无法以chrome扩展名提交表单

Question

I am not able to submit form in chrome extension.

When did i try to submit form, then whole page is refreshing instead of submit data and get the result.

Manifest.js:

{
    "name": "BrowserExtension",
    "version": "0.0.1",
    "manifest_version": 2,
    "description" : "Description ...",
    "browser_action": {
        "default_icon": "icon.png" ,
        "default_title": "That's the tool tip"
    },
    "background": {
        "scripts": ["js/jquery-2.1.4.min.js", "background.js"],
        "persistent": false
    },
    "content_scripts": [{
        "matches": ["http://*/*", "https://*/*"],
        "js": ["js/jquery-2.1.4.min.js", "content.js"]
    }],
    "permissions": [
          "tabs", 
           "activeTab",    
           "https://www.irctc.co.in/eticketing/loginHome.jsf"
        ]
}

background.js:

chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
   if(changeInfo.status == 'complete')
   {

   if(tab.url === 'https://www.irctc.co.in/eticketing/mainpage.jsf')
   {
        chrome.tabs.executeScript(null, {file: "js/autofillMain.js"});
   }

   }
});

Autofillmain.js:

   var userName = document.getElementById("jpform:fromStation");
    userName.value = "PUNE JN - PUNE";

    var password = document.getElementById("jpform:toStation");
    password.value = "GWALIOR - GWL";

    var date = document.getElementById("jpform:journeyDateInputDate");
    date.value = "30-08-2015";

    $("#jpform").submit();'

Please let me know if you need any other information.

That site's form probably relies on the submit button being clicked to run some necessary code in the click handler.

Try calling the submit button's click() explicitly, something like this:

• via jQuery: $("#jpform [type='submit']:not([disabled])").click()
• via standard js: document.querySelector("#jpform [type='submit']:not([disabled])").click()
