Question

我有一个没有输入类型='submit'的表单元素。我使用带有onclick的按钮进行函数调用，如下所示：

<form method='post' action='build_meet.html' id='meet_builder_form'>
....
<button onclick='submit_this_form()' >Submit</button>
</form>

该功能定义为：

function submit_this_form() {
    var my_teams = [];
    for ( var i = 0 ; i < window.my_meet.teams.length; i++ ) {
        my_teams.push( window.my_meet.teams[i].team_id );
    }
    var my_teams_str = my_teams.join('|');
    document.getElementById('team_ids_list').value = my_teams_str;
    alert ( my_teams_str );
    //document.getElementById('meet_builder_form').submit();
}

请注意，实际提交表单的行已注释掉。当我单击按钮时，不会生成警报，并且表单仍会提交。

思想？

Answer 1

阻止表单的默认操作submit。

function submit_this_form(e) {
    e.preventDefault();
    var my_teams = [];
    for ( var i = 0 ; i < window.my_meet.teams.length; i++ ) {
        my_teams.push( window.my_meet.teams[i].team_id );
    }
    var my_teams_str = my_teams.join('|');
    document.getElementById('team_ids_list').value = my_teams_str;
    alert ( my_teams_str );
    //document.getElementById('meet_builder_form').submit();
}

<强> HTML

<form method='post' action='build_meet.html' id='meet_builder_form'>
....
<button onclick='submit_this_meet(event)' >Submit</button>
</form>

Answer 2

试试这个，

<form method='post' action='build_meet.html' id='meet_builder_form'>
....
<button type="button" onclick='submit_this_form()' >Submit</button>
</form>

Answer 3

Kinjal是对的。按钮的默认类型（未声明时）是“提交”。您必须声明type="button"以避免按钮提交表单。

表格提交无需提交
