问题描述
使用新信息更改问题
以前我问过以下问题.但是更多细节显示，如果通过取消选择某个应用程序(可能不是正确的术语)然后选择该应用程序来切换到其他应用程序，则该按钮有效.如果您关闭应用程序并重新启动，则该应用程序将无法再使用.很奇怪.我将在本段下面发布完整的页面代码，下面的所有内容都是旧问题以及------行下的部分代码

我尝试了10种找到的解决方案，但都无济于事.我有一个不能仅仅提交的表单，因为它接收回数据然后放入div.此代码适用于android，但不适用于iOS.(这是一个使用framework7和bootstrap，然后使用phonegap构建的HTML 5应用程序).这是一种搜索表单，可提交到服务器php页面，并将结果取回并放入div中.当您单击按钮时，iOS不会执行任何操作.
这是按钮代码:
< button class ="btn btn-primary" name ="Submit" value ="Search" id ="Submit">〜SEARCH〜</button> 以下是处理程序代码:
< script>var xmlhttp;var url;window.onload = function(){document.addEventListener("deviceready"，init，false);}函数init(){document.getElementById('Submit').addEventListener('click'，getData，false);}函数getData(){url ="http://www.mywebsite.org/myapp.php";url + =?cemetery =" + document.getElementById('cemetery').value;url + =& lastname =" + document.getElementById('lastname').value;url + =& first =" ="+ document.getElementById('firstname').value;$ .ajax({类型:获取"，网址:url，成功:功能(数据){document.getElementById('laloinfo').innerHTML =";document.getElementById('laloinfo').innerHTML =< strong>向下滚动以获取结果</strong>";/* document.getElementById('lalo2').innerHTML =数据；*/$(#lalo2").html(data);}});}
在此先感谢您的帮助.它使我发疯，并且经历了一周的酷刑.

解决方案
下面是一个视频，演示了如何直接调试iOS WebView.
步骤是:
- 在Mac上的Safari中，转到首选项...->高级，然后启用在菜单栏中显示开发"菜单
- 确保应用程序在模拟器上运行
- 在Safari中，选择开发->模拟器-iPhone(型号)->选择WebView -注意，当您在菜单中将鼠标悬停在WebView上时，WebView将会突出显示
- 开始Javascript调试
CHANGING QUESTION WITH NEW INFO
Previously I asked the question below. But more details show that if you go to switch to a different app by going to unselect the app (may not be the right term) and then selecting the app, the button works. If you shut down the app and restart it doesn't work again. Very strange. I'm posting the complete page code below this paragraph, everything below that is the old question and partial code under the ------ line

-----------------------------OLD QUESTION BELOW------------------------------
I've tried 10 solutions that I've found and none work. I have a form that can't just submit because it receives back data to then put into a div. This code is working for android, but not iOS. (This is an HTML 5 app using framework7 and bootstrap, then built with phonegap). It is a search form that submits to a server php page and takes the results back and puts them into a div. iOS does nothing when you click on the button.
Here is the button code:
<button class="btn btn-primary" name="Submit" value="Search" id="Submit">~SEARCH~</button>
Here is the handler code:
<script>
var xmlhttp;
var url;
window.onload = function()
{
document.addEventListener("deviceready", init, false);
}
function init()
{
document.getElementById('Submit').addEventListener('click', getData, false );
}
function getData(){
url = "http://www.mywebsite.org/myapp.php";
url += "?cemetery=" + document.getElementById('cemetery').value;
url += "&lastname=" + document.getElementById('lastname').value;
url += "&firstname=" + document.getElementById('firstname').value;
$.ajax({
type: 'get',
url: url,
success: function(data){
document.getElementById('laloinfo').innerHTML = "";
document.getElementById('laloinfo').innerHTML = "<strong>Scroll down for results</strong>";
/* document.getElementById('lalo2').innerHTML = data; */
$("#lalo2").html(data);
}
});
}
Thank you in advance for any help. It's driving me nuts and has been a week of torture.

解决方案
Here's a video demonstrating how to debug an iOS WebView directly.
This should make it easy to see where you're going wrong.
To create and open a Cordova app in Xcode for debugging:
[ ~] cordova create TestApp com.mydomain.testapp "TestApp"
Creating a new cordova project.
[ ~] cd TestApp/
[ ~/TestApp] cordova platform add ios --save
Using cordova-fetch for cordova-ios@~4.5.4
Adding ios project...
Creating Cordova project for the iOS platform:
Path: platforms/ios
Package: com.mydomain.testapp
Name: TestApp
iOS project created with cordova-ios@4.5.4
Discovered plugin "cordova-plugin-whitelist" in config.xml. Adding it to the project
Installing "cordova-plugin-whitelist" for ios
Adding cordova-plugin-whitelist to package.json
Saved plugin info for "cordova-plugin-whitelist" to config.xml
--save flag or autosave detected
Saving ios@~4.5.4 into config.xml file ...
[ ~/TestApp] open platforms/ios/TestApp.xcworkspace
[ ~/TestApp]
At this point in Xcode just choose your simulator and click the Run triangle:
The steps are:
- On the Mac in Safari, go to Preferences... -> Advanced and enable Show Develop menu in the menu bar
- Ensure the app is running on the simulator
- In Safari choose Develop -> Simulator -- iPhone (model) -> choose the WebView -- note the WebView will highlight as you mouse over it in the menu
- Begin Javascript debugging
这篇关于除非您退出应用并返回，否则按钮onclick事件在iOS中不起作用，然后它将起作用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
