设置字段是否必填

有时，标准功能“显示属性联动”中的设置字段是否必填，并不能达到需求效果。这时就需要借助JS脚本了。

输入框和浏览框：

 1 /**
 2  * 设置字段必填/选填
 3  * @param {boolean} necessary true-必填;false-选填
 4  * @param {string} fieldId 字段id，如field12121
 5  * @param {string} spanImgId 界面“！”id，通常为field12121span，浏览框为field12121spanimg
 6  */
 7 function setNecessityOfField(necessary,fieldId, spanImgId){
 8     var viewtype=necessary?"1":"0";
 9     $('#' + fieldId).attr('viewtype', viewtype);
10     var oldFieldStr = $('input[name=needcheck]').val();
11     if(necessary){
12         newFieldStr=oldFieldStr.indexOf(fieldId)!=-1?oldFieldStr:oldFieldStr +',' +fieldId;
13     }else{
14         newFieldStr=oldFieldStr.replace(','+fieldId, '');
15     }
16     $('input[name=needcheck]').val(newFieldStr);
17     if(necessary&&$('#' + fieldId).val()!=""){
18         return;
19     }
20     var html=necessary?'<img src="/images/BacoError_wev8.gif" align="absMiddle">':'';
21     $('#' + spanImgId).html(html);
22 }

附件字段：

 1 /**
 2  * 设置附件字段必填/选填
 3  * @param {boolean} neccessary true-必填;false-选填
 4  * @param {string} fieldId 字段id，如field12121
 5  * @param {string} spanId 界面“（必填）”id，附件字段为field_12121span
 6  */
 7 function setNecessityOfEnclosureField(neccessary, fieldId) {
 8     var viewtype = neccessary ? "1" : "0";
 9     $('#' + fieldId).attr('viewtype', viewtype);
10     var oldFieldStr = $('input[name=needcheck]').val();
11     if (neccessary) {
12         newFieldStr = oldFieldStr.indexOf(fieldId) != -1 ? oldFieldStr : oldFieldStr + ',' + fieldId;
13     } else {
14         newFieldStr = oldFieldStr.replace(',' + fieldId, '');
15     }
16     $('input[name=needcheck]').val(newFieldStr);
17     if (neccessary && $('#' + fieldId).val() != "") {
18         return;
19     }
20     var spanId = fieldId.replace("field", "field_") + "span";
21     var html = neccessary ? "（必填）" : "";
22     $('#' + spanId).html(html);
23 }
