I have an asp:ListBox control on my web page. I am trying to select an item in the list using javascript. After looking at the underlying structure I have tried:
catListBoxCtl[0].Selected = true;
Which does indeed set the 'selected' value to true but it doesn't highlight the appropriate row. I am just trying to replicate what a user does when you select a row using a mouse. How do you select a row programatically so that it get's highlighted etc?
Thanks.
I think you're missing the reference to the options. Try:
catLIstBoxCtl.options[0].selected = true;

I have created dynamically row with drop-down list, i want to get all selected values from dropdowns of rows with JQuery. Please help me.
Since you haven't posed any code snippet, I'm just gonna wing it, assuming it's a standard <select>-box.
// Loop all parents and grab the value which is set by the browser whenever update occurs.
var values = [...document.querySelectorAll('select')].map(x =>x.value)
I'm trying to set a value for a selection dropdown using javascript. Please see the pictures below. When I manually change the value of the dropdown list (by clicking), the timeline changes in accordance to the new value.
selection dropdown
timeline
When I do the following with javascript:
myDropdown.selectedIndex = 4;
The value is changed in the dropdown, but it doesn't update on the timeline. Is there any way to trigger this update?
I solved it by going through a huge javascript file.
What eventually worked was to call the dropdown change function with: $(".timeslotdrop").change();
I am pretty new to web-scraping and have limited html/js knowledge. I am trying to select a value in a drop down box. My code manages to loop over the options in the drop down list and recognizes the one I want, I just can't seem to select it.
code:
`For Each opt In ieDoc.getElementById("dealerCodeList").Options
If opt.innerText = 9265 Then
opt.Focus
opt.Selected = True
opt.setAttribute("selected") = "selected"
Exit For
End If
Next`
The website I am using requires login access so I have attached screenshots. You can see it's the drop down list in the top left hand corner that I am trying to select a value for. Thanks in advance!

I have developed my application using ExtJs 4.1. I have a combobox which gets populated using Ajax call. Once the comobox is populated, I need to find an item by name and then first the select event for that item.
The problem is the way combo-box is rendered by ExtJS. I am not sure how to select an item in the right manner. CombBox is not really a <select> element but a text input with a detached drop-down list that's somewhere at the bottom of the document tree.
I do not want to hard code the id's as ExtJS randomly generate the id.
This is how the generated HTML looks
You can check the example of ExtJs combobox here
Without testing, I would suggest,
var x = require("casper").selectXPath;
casper.thenClick(".x-form-trigger.x-form-arrow-trigger")
.wait(100)
.thenClick(x("//li[contains(#class,'x-boundlist-item') and contains(text(),'Alaska')]"))
.wait(100, function(){
this.capture("screenshot.png");
});
You might also need to move the mouse into position before clicking. Use
casper.then(function(){
this.mouse.move(selector)
});
Since you have the ComboBox in a form, you could use the "name" property in the ComboBox definition and select it with:
Ext.getCmp("idOfThePanel").down('form').getForm().findField('name');
Another option, use the "reference" property. In this case I'm not sure which is the correct way to select the ComoBox:
Ext.getCmp("idOfThePanel").down('form').getForm().lookupReference('reference');
or
Ext.getCmp("idOfThePanel").lookupReference('reference');
I have a gridview with several fields. Fields in question are PreviousPoints, GainedPoints, TotalPoints. In the edit mode PreviousPoints is not editable, just data bind, GainedPoints is a drop down list and Total Points is a Drop Down List.
When GainedPoints drop down list selected value changes, I need the TotalPoint selected value to be set to the value of PreviousPoints control + GainedPoints selected value.
But, I cannot refresh the whole page using post back.
How can it be done using JavaScript or something similar without reloading the page?
you can use the onselect() function in javascript and have your computations there.
