I want to retrieve max value for each combobox present in a web page, with xpath.
Here is a sample HTML containing several combobox with choices:
<label> <span class="invisible_spoken">Some choice</span>
<select class="select_class">
<option value="0">0</option>
<option value="1" >
1
</option>
<option value="2" >
2
</option>
</select>
</label>
<label> <span class="invisible_spoken">Some choice</span>
<select class="select_class">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</label>
<label> <span class="invisible_spoken">Some choice</span>
<select class="select_class">
<option value="0">0</option>
<option value="1">1</option>
</select>
</label
What I would want to retrieve is the maximum value of each combobox, sample output :
2, 3, 1
I've tried with an expression like :
//table[#id="rooms"]//select[contains(#class, "b_selectbox")]/option[not(//table[#id="rooms"]//select[contains(#class, "b_selectbox")]/option/#value > #value)]/#value
But it is returning just combobox max values of the maximum combo value, in the sample case just 3 that is the highest, in the case there will be two combobox with maximum values equals to 3, then it will return those 2 ...
Xpath Selector for Options with highest value.
//label/select[#class="select_class123"]/option[not(../option/#value > #value)]
o/p: Option elements with highest values.
(//label/select[#class="select_class"]/option[not(../option/#value > #value)])/#value
o/p: 2, 3, 1
Test XML XPath online:
<select class="select_class">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<select class="select_class">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<select class="select_class">
<option value="0">0</option>
<option value="1">1</option>
</select>
<select name="A">
<option value="1">Volvo</option>
<option value="2">Saab</option>
</select>
<select name="B">
<option value="1">test1</option>
<option value="2">test2</option>
</select>
<input type="Submit" >
After I submit, I want to show result from A and B. For example:
if($_POST['A']==1 && $_POST['B']==2){
echo 'true';
}else{
echo '0';
}
Is it possible to do this in joomla?
you have to enclosed this input fields into form tag. For example
<form method="post">
<select name="A">
<option value="1">Volvo</option>
<option value="2">Saab</option>
</select>
<select name="B">
<option value="1">test1</option>
<option value="2">test2</option>
</select>
<input type="Submit" >
</form>
Hope it will help

Its an AngularJS web application.
The select elements look identifiable based on their ng-model attribute - which is "month", "day" and "year". You can locate elements using the ng-* attributes by using a CSS (or XPath) locator:
browser.select(css: 'select[ng-model="month"]').select('07')
browser.select(css: 'select[ng-model="day"]').select('31')
browser.select(css: 'select[ng-model="year"]').select('2014')
If you tend to use the ng-model a lot for identification, you should add it to the list of validate locators. This will save you from having to write CSS/XPath locators.
require 'watir-webdriver'
Watir::HTMLElement.attributes << :ng_model
browser.select(ng_model: 'month').select('07')
browser.select(ng_model: 'day').select('31')
browser.select(ng_model: 'year').select('2014')
Note that the above suggestions assume that there is only one set of month/day/year fields on the page. If there are multiple, you will need to be more specific in the locators. In this case, it looks like the encompassing div element has an identifiable class - "bday-select-input":
birthday = browser.div(class: 'bday-select-input')
birthday.select(css: 'select[ng-model="month"]').select('07')
birthday.select(css: 'select[ng-model="day"]').select('31')
birthday.select(css: 'select[ng-model="year"]').select('2014')
I have this code
<div th:class="form-group">
<td><label class="control-label leftMargin10 rightMargin10" scope="col" th:text="#{insertHours.hhFrom}">Attivita'</label></td>
<td><select class="form-control" th:field="*{hhFrom}">
<option th:each="i : ${#numbers.sequence(0, 23)}" th:value="${i}" th:text="${i}" th:selected="${ i==9 } ">Options</option>
</select>
</td>
</div>
When I try to add a condition in th:selected it doesn't work.
I have also replaced with this code:
th:attr="${i==9}? selected=selected: '' "
but the result is the same.
The HTML
<select class="form-control" id="hhFrom" name="hhFrom">
<option value="0" selected="selected">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
<option value="13">13</option>
<option value="14">14</option>
<option value="15">15</option>
<option value="16">16</option>
<option value="17">17</option>
<option value="18">18</option>
<option value="19">19</option>
<option value="20">20</option>
<option value="21">21</option>
<option value="22">22</option>
<option value="23">23</option>
</select>
Thanks in advance to answers
You cannot use th:field along with th:selected.
If you replace th:field with name=someMeaningfullName the code will work just fine.
Check out this thread on the Thymeleaf forum for more information
Another hack that, is pretty simple and works, is to close the select tag: <select ... />
Please note /> at the end of first line:
<select th:field="*{percentage}" />
<option th:each="i : ${#numbers.sequence(0, 100)}" th:value="${i}" th:text="${i}" th:selected="${i==75}"></option>
</select>
Renders as:
<select id="percentage" name="percentage" />
<option value="0">0</option>
<option value="1">1</option>
...
<option value="74">74</option>
<option value="75" selected="selected">75</option>
<option value="76">76</option>
...
<option value="100">100</option>
</select>
Both web browser and Thymeleaf will handle this fine.
I used Thymeleaf v.3.0.9.RELEASE
Also I found out that if you put <div> tag around option fields, selected="selected" will also work. e.g
<select th:field="*{name}">
<div>
<option disabled="true" selected="selected" value="">Select</option>
<option value="1">first</option>
<option value="2">second</option>
</div>
</select>
