I have a basic form input for a number. The form works. The field will not accept letters being type into it. But the increment arrows that usually show up for type="number" aren't showing up. What am I missing?
<div>
<input
type="number"
id="cost"
className="form-field"
placeholder="Cost"
min="0"
onChange={handleChange}
value={hats.cost}/>
</div>

Is there a way to perform checks on input attributes like you can for forms?

I'm trying to get the "Enter a small number" text to appear if a number larger than max was typed
<div class="ui input right labeled">
<input type="number"
placeholder="{{ vm.object.objectTitle }}"
step="any"
min="1"
max="1000"
ng-model="vm.object.model"
ng-change="vm.inputChanged()"
name="inputFieldName">
</div>
<div ng-if="inputFieldName.$error.max"
style="color:red">
Enter a smaller number
</div>
how can I achieve that the parameters from the input elements range, are only submitted via GET-Request if the user interacts with the range slider before submitting. So that when the form is submitted the default values are not always submitted?
<div data-role="rangeslider">
<label for="range-1a">Rangeslider:</label>
<input type="range" name="absMin" id="rangeMin" min="0" max="1" value="0" step="0.1">
<label for="range-1b">Rangeslider:</label>
<input type="range" name="absMax" id="rangeMax" min="0" max="1" value="1" step="0.1">
</div>
Thanks a lot in advance
there're many ways to do that, maybe the easiest way is changing your slider's initial value to -1, but why you do that? what if your user actually want to choose but they don't do the slide because they feel like the slider already showed the value they wanted?
Is there a way to have a form that holds a pre set value (numbers or letters) that cant be changed by the user and isnt hidden to them. I need to so when someone clicks on a product the product id and price is auto filled out, they only need to type in the quantity.
I think you can set the value on the HTML form <input> using the value attribute as always and disable the input by using the disabled html attribute.
Something like this:
<form action="/action_page.php">
First name:
<input type="text" name="fname" value="John" disabled ><br>
Last name:
<input type="text" name="lname" value="Doe"><br>
<input type="submit" value="Submit form">
</form>
the value will be there and the field will be disabled.
Hope it helps,
The code shown below will prevent the user from entering any value in input type. Is there a way the box can be hidden in this case.
<input id="vendor" name="vendor" type="text"
class="txtsmall2" value="<%=variable%>" readonly="readonly"/>
I think you're looking for something like:
<input id="vendor" name="vendor" type="hidden"
value="<%=variable%>" /><span class="txtsmall2"><%=variable%></span>
Where you have a hidden input followed by a visible text element that is not an input but has the same value.
Changing type to hidden would hide the input field.
<input id="vendor" name="vendor" type="hidden"
class="txtsmall2" value="<%=variable%>" readonly="readonly"/>
As OP mentioned in a comment, if want to show the text content but not the borders, try:
<input style="border:0" "id="vendor" name="vendor" type="text"
class="txtsmall2" value="abc" readonly="readonly"/>
CSS can be in-line, internal, or external sheet. I kept it simple here.
Here is the HTML of my form:
<form action="" method="get">
<input name="name" type="text" value="a" id="a"/>
<input name="password" type="text" value="b" id="b"/>
<input type="submit" name="c" value="submit" id="c"/>
</form>
If I hit the enter key when the focus is on the "name" textbox, the form will be submitted, and the query string will be ?name=a&password=b&c=submit. Notice that the value of the submit button is present in the query string.
However, if I remove the second textbox, and repeat the steps above, then the query string will be ?name=a; the button value has disappeared.
Is this behavior normal, or is it an IE issue?
Buttons aren't usually used to hold values. The only purpose of passing the value is when you have multiple submit buttons and you need to tell which one was actually pressed. Sometimes a form will have a "update" and "delete" buttons, for example. This is why they don't pass on a value if not pressed.
It's an IE issue. Search for: [internet explorer submit enter].
