I have a lengthy form (250+ fields) that posts to a db. It is an online employment application. When an admin goes to look at an application that has been filed, the form is populated with data from the db. Input texts and textareas are replaced with the text they submitted but the radios and checkboxes are useful to keep as form elements. Disabling them makes them harder to read. Setting the .checked property to false onclick won't work because they may have been checked by the user filling out the app. Anyhow...

onclick="return false;"

这是我的解决方案(覆盖)Sencha ExtJS 7.2+(复选框和单选覆盖)

Ext.define('MyApp.override.field.Checkbox', {
    override: 'Ext.field.Checkbox',

    /**
     * OVERRIDE: to allow updateReadOnly to work propperly
     * @param {boolean} newValue
     *
     * To ensure the disabled state stays active if the field is still readOnly
     * we re - set the disabled state
     */
    updateDisabled(newValue) {
        this.callParent(arguments);

        if (!newValue && this.getReadOnly()) {
            this.inputElement.dom.disabled = true;
        }
    },

    /**
     * OVERRIDE: readonly for radiogroups and checkboxgroup do not work as other fields
     *     https://stackoverflow.com/questions/1953017/why-cant-radio-buttons-be-readonly
     *
     * @param {boolean} newValue
     *
     *  - use disabled on the field
     */
    updateReadOnly(value) {
        this.callParent(arguments);

        if (!this.getDisabled()) {
            this.inputElement.dom.disabled = value;
        }
    }
});

我发现使用onclick='this。Checked = false;'在一定程度上起了作用。单击的单选按钮将不会被选中。然而，如果有一个单选按钮已经被选中(例如，一个默认值)，该单选按钮将变为未选中。

<!-- didn't completely work -->
<input type="radio" name="r1" id="r1" value="N" checked="checked" onclick='this.checked = false;'>N</input>
<input type="radio" name="r1" id="r1" value="Y" onclick='this.checked = false;'>Y</input>

在这种情况下，保持默认值不变并禁用其他单选按钮将保留已经选中的单选按钮，并防止不选中它。

<!-- preserves pre-selected value -->
<input type="radio" name="r1" id="r1" value="N" checked="checked">N</input>
<input type="radio" name="r1" id="r1" value="Y" disabled>Y</input>

这个解决方案并不是防止默认值被更改的最优雅的方法，但无论是否启用javascript，它都是有效的。

尝试禁用属性，但我认为您不会得到单选按钮的值。 或者像这样设置图像:

<img src="itischecked.gif" alt="[x]" />radio button option

致以最亲切的问候。

一个相当简单的选择是创建一个javascript函数，在表单的“onsubmit”事件上调用，以启用单选按钮返回，这样它的值就会与表单的其余部分一起发布。 这似乎不是HTML规范上的一个遗漏，而是一个设计选择(一个逻辑选择，IMHO)，单选按钮不能像按钮一样是只读的，如果你不想使用它，那就禁用它。
