表单未提交即提交

Form is submitting without submit

本文关键字：提交 表单      更新时间：2024-02-14

我有一个表单元素，没有输入类型="submit"。我使用一个带有onclick的按钮来调用这样的函数：

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

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被注释掉。当我单击该按钮时，不会生成警报，并且表单仍然会提交。

想法？

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>

阻止窗体的默认操作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();
}

HTML

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

Kinjal是正确的。按钮的默认类型（未声明时）为"提交"。您必须声明type="button"以避免按钮提交表单。
