javascript按钮

将此添加到要单击的元素中:

onclick="setAVariable()"

然后在一个php文件中添加这个javascript函数:

function setAVariable(){ 
    //dostuff 
    var get = "<?php echo _GET ?>" ;
}

myTr.onclick = function () {
    // Make sure you have a keyboard focusable and a non-JS alternative!
    document.forms.myform.elements.myhiddeninput.value = someValue;
}
