在移动浏览器中点击搜索框后,页面会立即刷新,但是在输入字符串并按Enter键后,PC才能使用
<form id="f1" name="f1" action="javascript:void()"
onsubmit=" if(this.t1.value!=null && this.t1.value!='')
parent.findString(this.t1.value);return false;">
<input type="text" id="t1" name="t1" value="" placeholder="Find Words" size="20">
<input type="submit" name="b1" value="Find">
</form>
答案 0 :(得分:0)
event.prevent默认用法:
<form name="f1" action="" >
<input type="text" name="t1" value="" placeholder="Find Words" size="20">
<input type="submit" value="Find">
</form>
document.forms.f1.addEventListener('submit',function(event)
{
event.preventDefault() // disable submit
console.log( this.t1.value )
// ...
})
