如何获取使用Jquery动态添加的HTML表行记录？(How to get the HTML Table row records which is added dynamically using Jquery?)

 
  我想得到行记录，这是动态添加的。 如果我使用html添加行，我将获得输出。  
 
 一开始，表格中没有记录。 这是我的代码。  
 HTML代码  
<table class="table table-hover " id="queryTable">
    <thead>
        <tr>
           <th>Field Name</th>
           <th>Values</th>
        </tr>
    </thead>
    <tbody>

    </tbody>
</table>
 
  当用户单击ADD按钮时 ，将成功使用jquery添加行  
  JQUERY代码  
$('#queryTable > tbody:last-child').append('<tr><td class="FieldNameID">' + selectedField + '</td><td class="OperatorID"> IN(' + $("#txtFilterValue").val() + ')</td></tr>');
 
 
  到目前为止它工作正常。 现在，当用户点击任何一行时，我想选择行并在警告框中显示它，这是动态添加的。  

 
 I want to get the row records, which is added dynamically. I am getting an output if I add the row using html. 
 
At beginning there will be no records in table. this is my code. 
HTML Code 
<table class="table table-hover " id="queryTable">
    <thead>
        <tr>
           <th>Field Name</th>
           <th>Values</th>
        </tr>
    </thead>
    <tbody>

    </tbody>
</table>
 
 When user click ADD ButtonIt will be added rows using jquery successfully 
 JQUERY Code 
$('#queryTable > tbody:last-child').append('<tr><td class="FieldNameID">' + selectedField + '</td><td class="OperatorID"> IN(' + $("#txtFilterValue").val() + ')</td></tr>');
 
 
 Upto this it's working fine. Now, When user clicks on any row, I want to select the row and show it in alert box, which is added dynamcally.

 您需要使用sigsetjmp和siglongjmp而不是常规版本，因为常规版本无法正确恢复信号掩码。 这是您的代码的工作版本：  
#include <stdio.h>
#include <signal.h>
#include <setjmp.h>

jmp_buf env;

void handler(int sig) {
    printf("Invalid input , try again\n");
    siglongjmp(env , 1);
}

int main() {
    int x , y;

    signal(SIGFPE , handler);
    sigsetjmp(env, 1);
    scanf("%d%d" , &x , &y);
    printf("%d %d\n" , x, y);
    printf("%d\n" , x / y);
}
 
 顺便说一句，我尝试使用Joachim Pileborg在评论中建议的sigaction ，但它对我没有帮助。 我认为这里的关键是如果你只是简单的longjmp退出信号处理程序，信号上下文不会被恢复（意味着SIGFPE可能会处于禁用状态）。 

You need to use sigsetjmp and siglongjmp instead of the regular versions, because the regular versions do not properly restore your signal masks. Here is a working version of your code: 
#include <stdio.h>
#include <signal.h>
#include <setjmp.h>

jmp_buf env;

void handler(int sig) {
    printf("Invalid input , try again\n");
    siglongjmp(env , 1);
}

int main() {
    int x , y;

    signal(SIGFPE , handler);
    sigsetjmp(env, 1);
    scanf("%d%d" , &x , &y);
    printf("%d %d\n" , x, y);
    printf("%d\n" , x / y);
}
 
By the way, I tried using sigaction as suggested by Joachim Pileborg in the comments, but it did not help for me. I think the key here is that if you just plain longjmp to exit a signal handler, the signal context is not restored (meaning SIGFPE might be left in a disabled state).
