glu').append('<h5>' + string + '</h5>')
});

I am using jQuery Serialize to serialize my form elements and would like to deserialize them back. Unfortunately can't find any working jQuery deserializer, any suggestions?
I wrote a version of jQuery.deserialize that supports serialized data generated from the serialize, serializeArray and serializeObject functions. It also supports all form element types, including checkboxes and radio buttons.
Try this:
function deparam(query) {
var pairs, i, keyValuePair, key, value, map = {};
// remove leading question mark if its there
if (query.slice(0, 1) === '?') {
query = query.slice(1);
}
if (query !== '') {
pairs = query.split('&');
for (i = 0; i < pairs.length; i += 1) {
keyValuePair = pairs[i].split('=');
key = decodeURIComponent(keyValuePair[0]);
value = (keyValuePair.length > 1) ? decodeURIComponent(keyValuePair[1]) : undefined;
map[key] = value;
}
}
return map;
}
I was very interested in trying JQuery.deserialize, but it didn't seem to handle checkboxes at all, so it didn't serve my purposes. So I wrote my own. It turned out to be easier than I thought, because the jQuery val() function does most of the work:
jQuery.fn.deserialize = function (data) {
var f = this,
map = {},
find = function (selector) { return f.is("form") ? f.find(selector) : f.filter(selector); };
//Get map of values
jQuery.each(data.split("&"), function () {
var nv = this.split("="),
n = decodeURIComponent(nv[0]),
v = nv.length > 1 ? decodeURIComponent(nv[1]) : null;
if (!(n in map)) {
map[n] = [];
}
map[n].push(v);
})
//Set values for all form elements in the data
jQuery.each(map, function (n, v) {
find("[name='" + n + "']").val(v);
})
//Clear all form elements not in form data
find("input:text,select,textarea").each(function () {
if (!(jQuery(this).attr("name") in map)) {
jQuery(this).val("");
}
})
find("input:checkbox:checked,input:radio:checked").each(function () {
if (!(jQuery(this).attr("name") in map)) {
this.checked = false;
}
})
return this;
};
You should be able to use this like this:
$("#myform").deserialize(data);
Where data is a parameter list such as what $("#myform").serialize() would produce.
It affects all fields in the form, and it will clear the values of fields that are not contained in the data. But you can also pass any selector to affect only specific fields, as you can with the serialize function. E.g.:
$("select").deserialize(data);
Half of jQuery Serialize is param(), so half of something that deserializes a query string is going to be a deparam. Unfortunately I haven't been able to find a good standalone deparam. For now I recommend getting the jQuery BBQ library and using that. If you don't need the other stuff you can remove them. I read somewhere that Ben Alman (cowboy) planned to extract deparam into its own module.
For the rest of deserializing, you'll just need to loop through the object that deparam returns and for each key and value pair in the object, select the form element based on the key, and set the form elements value to the value.
Bit late on this one, but somebody might find this useful.
function fetchInput(identifier) {
var form_data = identifier.serialize().split('&');
var input = {};
$.each(form_data, function(key, value) {
var data = value.split('=');
input[data[0]] = decodeURIComponent(data[1]);
});
return input;
}
I'm not now answering your question but my guess is that you want to serialize it and send back to server and then use the serialized data which is why you have to deserialize it?
If that's the case you should consider using .serializeArray(). You can send it as POST data in ajax, and then access later as well because you will have object.
May be a bit late, but perhaps you are looking for something like JQuery.deserialize. Problems: no support for checkboxes or radio buttons.
Using Jack Allan's deparam function with jQuery, you can change this line:
map[key] = value;
to
$('input[name=' + key + ']').val(value);
Which will load the data back into your form fields.
this code returns an array when same key is spotted multiple times in the serialized string
chaine="single=Single1&multiple=Multiple&multiple=Multiple1&multiple=Multiple2&multiple=Multiple3&check=check2&radio=radio1"
function deserialize(txt){
myjson={}
tabparams=chaine.split('&')
var i=-1;
while (tabparams[++i]){
tabitems=tabparams[i].split('=')
if( myjson[decodeURIComponent(tabitems[0])] !== undefined ){
if( myjson[decodeURIComponent(tabitems[0])] instanceof Array ){
myjson[decodeURIComponent(tabitems[0])].push(decodeURIComponent(tabitems[1]))
}
else{
myjson[decodeURIComponent(tabitems[0])]= [myjson[decodeURIComponent(tabitems[0])],decodeURIComponent(tabitems[1])]
}
}
else{
myjson[decodeURIComponent(tabitems[0])]=decodeURIComponent(tabitems[1]);
}
}
return myjson;
}
Needed all in a single string, which can be stored in maybe COOKIE, and later read and fill the same form with input values.
