document.write('<a href="javascript:void(0)" onClick="javascript:callconfirm(b1checkConfirm.bind({p1: Hello, p2:World}),"Hello")" >Click</a>');

</body>

Answer 1

您需要逃避"：

<script type="text/javascript">

document.write('<a href="javascript:void(0)" onClick="javascript:callconfirm(b1checkConfirm.bind({p1: Hello, p2:World}),\"Hello\")" >Click</a>');
</script>

因为代码会认为onClick事件在你的第二个"之后完成

Answer 2

您的问题是document.write的这一部分：

b1checkConfirm.bind({p1: Hello, p2:World}),"Hello"

Hello 和 World 必须进行转义，因为它们是HTML的一部分，您可能会写：

b1checkConfirm.bind({p1: &apos;Hello&apos;, p2: &apos;World&apos;}),&apos;Hello&apos;

摘录：

function callconfirm(cb,pmessage)
{
    // var isConfirmed
    BootstrapDialog.confirm({
        title: 'WARNING',
        message: pmessage,
        type: BootstrapDialog.TYPE_WARNING, // <-- Default value is BootstrapDialog.TYPE_PRIMARY
        closable: false, // <-- Default value is false
        draggable: false, // <-- Default value is false
        btnCancelLabel: 'Do not drop it!', // <-- Default value is 'Cancel',
        btnOKLabel: 'Drop it!', // <-- Default value is 'OK',
        btnOKClass: 'btn-warning', // <-- If you didn't specify it, dialog type will be used,
        callback:cb /*function(result) {
         // result will be true if button was click, while it will be false if users close the dialog directly.
         if(result) {
         return true;
         }else {
         return false;
         }
         }*/
    });


}


function b1checkConfirm(result,id)
{
    //callconfirm();
    console.log("B1 click and result is "+result);
    console.log(this.p1);
    console.log(this.p2);
}

document.write('<a href="javascript:void(0)" onClick="javascript:callconfirm(b1checkConfirm.bind({p1: &apos;Hello&apos;, p2: &apos;World&apos;}),&apos;Hello&apos;)" >Click</a>')
