Is it possible to select an html input element on its current value, using CSS or XPath selectors?
My input control is generated by a React App as
<input name="documents"
placeholder="Documents" required="" type="file" value="">
Or do the document.query… and document.evaluate() functions only query the initially loaded document?
In javascript I can get the current value of an input. But I am trying to write a selector for SeleniumIDE against a React app. My current efforts are
xpath=//input[contains(#value , 'document')]
or
css=input[value*='document']
but whereas I can easily select on name, I'm failing to select by value.
In the browser console I find that
document.querySelector("input[name=documents]").value
gives me a value "C:\fakepath\Upload a document.txt"
but
document.querySelector("input[value*=doc]")
gives me nothing

I am trying to update the value of an input field after the user chooses a selction from autocomplete. I am using typeahead js for autocomplete feature. Here is my jsfiddle
https://jsfiddle.net/aminur/jLa7x28y/7/
<div id="the-basics">
<input class="typeahead" type="text" placeholder="States of USA">
</div>
Once the user selects a state, I want to update the value of the input field to its short form. Like if the user selects Connecticut, I would like to update the display as CT. I tried using oninput, bind functions on the input tag. It didnt work. can you please help?
I have a country picker in my form like this:
<select class="bfh-countries text-left" name="country" id="country" data-country="DE">
</select>
I can get the value with jQuery like this:
$("#country").val()
but when i try to serialize the form with $("#myform").serializeArray() The value for "country" is an empty string.
How can i fix this?
I ran into this problem and it took me forever to find because there aren't any examples of it. What you really want to do is use data-name="country", which names the hidden variable on the back end as country. For the country picker, you can use the div tag as follows:
<div class="country bfh-selectbox bfh-countries" data-flags="true" data-filter="true" data-name="country" data-country="POSTBACK_VARIABLE_GOES_HERE"></div>
If you do this, you'll find a hidden variable that's added to the page as follows:
<input type="hidden" name="country" value="US">
The value above assumes you selected United States but it is entered as a 2 character code, which could then be entered as data-country above if you need to do server-side validation and display the page again without forcing the user to select the value all over again.
This was seriously a nightmare to find.
I encounter a problem when testing form validation with angularjs
According to angularjs form guide,
an input control that has the ngModel directive holds an instance of NgModelController. Such a control instance can be published as a property of the form instance using the name attribute on the input control.
I created test code at plunker, it all works fine untill I change the input name from
<input type="number" name="age" ng-model="user.age" max="100" required>
<p>{{form1.age.$error}}</p>
to
<input type="number" name="user[age]" ng-model="user.age" max="100" required>
<p>{{form1.user[age].$error}}</p>
Does this mean angular can not recognize array syntax in form input?
The problem for me is I want to keep the normal form submission flow and only use angular for form validation, so I need to keep form input as array to work with the backend form handling
It has nothing to do with Angular. It is a syntactic JS error.
If you want to reference a property named user[age], you should do it like this:
form1['user[age]'].$error
form1.user[age] is incorrectly interpreted as (form1.user)[age]
i use Eclipse kepler
in dynamic web project
i create html(HTML5) file and use code for Multi select file upload system
<input type="file" multiple="true" />
but can't select multiple with ctrl+click
and my eclipse has warning
Multiple annotations found at this line :
-Undefined attribute value(true)
-Undefined attribute value(true)
any suggestion?
You need to use the attribute's name as its value:
If the attribute is present, its value must either be the empty string
or a value that is an ASCII case-insensitive match for the attribute's
canonical name, with no leading or trailing whitespace.
(http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes)
In other words, just use:
<input type="file" multiple>
or
<input type="file" multiple="multiple">
If it does not work, then the reason is that you are using a browser that does not support the multiple attribute, such as IE 9. To deal with such browsers, you can add some JavaScript that tests whether the input element has the multiple property and if it does not, creates some additional file input elements (possibly in a loop that lets the user specify any number of files).
The warning should really be an error message, since true is not a valid value for the multiple attribute. As #IlmoEuro explains, the value should be empty or multiple. However, the value has in practice no impact; browsers recognize just the attribute name and ignore the value (even if you write multiple="false" for example).
im pretty new to jQuery, and i dont know how to do that, and if it can be done without editing manually the plugin.
Assume to have a simply form like that:
<form action="page.php" method="post">
Name: <input type="text" name="Your name" id="contact-name" value="" />
Email: <input type="text" name="Your email" id="contact-email" value="" />
</form>
When you submit it, both in 'standard' way or with ajaxSubmit(), the values of the request take the label of the field name, so in the page.php i'll have:
$_POST['Your name'];
$_POST['Your email'];
Instead i'll like to label the submitted values with the id of the field:
$_POST['contact-name'];
$_POST['contact-email'];
Is there a way to do that with jquery and the ajaxsubmit() plugin?
And, maybe, there is a way to do it even with the normal usage of a form?
p.s: yes, i know, i could set the name and id attributes of the field both as 'contact-name', but how does two attributes that contain the same value be usefull?
According to the HTML spec, the browser should submit the name attribute, which does not need to be unique across elements.
Some server-side languages, such as Rails and PHP, take multiple elements with certain identical names and serialize them into data structures. For instance:
<input type="text" name="address[]" />
<input type="text" name="address[]" />
If the user types in 1 Infinite Loop in the first box and Suite 45 in the second box, PHP and Rails will show ["1 Infinite Loop", "Suite 45"] as the contents of the address parameter.
This is all related to the name attribute. On the other hand, the id attribute is designed to uniquely represent an element on the page. It can be referenced using CSS using #myId and in raw JavaScript using document.getElementById. Because it is unique, looking it up in JavaScript is very fast. In practice, you would use jQuery or another library, which would hide these details from you.
It is reasonably common for people to use the same attribute value for id and name, but the only one you need to care about for form submission is name. The jQuery Form Plugin emulates browser behavior extremely closely, so the same would apply to ajaxSubmit.
It's the way forms work in HTML.
Besides, Id's won't work for checkboxes and radio buttons, because you'll probably have several controls with the same name (but a different value), while an HTML element's id attribute has to be unique in your document.
If you really wanted, you could create a preprocessor javascript function that sets every form element's name to the id value, but that wouldn't be very smart IMHO.
var name = $("#contact-name").val();
var email = $("#contact-email").val();
$.post("page.php", { contact-name: name, contact-email: email } );
This will let you post the form with custom attributes.
