Hello,
Can some one help me with JavaScript to read the Each row data from GridView and store it in the Array to use after postback.
GridView has 7 columns , where column 4 and 6 has TextBox and RadioButton list controls respectively.
Before postback, i would like to store textbox values and radiobutton selected index.
Regards,
VK

Where are you stuck?
1. Create array
2. Loop through rows in gridview
3. Add values to array,
4. Write to cookie, localStorage, Session, something
5. Etc.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

Hello everyone.
I just recently started coding and I thought a good first project would be to automate inventory at work.
I'm working on a chrome extension that loads inventory, asks for the asset tag, searches for the tag, and then clicks the results of the search.
So far everything is great except for when I try to click the results of the search.
It doesn't matter what I try the click function always runs before everything else.
It doesn't make sense to me; here's what I have.
function getInfo() {
chrome.storage.sync.get('state', function (value) {
if (value.state == 'start'){
chrome.storage.sync.set({'state': 'noRun'})
getTag()
}
})
}
function getTag() {
var tagNum = prompt('Enter Asset Tag')
searchTag(tagNum)
}
function searchTag(search) {
document.getElementById('serial').value = search
document.forms.form1.submit()
setTimeout(function(){clickResults(), 15000})
}
function clickResults() {
document.getElementsByClassName('resultheader')[1].click()
}
getInfo()
If I move the setTimeout() to inside the clickResults() it breaks. 
Any help is appreciated.
Thank you!

What is "everything else?"

That's because you create infinite recursion.

Hi all,
I am trying to execute javascript in a PDF that will allow the form to be submitted via email with a subject line that will pull a value from a field in the form. I am able to get the email portion to work, but I have not been able to customize the subject line to pull from the field. Below is the base script I am using to send the email without the customized subject line:
this.submitForm({
cURL: "mailto:aamos@lrrc.com?subject=TSC Form&body=",
cSubmitAs: "PDF"
});
The field I am wanting to pull from is labeled "Name". Below was one of my attempts, all of which have not worked.
Failed Script:
this.submitForm({
var Name = this.getField("Name").value;
cURL: "mailto:aamos@lrrc.com?subject=TSC Form (Name)&body= ) ",
cSubmitAs: "PDF"
});
Can someone point me in the right direction or help me with where I went wrong in the script? I am new to this and glad I was able to execute the first script successfully but I feel I am in over my head with the customization.
Thanks in advance for your assistance.
AA

As your entire text is in quotes
"mailto:aamos@lrrc.com?subject=TSC Form (Name)&body= ) "
it's taken as a literal piece of text. How does js know that when you say "Form" it means the word "Form" but when you say "Name" it means the value of a variable called "Name"? Instead you need to use string concatination to construct the string you want;
"mailto:aamos@lrrc.com?subject=TSC Form (" + Name + ")&body= ) "
|
|
|
|
|
That makes sense, I revised the script but now I am getting the following error.
SyntaxError: missing } after property list
line 7: cSubmitAs: "PDF"
The script I was using:
var name = this.getField("Name").value;
this.submitForm({
cURL: "mailto:aamos@lrrc.com?subject=TSC Form (" + Name + ")&body= ) "
cSubmitAs: "PDF"
});
I added a comma, a semicolon, a curly bracket... didn't change the error. This was not an error previously and that syntax worked when I wasn't trying to do anything complex with the subject line. Do I have to change the syntax because of what I am trying to accomplish with the subject line?
|
|
|
|
|
You need a comma after the end quote
var name = this.getField("Name").value;
this.submitForm({
cURL: "mailto:aamos@lrrc.com?subject=TSC Form (" + Name + ")&body= ) ",
cSubmitAs: "PDF"
});

What part of "don't just dump your unformatted code and expect us to figure out what it's supposed to be doing" did you not understand?
Edit your post. Remove any code that isn't relevant. Add a clear description of what the code is supposed to be doing, what the code is actually doing, and the full details of any errors and exceptions. Remember to tell us which line of code the error is thrown from.
And while you're at it, remove the duplicate copy of this post from QA.

i think you are not understanding the code properly just read the subject first and chk the code where i mentioned DID YOU NOT UNDERSTAND .dont just copy and paste your statements
|

|

You have repeatedly been told, by multiple people, not to dump your code and expect us to figure it out.
And yet you continue to dump your code and expect us to figure it out.
We are NOT here to do your job for you. If you can't be bothered to put any effort into asking a question, then why should we bother to try to help you?!

Please do not just dump a load of unformatted code and expect someone to figure out what it is supposed to be doing. Edit your question and explain the problem properly, with only the relevant portions of the code, properly enclosed within <pre> tags for readability.

sorry for the inconvinience plz help m out i reposted my question with proper formatt

No, you have just dumped the same totally unformatted code. Please stop doing this. Post only the code (enclosed within <pre>) that demonstrates your problem, as I already suggested. And please add a proper description of your problem.

Hi,
I have two JSON objects:
JSON Object 1
[{
"date":
[
"date-value1",
"date-value2,
........ ,
"date-value729"
]
}]
JSON Object 2
{
"data": [
{
"body": [ "body1" ],
"link": "link1",
"title": [ "title1" ]
},
...........
{
"body": [ "body729" ],
"link": "link729",
"title": [ "title729" ]
}
]
}
How can I merge the properties of these 2 JSON objects and have the following example as an output for all 729 records of data:
{
"data": [
{
"body": [ "body1" ],
"link": "link1",
"title": [ "title1" ].
"date": "date1"
},
...........
{
"body": [ "body729" ],
"link": "link729",
"title": [ "title729" ]
"date": "date729"
}
]
}
Examples that I found online are mainly about merging two identical JSON objects.
Thank you in advance for your time and consideration.

I already answered this in the C# forum; please do not repost. And please make up your mid, is this C# or Javascript?
|
|
|
|
|
Let's look at the following code.
(function() {
var a = b = 5;
})();
console.log(b);
According to you, the output of the console output will look like?

|
|
|
|
If you do not know the answer, then either reread your reference guides, or run the code to see the results.
