提交来自javascript的名称/值对? [英] Submit name value pair from javascript?

问题描述

JS是否可以通过document.testform.submit();提交名称/价位对? ? 还是必须通过html标签提交，例如

Can JS submit name/vale pairs through a document.testform.submit(); ? or does it have to be submitted through the html tags, for example

<INPUT TYPE="text" NAME="inputbox1" VALUE="This is such a great form!" SIZE=50><P>

推荐答案

通常，您在表单中包含< input type ="hidden">，并在事件处理程序提交之前设置所需的值.

Typically you include an <input type="hidden"> in the form, and set the value you want in the event handler before it gets submitted.

<form method="post" action="thing" id="sandwich"><fieldset>
    <input type="text" name="inputbox1" value="This is such a great form!" />
    <input type="hidden" name="jsremark" />
</fieldset></form>

<script type="text/javascript">
    document.getElementById('sandwich').onsubmit= function() {
        this.elements.jsremark.value= 'Secretly it aint that great';
        return true;
    }
</script>
