chromedp How to select specific textarea from multiple textareas with dynamic names
I have a page with multiple text areas consisting of dynamic names and the same class. This means I can't select them by id, name, class or type.
All I know is that out of the 5 textareas, I need the first one, and I want to change the value of that textarea.
Can anyone tell me how to do this using chromedp? Been trying for two days with no progress.
Find the answer:
const n = document.querySelector('.elementor-repeater-fields:nth-child(2) textarea'); console.log(n);
Correct answer
Use pseudo-class :first-child a> or :nth-child to select the target element. For example:
package main import ( "context" "fmt" "net/http" "net/http/httptest" "time" "github.com/chromedp/chromedp" ) func main() { ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, ` <html> <body> <textarea></textarea> <textarea></textarea> <textarea></textarea> </body> </html> `) })) defer ts.Close() opts := append(chromedp.DefaultExecAllocatorOptions[:], chromedp.Flag("headless", false), ) ctx, cancel := chromedp.NewExecAllocator(context.Background(), opts...) defer cancel() ctx, cancel = chromedp.NewContext(ctx) defer cancel() err := chromedp.Run(ctx, chromedp.Navigate(ts.URL), chromedp.Sleep(time.Second), chromedp.SetValue(`body>textarea:first-child`, "hello world!", chromedp.ByQuery), chromedp.Sleep(time.Second), chromedp.SetValue(`body>textarea:nth-child(2)`, "hello chromedp!", chromedp.ByQuery), chromedp.Sleep(3*time.Second), ) if err != nil { panic(err) } }

C is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.

Golang excels in practical applications and is known for its simplicity, efficiency and concurrency. 1) Concurrent programming is implemented through Goroutines and Channels, 2) Flexible code is written using interfaces and polymorphisms, 3) Simplify network programming with net/http packages, 4) Build efficient concurrent crawlers, 5) Debugging and optimizing through tools and best practices.

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