Input elements seperator: ~ (use any seperator)
Input attributes seperator: | (use any seperator)
input type | input name | input value ~ input2 type | input2 name | input2 value
var formData = '';
$('#form_id').find('input, textarea, select').each(function(i, field) {
formData += field.type+'|'+field.name+'|'+field.value+'~';
});
Example:
hidden|vote_id|10~radio|option_id|~radio|option_id|427~radio|option_id|428~
If what you want is to remove the standard URL-encoded notation, you can use JavaScript's decodeURIComponent(), which will give you a regular string, just like this:
var decodedString = decodeURIComponent("Http%3A%2F%2FHello%3AWorld");
alert(decodedString);
In this case, decodedString will look like Http://Hello:World, here's a working fiddle.
Got all of this searching for this same issue, and found the answer here: How can I decode a URL with jQuery?
I know this is an old question, but doing some searches for jQuery deserialize got me here, so I might as well try to give a different approach on the issue for people with the same problem.
I want to loop over the elements of an HTML form, and store the values of the <input> fields in an object. The following code doesn't work, though:
function config() {
$("#frmMain").children().map(function() {
var child = $("this");
if (child.is(":checkbox"))
this[child.attr("name")] = child.attr("checked");
if (child.is(":radio, checked"))
this[child.attr("name")] = child.val();
if (child.is(":text"))
this[child.attr("name")] = child.val();
return null;
});
Neither does the following (inspired by jobscry's answer):
function config() {
$("#frmMain").children().each(function() {
var child = $("this");
alert(child.length);
if (child.is(":checkbox")) {
this[child.attr("name")] = child.attr("checked");
}
if (child.is(":radio, checked"))
this[child.attr("name")] = child.val();
if (child.is(":text"))
this[child.attr("name")] = child.val();
});
}
The alert always shows that child.length == 0. Manually selecting the elements works:
>>> $("#frmMain").children()
Object length=42
>>> $("#frmMain").children().filter(":checkbox")
Object length=3
Any hints on how to do the loop correctly?
don't think you need quotations on this:
var child = $("this");
try:
var child = $(this);
jQuery has an excellent function for looping through a set of elements: .each()
$('#formId').children().each(
function(){
//access to form element via $(this)
}
);
Depending on what you need each child for (if you're looking to post it somewhere via AJAX) you can just do...
$("#formID").serialize()
It creates a string for you with all of the values automatically.
As for looping through objects, you can also do this.
$.each($("input, select, textarea"), function(i,v) {
var theTag = v.tagName;
var theElement = $(v);
var theValue = theElement.val();
});
I have used the following before:
var my_form = $('#form-id');
var data = {};
$('input:not([type=checkbox]), input[type=checkbox]:selected, select, textarea', my_form).each(
function() {
var name = $(this).attr('name');
var val = $(this).val();
if (!data.hasOwnProperty(name)) {
data[name] = new Array;
}
data[name].push(val);
}
);
This is just written from memory, so might contain mistakes, but this should make an object called data that contains the values for all your inputs.
Note that you have to deal with checkboxes in a special way, to avoid getting the values of unchecked checkboxes. The same is probably true of radio inputs.
Also note using arrays for storing the values, as for one input name, you might have values from several inputs (checkboxes in particular).
if you want to use the each function, it should look like this:
$('#formId').children().each(
function(){
//access to form element via $(this)
}
);
Just switch out the closing curly bracket for a close paren. Thanks for pointing it out, jobscry, you saved me some time.
for me all these didn't work. What worked for me was something really simple:
$("#formID input[type=text]").each(function() {
alert($(this).val());
});
This is the simplest way to loop through a form accessing only the form elements. Inside the each function you can check and build whatever you want. When building objects note that you will want to declare it outside of the each function.
EDIT
JSFIDDLE
The below will work
$('form[name=formName]').find('input, textarea, select').each(function() {
alert($(this).attr('name'));
});
