Logout issue

Question

Hello I have a page with 2 dropdown and 3 textbox and button and using it as search filter which binds data to grid on button click. When i choose both dropdown and clicks on button it binds data to grid. But when enter value in any textbox and clicks on search button  it logs out. Even it does not go to debug to find the error. It looks there is issue only with every textbox . Please fiind below screenshot. Thanks in advance

Check the JavaScript code within the onclick event of the search button for any syntax errors. Typos or incorrect JavaScript syntax can cause the script to stop execution immediately preventing the debugger from being reached. and l ook for unhandled exceptions in the JavaScript console. These could be caused by invalid input missing variables or errors in your search logic. Add console.log() statements before and after each section of your JavaScript code related to the textbox input and search button click. This will help you track the execution flow and identify where the code stops. Log the values entered in the textboxes before submitting the search request. Since I dont have the code so I tried like this: Intermediary Name SELECT Option 1 Option 2 Product Name Action By User SELECT User 1 User 2 Proposal No Transaction ID Search Add the following script to debug and log the textbox values and the execution flow: document.getElementById(searchButton).addEventListener(click function () { try { // Log the input values to debug const intermediaryName = document.getElementById(intermediaryName).value; const productName = document.getElementById(productName).value; const actionByUser = document.getElementById(actionByUser).value; const proposalNo = document.getElementById(proposalNo).value; const transactionId = document.getElementById(transactionId).value; console.log(Intermediary Name: intermediaryName); console.log(Product Name: productName); console.log(Action By User: actionByUser); console.log(Proposal No: proposalNo); console.log(Transaction ID: transactionId); // Validate the input fields (optional) if (!proposalNo && !transactionId) { console.warn(Please enter a Proposal No or Transaction ID to search.); alert(Proposal No or Transaction ID is required.); return; } // Simulate sending the data to the server console.log(Submitting search request...); // Example AJAX call (replace with your actual implementation) // fetch('/search' { // method: 'POST' // headers: { // 'Content-Type': 'application/json' // } // body: JSON.stringify({ // intermediaryName // productName // actionByUser // proposalNo // transactionId // }) // }).then(response => response.json()) // .then(data => console.log('Search results:' data)) // .catch(error => console.error('Error:' error)); } catch (error) { console.error(An error occurred during search execution: error); } }); Use Console Logs : Open your browser's developer tools (F12 > Console tab). Look for logs of the textbox values and execution flow when you click the Search button. Track Errors : Check for JavaScript errors in the console. Errors like undefined or null values in the input fields may indicate issues. Validate Inputs : Ensure that all inputs are correctly assigned and logged before making any requests. Inspect Network Calls : Go to the Network tab in developer tools to check if the search request is sent to the server. Look for any failed requests or error codes.

If you're using a strongly typed language on the server (like C# or Java) check that the data received from the textboxes is correctly converted to the expected data types (e.g. integers dates). Incorrect conversions can lead to unexpected errors. and also test with various combinations of inputs (empty textboxes invalid input formats extreme values) to check your search logic handles all scenarios correctly.
