知识点总结
1.json格式标准
{
‘key’:"value"
}
{"state":"1","msg":"\u7b80\u5386\u6295\u9012\u6210\u529f\uff01"}
前端jquery ajax提交formdata
$.ajax({
})
formdata 获取表单数据 包括文件上传
HTML
<form class="am-form" id="recruitinfo">
<div class="col-lg6 col-md-6 col-xs-12 m1rem">
<label>姓名</label>
<input type="text" name="post[name]" id="name" required >
</div>
<div class="col-lg6 col-md-6 col-xs-12 m1rem">
<label>手机号</label>
<input type="text" name="post[iphone]" id="iphone" required>
</div>
<div class="col-lg10 col-md-10 col-xs-12 m2rem">
<label>附件简历:(您的详细信息请都写在简历上,只接受word文档)</label>
<div class="am-form-group am-form-file">
<button type="button" class="am-btn am-btn-danger am-btn-sm">
<i class="am-icon-cloud-upload"></i> 选择要上传的简历</button>
<input id="doc-form-file" type="file" name="doc" >
</div>
<div id="file-list"></div>
<script>
$(function() {
$('#doc-form-file').on('change', function() {
var fileNames = '';
$.each(this.files, function() {
fileNames += '<span class="am-badge">' + this.name + '</span> ';
});
$('#file-list').html(fileNames);
});
});
</script>
<input type="hidden" name="post[jobname]" id="jobname" value="{$data.job}">
<input type="hidden" name="post[jobnameid]" id="jobnameid" value="{$data.id}">
</div>
<div class="col-lg-6 col-md-6 col-xs-12">
<button type="submit" class="am-btn am-btn-primary" onclick="submitform()">提交</button>
<a href="javascript:window.history.back(-1);" class="am-btn am-btn-default">返回</a>
</div>
</form>
JS
<script type="text/javascript">
function submitform() {
event.preventDefault();
var form =document.getElementById('recruitinfo'),
formdata = new FormData(form);
var url = '{:url("recruitinfo/postfrom")}';
$.ajax({
url:url,
type:'post',
data:formdata,
dataType:'json',
processData:false,
contentType:false,
success:function (res) {
console.log('请求成功!')
console.log(res)
},
error:function (XMLHttpRequest, textStatus, errorThrown) {
console.log('出错啦!')
console.log(XMLHttpRequest);
console.log(textStatus);
console.log(errorThrown);
}
})
}
</script>
php json_encode()函数转成json
$callbackinfo = array(
'state' => '1',
'msg' => '简历投递成功!',
);
$jsondata =json_encode($callbackinfo);
echo $jsondata;
问题
1.前端SyntaxError: Unexpected token < in JSON at position 0 报错
报错原因
使用的thinkphp5
没想到是因为使用了dump()函数 var_dump 这些最后echo出来的不正确导致的,还要要按标准格式来啊
解决方法
去掉dump相似的函数
